How many kilometers does the earth's atmosphere extend from the surface of the earth?

The Earth's atmosphere extends up to an altitude of approximately 1000 km (620 miles) from the Earth's surface. However, the majority of the atmosphere is concentrated in the lower region of the atmosphere, which extends up to an altitude of approximately 10-15 km (6-9 miles) above the Earth's surface. This region of the atmosphere, known as the troposphere, contains most of the Earth's weather and climate systems, as well as the majority of the air that we breathe. Above the troposphere, the atmosphere extends through several other layers, including the stratosphere, mesosphere, and thermosphere, before finally merging into outer space at an altitude of around 1000 km (620 miles).
