Social studies grade 6 space unit 1 lesson 1

Which planet has an atmosphere?

• Mars

• Earth

• Venus

• Moon

Earth's atmosphere includes:

• Nitrogen 78%

• Oxygen 21%

• Argon 0.9%

• Carbon dioxide 0.03%

• Water 0.01%

Scientist compare Earth to the rocky planets that are part of the solar system:

• Mars

• Moon

• Black hole

• Venus

The atmosphere is about:

• 300 miles(480km)

• 200 miles(204km)

• 336 miles(490km)

• 100 miles(55km)

The atmosphere meets outer space at an imaginary line called:

• Carbon line

• Oxygen line

• Nitrogen

• Karman line

The earth's atmosphere is made up of different layers.

• True

• False

• I don't know

• I don't remember

Troposphere is:

• Closest layer, contains half of the atmosphere, clouds water vapor and dust occur here

• Farthest layer, contains all of the atmosphere, clouds water vapor and dust don't occur here

• Dry layer

• Wet layer

Stratosphere is:

• Very dry, balloon airs and jets fly here

• Very wet, airplanes fly here

• Very big

• Closest layer to earth

Mesosphere is:

• highest layer

• Hottest layer

• Coldest layer

• Oldest layer

Thermosphere is:

• has alot of air

• air density=no air, we think of it as outer space, space shuttles orbit Earth here

• air density=low, we normally think of it as outer space, space shuttles orbit Earth here

• air density=high, we don't think of it as outer space, space shuttles don't orbit Earth here
