Atmosphere of earth - why it isnt static?

In summary, the conversation discusses the motion of Earth's atmosphere and how it is connected to the Earth's rotation. The experts mention that friction and drag play a role in causing the atmosphere to move along with the Earth. They also mention other factors, such as temperature and pressure differentials, that contribute to the dynamic movement of the air and influence weather patterns.

Homework Statement


here is Earth and here is atmosphere. Why this atmosphere is going around with Earth when it is going around, not stay in one place static? i mean not this motion around sun but this motion which is making day and night, the air and everything else is going around with about 1000m/s speed (on equator), how it can be explained?

Friction, drag. If the air stayed in place and the Earth was spinning through it at 1000m/s (at the equator), things would be pretty "interesting" to say the least.

haha, would be nice wind;]
so it is connected with this "friction" and if this didnt exist on Earth all things would stay in one place while Earth would spin around?

Air is a fluid, and fluids are subject to friction and drag when they move at different speeds than solids with which they are in contact. There are lots of other things that cause the air to be dynamic, too, like differentials in temperature, density, and pressure. That causes our weather, and transports heat and water around our planet.
 

1. Why does the Earth's atmosphere change over time?

The Earth's atmosphere is constantly changing due to a variety of natural processes, such as volcanic eruptions, changes in solar activity, and the Earth's own orbit and rotation. Human activities, such as burning fossil fuels and deforestation, also contribute to changes in the atmosphere.

2. How does the Earth's atmosphere affect the weather?

The Earth's atmosphere plays a crucial role in determining the weather patterns on our planet. The atmosphere traps the Sun's heat, keeping the Earth warm enough to support life. It also helps to regulate the amount of moisture in the air, which influences precipitation and cloud formation. Changes in the atmosphere's composition can lead to extreme weather events, such as hurricanes and droughts.

3. What factors contribute to the Earth's dynamic atmosphere?

The Earth's atmosphere is influenced by several factors, including the Sun's energy, the Earth's rotation and tilt, and the composition of the atmosphere itself. The Earth's magnetic field also plays a role in shaping the atmosphere, as it deflects solar winds and protects the atmosphere from being stripped away into space.

4. How does the Earth's atmosphere interact with other systems on the planet?

The Earth's atmosphere is closely connected to other systems on the planet, such as the oceans, land, and biosphere. For example, the atmosphere and oceans work together to regulate the Earth's temperature through processes like evaporation and condensation. The atmosphere also provides essential gases, such as oxygen, for life on Earth to thrive.

5. Is the Earth's atmosphere always changing?

Yes, the Earth's atmosphere is constantly changing, both on short-term and long-term timescales. While some changes are natural and expected, others are a result of human activities, such as air pollution and climate change. It is important for scientists to continue monitoring and studying the Earth's atmosphere to better understand these changes and their potential impacts on our planet.
