Science

1. to predict future events or conditions, such as weather
4. weather: out-of-the-ordinary and extreme weather conditions
5. (O3) a form of oxygen that forms a thin layer in the stratosphere
6. Average weather in a given area over a long period of time
13. the layer of the atmosphere above the troposphere. The ozone layer is in the stratosphere.
14. the layer of the atmosphere that begins at Earth’s surface and extends upward for an average of 15 kilometers (km). Weather happens in the troposphere.
15. energy: energy of motion
18. a scientist who studies the weather
19. a cyclone or severe rotating tropical storm that produces high winds
20. a weather tool that measures air pressure

2. the layer of the atmosphere above the thermosphere. The exosphere marks the transition from the atmosphere to space.
3. the layer of the atmosphere above the mesosphere
7. pressure: the force exerted on a surface by the mass of the air above it; also called air pressure
8. the layer of gases surrounding Earth. Its layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere
9. the unit of measurement for air pressure.
10. a measure of how hot or cold the air is
11. the state of the atmosphere at a certain location
12. the scientific study of weather
16. when air moves from an area of high pressure to one of low pressure, making the air density equal
17. the layer of the atmosphere above the stratosphere
