The characteristic features in the geologic record are only present from a large impact are Ejecta blanket, Complex crater, Buried impact breccia, and Shocked quartz.
An impact crater's ejecta blanket is a typically symmetrical apron of ejecta that is heavily layered near the rim and thin to discontinuous at the blanket's outer border. However, the creation process does not end with excavation as meteorite craters get larger. The parabolic hole for such craters appears to be too enormous to maintain itself, and it collapses as a result, producing a variety of morphologies. The ultimate depression is referred to as a complex crater.
A sedimentary rock known as breccia is made up of large, angularly shattered pieces of minerals or rocks that are bound together by a fine-grained matrix. Shocked quartz is a kind of quartz with a unique microscopic structure from regular quartz. Quartz's crystalline structure deforms along internal planes at high pressure (but constrained temperature).

What can cause a gap in the rock record? question 12 options: erosion lack of rock deposition both erosion and lack of rock deposition neither erosion nor lack of rock deposition
That can cause gaps in the rock record are erosion and lack of rock deposition.
Erosion is a change in the shape of soil or rock that can be caused by the force of water, wind, ice, the influence of gravity, or living organisms. Uncontrolled soil erosion can cause harm to humans and ecosystems. Erosion is the process of washing away the soil by the force of water or wind. Erosion can occur naturally or as a result of human actions. One of the triggers for human-caused erosion is soil erosion on mountain slopes due to deforestation.
The erosion process involves three sequential events, namely sloughing, transport, and deposition. When everything in nature is in balance, natural erosion usually doesn't lead to disaster, except in extreme cases. This is because the transported soil particles are balanced with the amount of soil formed. Unlike the case when humans start destroying nature, the erosion process will be accelerated. The top layer of soil becomes thinner. As a result, more of the soil layer is washed away with the water.

what is extrusive rock
Answer:
Here's your answer
Explanation:
Extrusive rock, any rock derived from magma (molten silicate material) that was poured out or ejected at Earth’s surface. By contrast, intrusive rocks are formed from magma that was forced into older rocks at depth within Earth’s crust; the molten material then slowly solidifies below Earth’s surface, where it may later be exposed through erosion. Extrusive rocks are usually distinguished from intrusive rocks on the basis of their texture and mineral composition.

what degree of environmental impact is associated with each of the following three sources of oil? low impact moderate impact high impact crude oil shale oil oil sand
The degree of environmental impact is associated with each of the following three sources of oil- Low impact: Crude oil - Moderate impact: Shale oil - High impact: Oil sands.
The environmental impact associated with each source of oil varies based on factors such as extraction methods, processing techniques, and waste management. Crude oil, extracted from conventional oil reservoirs, generally has a lower environmental impact compared to other sources. While there can still be environmental concerns related to drilling, transportation, and potential oil spills, the overall impact is considered relatively low.
Shale oil, obtained through hydraulic fracturing (fracking), has a moderate environmental impact. The extraction process involves injecting large volumes of water, chemicals, and sand into the rock formations, which can lead to water contamination and disruption of ecosystems. However, compared to oil sands, shale oil extraction generally has a lower land footprint and water usage.
Oil sands, also known as tar sands, have a high environmental impact. Extracting oil from oil sands involves extensive surface mining or in situ extraction methods, which result in significant habitat destruction, water consumption, and greenhouse gas emissions. The extraction and processing of oil sands are energy-intensive and require the use of large amounts of water, often leading to water pollution and the release of carbon dioxide and other pollutants into the atmosphere.

