Question

The depth of the atmosphere is commonly accepted as being ____."

Option 1: 100 kilometers
Option 2: 50 kilometers
Option 3: 200 kilometers
Option 4: 20 kilometers

Answer 1

The depth of Earth's atmosphere is commonly accepted as being around 100 kilometers (option 1), with several layers including the troposphere, stratosphere, and others extending above this point.

Step-by-step explanation:

The depth of Earth's atmosphere is commonly accepted as being approximately 100 kilometers thick. This measurement accounts for the various layers including the troposphere, stratosphere, mesosphere, thermosphere, and the exosphere. Each layer plays a crucial role in sustaining life, regulating temperature, and protecting the planet from space phenomena.



The troposphere, which extends up to about 12 km, is where most of our weather occurs, while the stratosphere continues up to about 50 km. Although some definitions consider the edge of space, or the Kármán line, to be at 100 km, the atmosphere technically continues well beyond this point, though it becomes increasingly thin with altitude.
