Atmospheric Sciences

There is a troposphere which hold most oxygen, carbon dioxide, and other things. The Earth's atmosphere has all of those things which keep it under control. :)

Edit : Here's 4 things: 1) Oxygen, which many living things need.

2) Water which gives rain. Water is essential to life as we know it and rain helps to distribute water.

3) Ozone layer reduces harmful radiation from the Sun.

4) Natural "greenhouse effect" keeps the planet's average temperature above the freezing point of water.

It does not. Or perhaps I should say, you have the causal direction wrong. Life as we know it evolved here, on Earth, under Earth conditions. It's not a miracle that Earthly life developed under Earthly conditions; we could hardly expect Earth-type life to develop on alien planets, or alien life to develop here. We mould our environment, and our environment moulds us.

If we look at other planets or other locations, we're likely to discover totally different and alien kinds of life that evolved THERE, suited to THOSE conditions.

the atmosphere contains oxygen and other gases that you and other living things need to survive.

Yes, astronomers have discovered hundreds if not thousands of other galaxies.

The angel of the sunlight determine how much they heat up the earth. The axel of the earth is tilted 23.5 degrees in relation ship to the sun. This is what gives us the different seasons. When the angel is wide a specific amount of sunlight will be spread out over a big area and each part is only heated up a little. When the angel is narrow the same amount of sunlight is concentrated on a smaller area and that area is heated up much more.

Water on Earth's landmasses is distributed through various sources such as rivers, lakes, groundwater, and glaciers. However, it is not distributed equally, with some regions experiencing water scarcity while others have abundant water resources. Factors like climate, topography, and human activities influence the distribution of water on land.

Carbon dioxide is a greenhouse gas that absorbs and traps heat in Earth's atmosphere, contributing to the greenhouse effect. As the concentration of carbon dioxide in the atmosphere increases, it leads to an increase in atmospheric temperature, resulting in global warming and climate change.

Trapping too much infrared radiation can lead to the greenhouse effect, causing Earth's temperature to increase. This can result in climate change, with consequences such as rising sea levels, extreme weather events, and disruption of ecosystems.

Precipitation typically forms along both warm and cold fronts. Along a warm front, precipitation is usually light and steady, while along a cold front, precipitation is often more intense and short-lived.

The Earth would be extremely unlikely to leave its orbit naturally. It would require a very large external force, such as a collision with a massive celestial body, to disrupt its orbital path significantly. This scenario is highly improbable given the stable nature of the Earth's orbit around the sun.

Plants need water to grow. Plants also need sunlight to grow. They get water from the natural rain fall or if they are taken care of it is provided by there owner. The sunlight is natural though some light can be provided from the lights inside of the home.

Land and ocean ecosystems are connected through various mechanisms. For example, rivers and streams flow from land into the ocean, carrying nutrients and sediment that can impact marine life. Similarly, migratory species travel between land and ocean habitats, serving as a link between these ecosystems. Human activities on land, such as pollution and deforestation, can also have direct impacts on the health of ocean ecosystems through runoff and climate change.

Over 99% of the mass of the earth's atmosphere is contained in two layers: the troposphere and the stratosphere. Most of the earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the earth's weather occurs, is within about 12 km (7 miles) of the earth's surface.

The atmospheric pressure of 1.0 millibars is typically found at an altitude of about 50 kilometers above the Earth's surface. At this height, the pressure is very low, and it is considered to be part of the upper atmosphere or exosphere.

Carbon fossils can be found in sedimentary rocks such as shale, limestone, and sandstone. These rocks contain organic remains that have been preserved over millions of years, eventually forming into fossil fuels like coal, oil, and natural gas. These deposits are typically found in areas where there was once abundant plant and animal life, such as ancient forests or shallow seas.

We know about the inside of the Earth through seismic waves, which are waves generated by earthquakes. These waves travel through the Earth and can be detected and measured by seismographs on the surface. By analyzing how these waves behave and interact with different materials inside the Earth, scientists can infer the composition and structure of the Earth's interior.

Pressure is equal to force per unit area. It is calculated by dividing the force applied to an object by the area over which the force is distributed. This relationship is described by the formula P = F/A, where P is pressure, F is force, and A is area.

Clouds that have nimbo or nimbus in their names, like cumulonimbus (associated with thunderstorms).

Cumulonimbus clouds typically form with unstable atmospheric conditions. These clouds are associated with thunderstorms, heavy rainfall, and sometimes severe weather like hail and tornadoes. They have a towering appearance with a flat anvil top.

The jet stream is a high-altitude, fast-moving air current that flows from west to east in a wavy pattern in the atmosphere. There are polar and subtropical jet streams located in the upper levels of the troposphere, typically between 6 to 9 miles above the Earth's surface.

As you rise up through the layers of the atmosphere, both the density and pressure decrease. This is because there are fewer air molecules at higher altitudes, leading to lower density and pressure.

In the troposphere, temperature generally decreases as altitude increases. This is due to the decreasing air pressure and the fact that the upper regions of the troposphere are cooler due to their distance from the Earth's surface.

Carbon dioxide levels in the atmosphere in 1993 were around 360 ppm (parts per million). Levels now (2013) are approaching 400 ppm.

The Cirque is the name given to the bowl shaped depression were the valley glaciers usually begins. A glacier basically refers to a terminus that usually ends in a body of water.

The atmosphere has different layers due to variations in temperature and composition at different altitudes. These layers are named based on these differences, such as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer plays a unique role in Earth's atmospheric processes.
