3. Question 2 EarthquakesDroughts Volcanic eruptions Avalanche HurricanesRockslides TornadoesSinkholes FloodsHailstorms TsunamiMudslides Fires Blizzards

4. Question 3 A globe is a spherical model of the earth. A map shows the earth, or parts of it, on a flat surface.

5. Question 4 Clouds cover about 50% of the Earth’s surface.

6. Question 5 Meteorologists study the Earth’s atmosphere and monitor, study, and forecast the weather.

7. Question 6 A thermometer measures temperature.

8. Question 7 Anemometers measure wind speed and direction.

9. Question 8 Geologists study the history and structure of the Earth as recorded in rocks. Geologists examine how the crust bends and breaks under pressure.

10. Question 9 Seismologists study earthquakes, examine trenches for past earthquakes, and tudy earthquake waves.

11. Question 10 Volcanologists study volcanoes and the earth’s internal heat. They study active geysers, steam from cracks in earth’s surface, and lava.

12. Question 11 TIROS 1 was a weather satellite designed to see what the Earth looked like from space.

13. Question 12 A rocket will launch a weather satellite to a height (altitude) where the Earth’s gravitational force keeps it in orbit around the Earth.

14. Question 13 If a satellite orbits too fast it can escape Earth’s gravitational pull and zoom out into space. If a satellite orbits too slowly, gravity can pull it back to the Earth.

15. Question 14, 15, and 17 The two types of weather satellites are: GOES-Geostationary Orbiting Environmental Satellite POES-Polar Orbiting Environmental Satellite

16. Question 16 GOES satellites are located about 35,000 km above the Earth. They orbit over the equator in sync with the Earth’s rotation. They always are viewing the same area on the Earth.

17. Question 18 POES satellites are positioned about 850 km above the Earth. They have pole-to-pole orbits. Because the earth rotates but the orbit of a POES satellite does not change, it can look at different strips of the Earth as the Earth rotates beneath it.
