Atmosphere Study Guide

James and Abigail are studying the Earth's atmosphere layers. During their research, they come across the thermosphere. What is the temperature trend in the thermosphere?

• The temperature trend in the thermosphere decreases with altitude.

• The temperature trend in the thermosphere fluctuates randomly with altitude.

• The temperature trend in the thermosphere is constant with altitude.

• The temperature trend in the thermosphere is an increase with altitude.

Abigail is studying the different layers of Earth's atmosphere for her science project. She wants to know: What is the temperature range in the thermosphere?

• 500 °C to 2,500 °C (932 °F to 4,532 °F)

• 0 °C to 500 °C (32 °F to 932 °F)
