• water

  smoke

  helium

  oxygen

• nitrogen

  argon

  carbon dioxide

​Remember,
the earth’s major systems are the atmosphere, hydrosphere, biosphere, and geosphere interact. 

Multiple Choice

The atmosphere protects us from the suns harmful_____

• dust

• rain

• ultra violet rays

• helium

Multiple Choice

What is one way that the atmosphere interacts with the Earth's hydrosphere?

• Water from oceans evaporate into the atmosphere as water vapor, then condenses to form clouds. It then falls back onto the earth as rain or snow.

• The magma from volcanos hardens and creates molten rocks. The rocks then go through the process of weathering and erosion.

Multiple Choice

The atmosphere traps heat from the _____.

• sun
• volcanos

• clouds

• evaporation

Multiple Choice

Look at the picture. What spheres are interacting with each other?

• atmosphere and hydrosphere

• hydrosphere and geosphere

• biosphere and atmosphere

• geosphere and atmosphere

Multiple Choice

What spheres are interacting in this picture?

• hydrosphere,

  lavasphere

  chemisphere

• biosphere, atmosphere, and geosphere

• atmosphere and geosphere

Earth’s atmosphere is made up of five main layers that vary in density, temperature, wind speed, and chemical composition. The atmospheric pressure decreases as distance from Earth’s surface increases, although there is no definite boundary between the atmosphere and space. Earth’s atmosphere gets thinner the higher you go in altitude.

​

​The Atmosphere

The closest to Earth’s surface, is the densest, and is where all weather occurs.

​

​The Troposphere

The stratosphere is much colder and lower in pressure, and contains 90 percent of Earth’s ozone, which shields the surface from harmful ultraviolet radiation.

The Stratosphere

Troposphere

Stratosphere

Evaporation

This is where most meteors burn up instead of striking Earth. The air in this layer is absolutely not friendly for us, as it would be impossible to breathe in the mesosphere because of too low oxygen levels. Also, this layer of the atmosphere has the lowest temperature of all layers, and they drop down to -86.5° C.

​

The Mesosphere

Multiple Choice

In the mesosphere the meteors burn up...

• true

• false

Multiple Choice

The air quality in the mesosphere is the greatest and we can breath comfortably...

• false

• true

This is where the aurorae (beautiful display of lights) occur. This layer is under constant attack from the X-rays and UV radiation coming from the Sun and the space around us. Because of this, the temperatures in this layer can even reach 2,000° C!

​The Thermosphere

Dropdown

The thermosphere protects us from the UV rays. True or false? ​

The exosphere is the top layer of the atmosphere. These layers work together as a system protecting Earth from the vacuum of space.
