Across
- 2. the force that pulls you down and all other objects to the Earth.
- 5. layer farthest from Earth’s surface.
- 6. extends from the mesosphere to greater than 600 km above the Earth’s surface.
- 7. reaches Earth’s surface as pellets of ice. Starts small, and grows when it is lifted by an updraft. When it becomes too heavy hail falls.
- 8. a thin layer of gases that surround the Earth. Nitrogen, oxygen, argon, carbon dioxide, and water vapor.
- 11. causes stratospheric temperatures to increase with increasing altitude.
- 12. reaches Earth’s surface as a solid; frozen as crystals of water.
- 13. Cycle a natural process where water moves continues to move along oceans, land, and the atmosphere.
- 14. reaches the Earth’s surface as droplets of water.
Down
- 1. layer 15- 50 km above Earth’s surface. Upper portion contains the highest amount of ozone gas. Area with the most ozone gases is called the ozone layer.
- 3. the number of layers to the atmosphere.
- 4. extends to the stratosphere to about 85 km above the Earth’s surface.
- 9. layer closest to the Earth , 8-15 km, Greek for “change”, weather occurs after heat is radiated in this layer.
- 10. is water in liquid or solid form, that falls from the atmosphere.
