As two continental plates move toward each other, what landforms would you expect to see?

1. As two continental plates move toward each other, what landforms would you expect to see? • Volcanoes • Cliffs • Mesas • Structural Mountains

2. D. Structural Mountains – correct - because 2 continental masses will push into each other and “crumple” the edges to form mountains

3. Where would you find the newest land on Earth? • In areas of continental convergence • In areas where two ocean plates come together • In areas where plates are moving apart • In areas where two plates are sliding past each other

4. C. In areas where plates are moving apart When plates move apart it is due to magma reaching the surface. When magma cools new land is formed.

5. 3. Which characteristics are used to classify stars? A. temperature B. brightness (magnitude) C. mass D. All of the above

6. A. temperature B. brightness (magnitude) C. mass D.All of the above

7. 4. If a star becomes a black hole at the end of its life, it is a? A. high mass star B. nebula C. low mass star D. All of the above

8. A.high mass star B. nebula C. low mass star D. All of the above

9. 5. Galaxies are classified based on their? A. composition B. color C. shape D. All of the above

10. A. composition B. color C. shape D. All of the above

11. 6. The moon rotates on its axis and revolves once around the Earth at the same rate which causes A. day and night B. the same side of the moon to always be visible from Earth C. the tides to change D. opposite sides of the moon to be visible from Earth

12. A. day and night B. the same side of the moon to always be visible from Earth C. the tides to change D. opposite sides of the moon to be visible from Earth

13. 7. The moon and the sun appear to move across the sky each day because of A. the Sun’s movement in the sky B. the Earth’s revolution around the sun C. the Earth’s rotation on its axis D. the Moon’s shadow on the Earth

14. A. the Sun’s movement in the sky B. the Earth’s revolution around the sun C. the Earth’s rotation on it’s axis D. the Moon’s shadow on the Earth

15. 8. How often do Spring tides and Neap tides each occur? A. two times a month B. two times a day C. two times a year D. four times a year http://co-ops.nos.noaa.gov/astronomical.shtml

16. A.two times a month B. two times a day C. two times a year D. four times a year http://co-ops.nos.noaa.gov/astronomical.shtml

17. Mangrove trees have special roots that let them live in the somewhat salty water where rivers meet the ocean. These roots collect sediments, debris, and mud. This gradually helps coastlines stretch farther into the sea. Forests of mangrove trees also provide shelter for wildlife. The high winds of hurricanes and typhoons often destroy mangrove forests. 9. The destruction of these forests most likely affects ecosystems by — A reducing beach erosion in sea-turtle nesting areas B reducing the amount of saltwater flowing into lakes C causing pollution in inland rivers and streams D forcing migratory birds to find other places to rest
