What else can I help you with?
What is the speed to escape earths atmosphere?
Approximately 11.2 Kilometers per second, or about 33 times the speed of sound. However, at about 9000 kilometers above the earth, it is slightly less than 7.1 kps.
What causes the pressure of the atmosphere?
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Does the earths atmosphere extend about 1 kilometer above its surface?
No, the Earth's atmosphere extends much higher than 1 kilometer above its surface. The exosphere, the outermost layer of the atmosphere, extends up to 10,000 kilometers above the Earth's surface.
What is free atmosphere?
The free atmosphere refers to the layer of the Earth's atmosphere above the planetary boundary layer where air moves freely and is not influenced by the Earth's surface. It is typically above the lowest few kilometers of the atmosphere and is important for understanding atmospheric processes on a larger scale.
What is after exosphere?
The exosphere is the uppermost layer of the atmosphere. In the exosphere, an upward travelling molecule can escape to space if it is moving fast enough to attain escape velocity; otherwise it will be pulled back to the celestial body by gravity.
Which area marks boundary where earths atmosphere is constrained by gravity?
magnetosphere.
What layer of the earths atmosphere extends 17km above the earth?
stratosphere
What is the speed to escape earths atmosphere?

What is the difference between a plane and spacecraft?
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
How does gravity affect an object in motion?
it pulls the object towards the earth which kind of slows it down i guess. or is that friction? For an object travelling in the Earths atmosphere, or near to the Earth above the atmosphere, gravity provides a force pulling the object towards the centre of the Earth. Unless the object is travelling fast enough, what is called the escape velocity, this gravity force will ultimately cause the object to fall back to the surface. Friction is something else, the friction with the air in the atmosphere also slows the object, but this force acts in opposition to the direction of motion, not towards the Earths centre. To compute the trajectory of the object you need to take both forces into account.
Why is it important that the projectile in the last question be above the Earths atmosphere?
because of Air Ressistant
Can helium gas spread?
Yes, like most gasses it can spread within currents and mix in with other gases. It is lighter than air, so on earth it will rise above the heavier gases of nitrogen and oxygen that make up our atmosphere. It does appear in the earths atmosphere in trace quantities, but the majority will escape earths gravitation pull and dissipate into space.
Which marks the boundary where earths atmosphere is constrained by gravity?
magnetosphere.
What is the air above the earths surface called?
The layer of air above the Earth's surface is called the atmosphere. It is composed of various gases and extends several kilometers into space.
Why is the atmosphere above the surface of the earth?
The atmosphere is above the surface of the Earth because gravity pulls it towards the planet. The atmosphere contains gases that are essential for life, such as oxygen and nitrogen, and it helps regulate the planet's temperature by trapping heat from the sun.
What causes the pressure of the atmosphere?
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
What is the portion of the atmosphere 10 to 25 miles above the earths surface called?
Stratosphere by great usama
