Gas molecules in the atmosphere are pulled toward the earth by what?
Gas molecules in the atmosphere are pulled toward the Earth by gravity. This force keeps the gas molecules close to the Earth's surface and prevents them from floating off into space.
What pulls gas molecules in the atmosphere toward the Earth?
Gravity is the force that pulls gas molecules in the atmosphere towards the Earth. The Earth's mass creates a gravitational pull that acts on all objects, including gas molecules, causing them to be attracted towards the Earth's surface.
What would earth's atmospheric pressure be if earth's atmosphere contained twice as many molecules as is does today?
If Earth's atmosphere contained twice as many molecules as it does today, the atmospheric pressure would also double. This is because pressure is directly related to the number of gas molecules in the atmosphere.
Which of these events happens first in Earth's polar regions A Denser water sinks B Water travels as a deep current C Water molecules move closer together D Cold air chills water molecules?
Cold air chills water molecules happens first in Earth's polar regions.
Molecules of hydrogen escape from earth but molecules of oxygen and nitrogen are held to the surface why?
Hydrogen molecules are very light and have high velocities, which allows them to reach escape velocity and escape Earth's gravitational pull. On the other hand, oxygen and nitrogen molecules are heavier and have lower velocities, so they are more likely to be retained by Earth's gravity and stay within the atmosphere. Additionally, the interactions and composition of Earth's atmosphere play a role in retaining oxygen and nitrogen compared to hydrogen.
