The Kármán line, located at an altitude of 100 kilometers (62 miles) above sea level, is often considered the boundary where Earth's atmosphere ends and outer space begins. This is the point at which the atmosphere becomes too thin to support conventional flight and concepts of "air" and "space" lose their distinct meaning.

Is gravity a variable?
Gravity is a constant force that acts upon objects with mass, causing them to be attracted to each other. While the strength of gravity can vary based on the mass of the objects and their distance apart, it is not considered a variable in itself.
What 2 forces are acting on a falling object in the earths atmosphere?
The two main forces acting on a falling object in Earth's atmosphere are gravity, which pulls the object downward, and air resistance (also known as drag), which opposes the object's motion and slows it down as it falls.
How does gravity affect an object in motion?
Gravity affects an object in motion by pulling it towards the center of the Earth, causing it to accelerate downward. This acceleration can counteract other forces acting on the object, changing its velocity and trajectory. Gravity also affects the weight of the object, increasing it when moving against gravity and decreasing it when moving with gravity.
Which layer do light gases escape earths gravity?
Light gases such as hydrogen and helium can escape Earth's gravity at the exosphere, the outermost layer of the Earth's atmosphere. These gases have high enough kinetic energy to overcome Earth's gravitational pull and can gradually disperse into space.
A meteor is an asteroid that has been captured by a planet's or a moon's gravity and has been pulled away from the sun's gravity true or false?
False. A meteor is a small rocky or metallic body that enters a planet's atmosphere and burns up, creating a streak of light in the sky. It comes from a meteoroid, which is a smaller fragment of an asteroid or comet that has entered the Earth's atmosphere.
Which area marks boundary where earths atmosphere is constrained by gravity?
magnetosphere.
Which marks the boundary where earths atmosphere is constrained by gravity?
magnetosphere.
What is the size of the atmosphere?
Earths atmosphere? 300 miles. There is no definite boundary.
What is the the earths moons atmosphere?
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
The earths atmosphere came from where?
Gravity pulled it in.
What is the difference between the earths atmosphere and the earths gravity?
The two are completely unrelated.
What force holds the particles of air in earths atmosphere?
The Earth's gravity.
When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
What boundary in earths atmosphere blends with space?
Exosphere. The layers of the atmosphere are: Space Exosphere Thermosphere Mesosphere Stratosphere Troposphere Earth
What force holds the atmosphere to earths surface as it travels through space?
Gravity.
Why air pressure from earths atmosphere is not the cause of gravity?
Gravity is an entirely separate entity which is a consequence only of the mass of the earth itself. In fact, the atmosphere presses down because gravity is pulling on it.
What causes meteors to enter earths atmosphere?
Gravity. And the meteor is on a path that intersects the orbit of the Earth.