What are three main challenges of water scarcity in Saudi Arabia
Answer:
1. griculture uses 85 percent of water in this region. It is common to misuse land by heavy irrigation in the Middle East. In the area droughts are more frequent, and contribute to the changing landscape. The overuse of water in agriculture is affecting the countries' already undersized water resources.
2. Desalination plants are an overuse of water resources in the Middle East. Seventy percent of desalination plants in the world are located in this area, found mostly in Saudi Arabia, the United Arab Emirates, Kuwait, and Bahrain. While the plants produce water needed for the arid region, they can manufacture problems for health and the environment. The seawater used most in desalination plants has high amounts of boron and bromide, and the process can also remove essential minerals like calcium. Also, the concentrated salt is often dumped back into oceans where the increased salinity affects the ocean's environment.
3.A report from the Emirates Industrial Bank in 2005 said that the UAE had the highest per capita consumption of water in the world. Additionally, for the past thirty years the water table of this region has dropped about one meter per year. At this current rate, the UAE will deplete its natural freshwater resources in about fifty years. Even with a large amount of desalination plants to reduce water deficiency, the UAE needs to adjust its water use habits before its energy consumption doubles in 2020.

all molecules (like molecules of water or carbon dioxide) are made up of? O hydrogen O groups of stars O two or more atoms O very small pieces of dust, from the material that lies between the stars O photons
The correct anser s otpion 3. All molecules, including water and carbon dioxide, are made up of two or more atoms. These atoms combine through chemical bonds to form molecules.
Molecules are the basic units of a compound, which is a substance made up of two or more elements. Water (H2O) and carbon dioxide (CO2) are examples of molecules. In the case of water, two hydrogen (H) atoms combine with one oxygen (O) atom to form the H2O molecule. For carbon dioxide, one carbon (C) atom combines with two oxygen (O) atoms to form the CO2 molecule.
The atoms in a molecule are held together by chemical bonds, which involve the sharing or transfer of electrons between atoms. The process of atoms combining to form molecules is called a chemical reaction. The other options mentioned, such as groups of stars, small pieces of dust, and photons, do not relate to the composition of molecules. Molecules are specifically formed from two or more atoms of elements combining through chemical bonds.

Write a paragraph about Natural Recourses of Egypt.
Answer:
Resources and power
Compared with the physical size of the country and the level of its population, Egypt has scanty mineral resources. The search for petroleum began earlier in Egypt than elsewhere in the Middle East, and production on a small scale began as early as 1908, but it was not until the mid-1970s that significant results were achieved, notably in the Gulf of Suez and portions of the Western Desert. By the early 1980s Egypt had become an important oil producer, although total production was relatively small by Middle Eastern standards.
The bulk of Egypt’s petroleum comes from the Morgan, Ramadan, and July fields (both onshore and offshore) in the Gulf of Suez, which are operated by the Gulf of Suez Petroleum Company (commonly known as Gupco), and from the Abū Rudays area of the Sinai on the Gulf of Suez. Egypt also extracts oil from fields at Al-ʿAlamayn (El-Alamein) and Razzāq in the Western Desert. Active drilling for oil, involving several international interests, including those of the United States and several European countries, has continued in both the Eastern and the Western deserts, with marked success during the 1990s and early 21st century.
In the process of searching for oil, some significant natural gas deposits have been located, including substantial deposits in the delta and in the Western Desert, as well as offshore under the Mediterranean Sea. Wells have been established in the Abū Qīr area, northeast of Alexandria. A joint Egyptian-Italian gas discovery was made in the north delta near Abū Māḍī in 1970; this was developed partly to supply a fertilizer plant and partly to fuel the industrial centres in the north and northwest delta. In 1974 Abū Māḍī became the first Egyptian gas field to begin production. Other natural gas fields are located in the Western Desert, the delta, the Mediterranean shelf, and the Gulf of Suez, and by the early 21st century natural gas production had begun to rival that of oil, both as a source for domestic consumption and as a commodity for export.
Egypt has several oil refineries, two of which are located at Suez. The first of Egypt’s twin crude pipelines, linking the Gulf of Suez to the Mediterranean Sea near Alexandria, was opened in 1977. This Suez-Mediterranean pipeline, known as Sumed, has the capacity to transmit some 2.5 million barrels of oil per day. The Sumed pipeline was financed by a consortium of Arab countries, primarily Saudi Arabia, Kuwait, and Egypt. In 1981 a crude oil pipeline was opened to link Raʾs Shukhayr, on the Red Sea coast, with the refinery at Musṭurud, north of Cairo. Additional oil pipelines link Musṭurud with Alexandria, and fields near Hurghada to terminals on the Red Sea.
Several of Egypt’s major known phosphate deposits are mined at Isnā, Ḥamrāwayn, and Safājah. Coal deposits are located in the partially developed Maghārah mines in the Sinai Peninsula. Mines located in the Eastern Desert have been the primary source for manganese production since 1967, and there are also reserves of manganese on the Sinai Peninsula. Iron ore is extracted from deposits at Aswān, and development work has continued at Al-Baḥriyyah Oasis. Chromium, uranium, and gold deposits are also found in the country.
The Nile constitutes an incomparable source of hydroelectric energy. Before the completion of the Aswān High Dam power station in 1970, only a small volume of Egyptian electricity was generated by hydropower, with thermal plants burning diesel fuel or coal being the principal producers. For several years after the High Dam station went into operation, most of the country’s electricity was generated there. Its original 12 turbines have a generating capacity of about 2 million kilowatts; the Aswān II hydroelectric power station (completed 1986) has added another 270,000 kilowatts of capacity to the system. Actual power production from the High Dam has been limited, however, by the need to reconcile demands for power with the demands for irrigation water. Moreover, Egypt’s booming population and growing need for energy has forced the government to construct additional thermal plants, many of them fueled by the country’s abundant reserves of natural gas. Thermal plants now generate some four-fifths of the country’s electricity.

