The Atmosphere: Lower Layers of the Atmosphere

The video explains the structure and characteristics of the troposphere and stratosphere, highlighting the role of the Earth's surface in heating the troposphere and the temperature gradient with altitude. It discusses the tropopause as a boundary and the stratosphere's features, including jet streams and their impact on weather. The importance of the ozone layer in absorbing harmful UV radiation and its vulnerability to pollutants is also covered.

What is the primary reason temperatures decrease as you move away from the Earth's surface in the troposphere?

• The influence of the sun's rays

• The presence of clouds

• The Earth's surface heats the troposphere

• The rotation of the Earth

At what altitude does the tropopause separate the troposphere from the stratosphere?

• 6 to 8 kilometers

• 17 kilometers

• 50 kilometers

• 12 kilometers

What is the typical temperature in the stratosphere?

• 25 degrees Celsius

• Minus 60 degrees Celsius

• 0 degrees Celsius

• 18 degrees Celsius

How do jet streams in the stratosphere affect airplanes?

• They cause turbulence

• They help planes arrive sooner

• They have no effect on planes

• They slow down the planes

Why is the ozone layer crucial for life on Earth?

• It provides oxygen

• It creates weather patterns

• It absorbs ultraviolet radiation

• It reflects sunlight
