The gravitational attraction of the Earth pulls the atoms of the atmosphere towards the center of the Earth. The Law of Gravitation shows that the closer the atoms of the atmospheric gases are to Earth the more strongly thy are pulled "down". The atmospheric gases are also subject to other physical laws which make them want to diffuse into any low pressure area (like space).
As consequence the closer the gases are to Earth the more the balance between diffusion and gravity shifts towards the influence of gravity. As an outcome the concentration of gases closer to the Earth are higher than those further away (higher up). This concentration is called pressure. So the concentration gradient means that the atmospheric presure is less the higher you go.
It is essential: no gravity - no atmosphere.
Gravity does not directly affect hurricanes. Hurricanes are driven by a combination of atmospheric conditions such as temperature, humidity, and wind patterns. However, gravity does play a role in maintaining the structure of Earth's atmosphere, which can influence the behavior of hurricanes indirectly.
Gravity plays a role in determining climate by influencing the distribution of heat across the Earth's surface. It affects the circulation of the atmosphere and oceans, which in turn impact weather patterns and climate systems. Gravity also helps regulate the movement of water vapor in the atmosphere, which is important for cloud formation and precipitation.
Gravity plays the central role; without gravity, there would be no such thing as an orbit.
False. The presence of gravity does not directly affect the amount of gas in an atmosphere. Factors such as temperature, pressure, and chemical reactions play a larger role in determining the composition and amount of gas in a given atmosphere.
The Earth's gravity is what prevents the atmosphere from escaping into space. Gravity pulls gases in the atmosphere towards the Earth's surface, keeping the majority of the air close to our planet. Additionally, effects like the Earth's magnetic field also play a role in protecting the atmosphere from solar wind erosion.
Gravity is the force that keeps galaxies and solar systems together.
It makes it spherical.
A crucial role. Without gravity, matter would never have gathered together, to form galaxies and stars.
It pulls the soil downward.
That's what causes them to move.
it pushes things down