An island is 2.1mi due north of its closest point on a straight shoreline. A visitor is staying at a cabin on the shore that is 7.9mi from that point. The visitor is planning to go from the cabin to the island. Suppose that the visitor runs at a rate of 5mph and swims at a rate of 1mph. How far should the visitor run before swimming to minimize the time it takes to reach the island? Assume that the distance from the point on the shore closest to the island and the point at which the visitor: begins swimming is x. Then the time spent running by the visitor as a function of x is T r
=hr Assume that the distance from the the island and the point at which the visitor begins swimming is y. Then the time spent swimming by the visitor as a function of y is T s
=hr What is the total time spent running and/or swimming by the visitor as a function of x ? T(x)= hr How far should the visitor run from the cabin in order to minimize the time it takes for them to reach the island? mi What is the minimum amount of time it will take for the visitor to reach the island from the cabin? hr NOTE: you may use decimals in your answers to this problem. If you enter an answer containing decimals, make sure it is correct to at least 3 decimal places.
The visitor should run a distance of 7.9 miles from the cabin to minimize the time it takes to reach the island.
To determine the distance the visitor should run before swimming to minimize the time it takes to reach the island, we need to find the minimum point of the total time function, T(x).
Given:
Distance from the point on the shore closest to the island to the cabin = 7.9 mi
Distance from the island to the point at which the visitor begins swimming = y
Running speed of the visitor = 5 mph
Swimming speed of the visitor = 1 mph
Let's derive the total time function:
T(x) = T_r + T_s
To find T_r, we divide the distance to be covered by running (x) by the running speed:
T_r = x / 5
To find T_s, we divide the distance to be covered by swimming (y) by the swimming speed:
T_s = y / 1 = y
Substituting these values into the total time function:
T(x) = (x / 5) + y
We know that the distance from the cabin to the island is the sum of the distances covered by running and swimming:
x + y = 2.1
Rearranging the equation, we get:
y = 2.1 - x
Substituting this value of y into the total time function:
T(x) = (x / 5) + (2.1 - x)
Simplifying the equation:
T(x) = (x / 5) + 2.1 - x
To minimize the time, we differentiate T(x) with respect to x and set it equal to zero:
d(T(x)) / dx = (1 / 5) - 1 = 0
1 / 5 - 1 = 0
-4 / 5 = 0
Since -4 / 5 is not equal to zero, there is no critical point. We can conclude that the minimum time is achieved when the visitor runs the entire distance from the cabin to the island.
Therefore, the visitor should run a distance of 7.9 miles from the cabin to minimize the time it takes to reach the island.
The minimum amount of time it will take for the visitor to reach the island from the cabin is T(7.9) = (7.9 / 5) + 2.1 - 7.9 = 1.58 + 2.1 - 7.9 = 0.78 hours (or approximately 46.8 minutes).
