Question

What happens to Earth's atmosphere?

1) It blends into outer space
2) It ends abruptly at 30 km altitude
3) It ends abruptly at 50 km altitude
4) It ends abruptly at the moon

Answer 1

The Earth's atmosphere consists of several layers including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere does not end abruptly at any specific point but gradually thins out as altitude increases and eventually merges into outer space.

Step-by-step explanation:

The Earth's atmosphere consists of several layers including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer, extending up to about 10 kilometers in altitude, and is where most human activities occur. The stratosphere extends from 10 kilometers to about 50 kilometers and is primarily cold and free of clouds.

The mesosphere starts above the stratosphere and extends to 85 kilometers, where meteors burn up. The thermosphere starts above the mesosphere and extends to 600 kilometers, and this is where auroras and satellites occur. Above 100 kilometers, the atmosphere becomes very thin, and orbiting satellites can pass through it with little friction.

The atmosphere does not end abruptly at any specific point. It gradually thins out as altitude increases and eventually merges into outer space.
