i don't know this answer sorry.
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.
It extends to 600-700 km above earth's surface
The atmosphere extends about 600 kilometers (373 miles) above the Earth's surface.
The atmosphere extends about 62 miles (100 kilometers) above Earth's surface.
Earth's atmosphere extends up to about 560 kilometers (350 miles) above the Earth's surface. The outermost layer, called the exosphere, gradually transitions into outer space.
troposphere
The atmosphere column extends about 621 miles (1,000 kilometers) above the Earth's surface. The atmosphere is divided into different layers based on temperature variations, with the troposphere being the layer closest to the Earth's surface and extending up to about 7 miles (11 kilometers) high.
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.
The exosphere is the outermost layer of Earth's atmosphere, extending up to 10,000 km above the surface. It is a very thin layer where the atmosphere transitions into space.
The troposphere, which is the lowest layer of the Earth's atmosphere, extends about 17 km above the Earth's surface. This layer is where most weather events and atmospheric phenomena occur.
The Troposphere extends up to about 8-15 kilometers above Earth's surface. The Stratosphere reaches up to about 50 kilometers. The Mesosphere extends up to about 85 kilometers. The Thermosphere extends up to about 600 kilometers.
The stratosphere is right above the troposphere, which is what we live in. The ozone layer exists within the stratosphere. It extends up to about 50km above the surface.
