## What is the edge of the atmosphere?

Kármán line
The Kármán line is the boundary between the Earth’s atmosphere and outer space. The Karman line lies at an altitude of 100 kilometres (62 mi) above the Earth’s sea level.

Where does Earth’s atmosphere end and space begin?

Earth ends and outer space starts at the Kármán line, some 62 miles (100 kilometers) above the planet’s surface.

How high is the edge of Earth’s atmosphere?

If you want to talk REAL outer space, the kind where Earth’s atmosphere gives way to the wind of particles blowing from the sun, that’s much farther out. The outermost layer of the atmosphere, the exosphere, pretty much ends at 6,200 miles (10,000 km) — 100 times beyond the Kármán Line.

### How far away is space in feet?

International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above Earth’s mean sea level.

How far up is the atmosphere?

Earth’s atmosphere stretches from the surface of the planet up to as far as 10,000 kilometers (6,214 miles) above. After that, the atmosphere blends into space.

## What is the hottest and coldest layer of the atmosphere?

The MESOSPHERE is the coldest layer and the THERMOSPHERE is the hottest layer in the atmosphere.

What is the highest layer of the atmosphere?

The exosphere is the highest layer of the atmosphere. It extends up to 10,000 km (6,200 miles; 33,000,000 ft.) above the Earth. Satellites orbit the Earth in the exosphere. The atmosphere in this layer is extremely thin and atoms and molecules of air are constantly escaping into outer space.

What is the bottom layer of the atmosphere called?

Earth’s atmosphere consists of a number of layers that differ in properties such as composition, temperature and pressure. The lowest layer is the troposphere, which extends from the surface to the bottom of the stratosphere.

### What are the four layers of the atmosphere in order?

In order from lowest to highest, the following are the four major layers of the atmosphere: In order from lowest to highest, the following are the four major layers of the atmosphere: the troposphere, stratosphere, mesosphere, and thermosphere.
