Warm Up—3 minutes Is it True (T) or False (F)? Correct the false statements to make them true! % of the Earth’s atmosphere is Oxygen – T or F 2. The layer of the atmosphere known as the troposphere is closest to the Earth’s surface – T or F 3. Liquid water has been found on Mars – T or F 4. Asteroids are known as ‘dirty snowballs’ – T or F 5. Meteors do not burn up in the Earth’s atmosphere and they land on the Earth’s surface.

Warm Up—3 minutes % of the Earth’s atmosphere is Oxygen – False oxygen is only 21% 2. The layer of the atmosphere known as the troposphere is closest to the Earth’s surface – True 3. Liquid water has been found on Mars – False scientist believe Mars shows evidence of ice crystals 4. Asteroids are known as ‘dirty snowballs’ – False comets 5. Meteors do not burn up in the Earth’s atmosphere and they land on the Earth’s surface. False meteorites do not burn up and crash into the Earth

Complete your Atmosphere Diagram

5 Atmospheric Layers: Troposphere: closest to the ground, where all weather happens (clouds found here) Stratosphere: ozone layer, where airplanes fly Mesosphere: where meteors/rock fragments burn up Thermosphere: where northern lights ‘Auroras’ occur Exosphere: where spacecraft/satellites orbit, upper limit of Earth’s atmosphere WRITE IN NOTEBOOK

3. Earth contains liquid water Only planet in solar system to contain liquid water Liquid water is essential for life to exist If we were closer to the sun, our oceans would boil away while if we were farther away, our oceans would freeze WRITE IN NOTEBOOK

Besides Earth, scientists would be most likely to find life on Mars because they have evidence of ice crystals!
