Question

air, atmospheric pressure, and weather
description of the atmosphere
composition: the atmosphere is composed of 78% nitrogen and 21% oxygen. the rest of the gases make up 1%.
regions: the atmosphere is divided into regions according to composition or temperature.

• the atmospheres composition consists of two main regions: homosphere and heterosphere. the homosphere extends from the earths surface up to an altitude of 60 miles. the heterosphere starts at 60 miles.
• the more common atmospheric classification is made according to temperature. the lowest layer of this thermal structure is the troposphere.
• the temperature within the troposphere decreases at a fairly constant rate as altitude increases. this decrease in temperature is called the temperature lapse rate. most of our weather occurs within the troposphere.

fill in the blank.

Explanation:

Step1: Find answer for question 2

Refer to text about atmosphere regions.
The two main regions are homosphere and heterosphere.

Step2: Find answer for question 3

Refer to text about homosphere's altitude range.
The homosphere extends from Earth's surface to 60 miles.

Step3: Find answer for question 4

Refer to text about weather - occurrence layer.
Most weather occurs in troposphere.

Step4: Find answer for question 5

Refer to text about temperature change in troposphere.
The decrease is called temperature lapse rate.
