Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The stratosphere is the layer of the atmosphere where temperature increases with altitude, extending from about 10-15 kilometers to about 50 kilometers above the Earth's surface.

Multiple choice

What is the primary force responsible for atmospheric circulation?

  1. Pressure gradient force

  2. Coriolis force

  3. Centrifugal force

  4. Gravitational force
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The pressure gradient force is the primary force responsible for atmospheric circulation. It arises from the difference in air pressure between two points.

Multiple choice

Which molecule is considered a key indicator of the presence of an atmosphere on a planet?

  1. Oxygen

  2. Carbon dioxide

  3. Methane

  4. Water vapor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water vapor is considered a key indicator of the presence of an atmosphere on a planet because it is a stable molecule that can exist in both liquid and gaseous states under a wide range of temperatures and pressures.

Multiple choice

Which layer of the Earth is composed primarily of gases?

  1. Crust

  2. Mantle

  3. Outer Core

  4. Atmosphere
