The majority of the mass of an individual spiral galaxy is believed to be composed of dark matter.

Spiral galaxies, including our Milky Way galaxy, consist of various components. These components include stars, gas, dust, and dark matter. Dark matter is a form of matter that does not emit, absorb, or reflect electromagnetic radiation, making it invisible and challenging to detect directly. Its presence is inferred through its gravitational effects on visible matter.

Studies based on observations and computer simulations suggest that dark matter makes up a significant portion of the mass of spiral galaxies. It is estimated that dark matter can account for about 85% to 90% of the total mass of a spiral galaxy, while the remaining mass is attributed to visible matter, primarily stars, gas, and dust.

The dominance of dark matter in the mass of a spiral galaxy is inferred from various observations, such as the rotational velocity of stars and gas within the galaxy. The observed rotational velocities are higher than what could be explained by the visible matter alone, indicating the presence of additional mass in the form of dark matter.

Despite its invisible nature, dark matter plays a crucial role in the formation and evolution of galaxies. Its gravitational pull helps in holding galaxies together and shaping their structures, including the formation of spiral arms and the distribution of stars and gas within the galaxy.

However, it's important to note that our understanding of dark matter is still an active area of research, and scientists are working to unravel its nature and properties through ongoing studies and experiments.

Answer:

Aquatic living organisms use oxygen dissolved in water for respiration.

Explanation:

In this diagram, we can see very well how the cycle of oxygen works and what is involved in it. One thing is missing from it though, that being the aquatic living organisms and their role in the cycle. We only have a circulation of oxygen between the ocean and the atmosphere presented, but no living organisms are depicted.

The aquatic living organisms are crucial for the oxygen cycle, as they actually have a much larger contribution than the terrestrial living organisms. The amount of oxygen that is found in the ocean is far greater than the one on land. It is the aquatic organisms that actually managed to make the biggest contribution to the changes in the atmosphere, which enabled life on land later.

Answer:

Hydrosphere-Atmosphere

Explanation:

The water in the glass evaporated, moving from the glass to the atmosphere. This is a hydrosphere-atmosphere interaction.

Addison can see approximately X feet farther to the horizon compared to Kaylib.

To determine how much farther Addison can see to the horizon, we need to calculate the difference in their eye-level heights. Let's assume that Addison's eye-level height is Y feet above sea level. The distance to the horizon can be calculated using the formula:

d = √(2Rh)

where d is the distance to the horizon, R is the radius of the Earth (approximately 3,959 miles or 20,902,000 feet), and h is the eye-level height above sea level.

For Kaylib, with an eye-level height of 48 feet above sea level, the distance to the horizon can be calculated as:

d1 = √(2 * 20,902,000 * 48) ≈ 337,497 feet

For Addison, with an eye-level height of Y feet above sea level, the distance to the horizon can be calculated as:

d2 = √(2 * 20,902,000 * Y)

To find the difference in their line of sight, we subtract d1 from d2:

Difference = d2 - d1

Therefore, Addison can see approximately X feet farther to the horizon compared to Kaylib.

Answer:

The climate it very dry,humid and got.

Methane levels in the atmosphere will increase because melting or thawing will lead to an increase in the amount of organic matter that will decompose.

Methane is a powerful greenhouse gas that is created by both natural and human processes, including agriculture and the extraction of fossil fuels. Over the past few decades, its atmospheric concentrations have been continuously rising, causing climate change.

The effects of climate change, such as sea level rise, extreme weather events, and the loss of biodiversity, could be made worse if the trend of rising methane levels persists.

It is crucial that actions are taken to decrease the causes of methane emissions and lessen their negative effects on the environment.

A Pacific MP air mass moving inland (eastward) and across the United States will typically become dry by the time it gets east of the Rocky Mountains.

An air mass is a huge body of air with almost consistent temperature, humidity, and pressure throughout the same horizontal layer. These masses of air are classified based on their temperature and humidity. They are responsible for the large-scale weather patterns that affect the surface of the planet.

According to the question, when a pacific MP air mass moves inland (eastward) and across the United States, it will typically become dry by the time it gets east of the Rocky Mountains.  Hence, the correct answer is "dry."

The amount of annual snowfall will drop, the amount of annual rainfall will rise, and the water storage capacity will not be sufficient to repair the damage is impact of global warming.

Multiple lines of evidence indicate that the global warming has changed since the pre-industrial era, and that these changes have had an impact on ecosystems, species, human systems, and well-being. Because soils offer a substantial, transient storage for rainwater. Extreme rainfall events or the abrupt discharge of rainfall over a brief period of time are the two main causes of flash floods is due to global warming. They produce raging torrents of water that travel very quickly and happen between minutes to hours of a severe rainfall storm. Central and eastern North America, central and southern Europe, the Mediterranean region (covering southern Europe, northern Africa, and the Near East), western and central Asia, and southern Africa are predicted to experience the strongest global warming of hot extremes (medium confidence). Since interannual temperature variability is lowest in the tropics, where the number of extraordinarily hot days is predicted to rise the most, intense heatwaves are predicted to appear there first and become widespread at 1.5°C global warming (high confidence).

Environmental Problems, such as Pollution in the river are :

=> The main causes of water pollution in the Ganga river are the disposal of human sewage and animal waste, increasing population density, and disposal of industrial waste into the river.

=> Some of the dams being constructed along the Ganges basin will submerge substantial areas of nearby forest.

Social problems:

1. The Ganga Action plan (GAP) largely ignored public participation despite having funds allocated for it. It is interesting to note, therefore, that the NGRBP has made provisions for public participation although it has not yet outlined how it is to be implemented .

Latitude, longitude and topography are three terms that identify the geographic location of features and boundaries on earth, such as natural or constructed features, oceans, and more.

Latitude, Longitude, and Elevation are the three main terms used to describe geographic location. Longitude is the angular distance of a location east or west of the Prime Meridian, while latitude is the angular distance of a location north or south of the equator.

Latitude and longitude work as a pair to create a coordinate system that can pinpoint the exact location of any point on the surface of the Earth.

Elevation, which is used to describe the height of mountains, valleys, and other physical features, is the height above sea level. Geographers and other specialists can produce maps and models that precisely depict the features and boundaries of the Earth's surface by combining latitude, longitude and elevation.
