Describe 3 distinct criteria that scientist use to study the atmosphere. Hint: Read profile of the atmosphere in the textbook. Why does air pressure change with increasing altitude above Earth’s surface?

Ch3 Lab – Layers of the Atmosphere

Create a chart showing all the listed atmospheric layers. Include in the chart, the altitude range in kilometers, temperature range in Celsius and gases present in each layer. In an additional column, specifically list what you might find in each layer. Your chart should have 5 columns. You will have to do outside research to complete the chart thoroughly.
Heterosphere
Homosphere
Thermosphere
Mesosphere
Stratosphere
Troposhere
Ionosphere
Ozonosphere
In addition to the chart, answer/complete the following:
Describe 3 distinct criteria that scientist use to study the atmosphere. Hint: Read profile of the atmosphere in the textbook.
Why does air pressure change with increasing altitude above Earth’s surface?
Why does the height of the tropopause vary by latitude and throughout the year?
Which layer do you think is the most critical to humans and why?
