11 Jun FLVS SCIENCE 101 – Plate Tectonics – Continental Drift

Question
2.01 Plate Tectonics

A. Plate Tectonics

B. Continental Drift

C. Convection

D. Mantle

E. Core

1. _______ Causes the layer of Earth under the crust to move

2. _______ The source of Earth’s internal heat

3._________ The theory that combines our knowledge about continental movement over time with the movement of continental plates and seafloor spreading

4. ________ The theory that describes how all of the continents used to belong to one landmass but randomly moved over time

5. _________ The layer of Earth under the crust

2.02 Ocean Formation

Use the diagram to identify the structure described in each question.

1. Part of the continental plate that extends away from the coastline, where the water is relatively shallow

2. An underwater mountain with a pointed peak whose top is still submerged

3. A long and narrow opening in the crust, with steep sides, usually occurring above a subduction zone

4. The area where oceanic plates diverge, and new seafloor is created in the process of seafloor spreading

2.03 Ocean’s Impact on Weather

Choose an answer from each set of (a/b).

1. Carbon dioxide is (released/absorbed) by the ocean.

2. Coral Bleaching (increases/decreases) biodiversity of the (coral reef/polar region) food web.

3. Hurricanes can impact marine biodiversity by destroying sea turtle nests, which means (more/fewer) sea turtles surviving to adulthood and (more/fewer) food for the predators of sea turtle hatchlings.

4. Clouds can trap (heat/water droplets) close to the surface, causing temperatures to become warmer.

5. Wind occurs when air moves from regions of (higher/lower) pressure to regions of (higher/ lower) pressure. The greater the pressure difference, the (slower/ faster) the wind speed.

2.05 Ocean’s Impact on Climate

1. What gas is human activity releasing that is causing ocean temperatures to increase?

2. If human activity or natural activity (hurricanes) destroys a certain species, what consequence might this have on the environment?

3. Between ice and the ocean, which one absorbs the sun’s heat and which one reflects the sun’s heat?

4. How does melting ice slow down ocean currents

5. Where would the most significant change in ocean currents occur do to global warming?

2.06 Air and Sea Interactions

1. ____Water vapor in the air changes to liquid water

2. ____Occurs in plant root nodules

3. ____Food and dry leaves are broken down into simpler substances by bacteria and fungi

4. ____Breaking down organic nitrogen to ammonia

5. ____An increase in methane will affect this.

6. ____Water is returned to ground water storage

7. ____The process by which plants use oxygen to release stored energy

8. ____The conversion of nitrates into inorganic nitrogen gas.

9. ____Gases move from an area of high concentration to low concentration

10. ____Plants convert carbon dioxide to oxygen

A. Decomposition

B. Fixation (Nitrogen)

C. Condensation

D. Ammonification

E. Respiration

F. Infiltration

G. Carbon Cycle

H. Photosynthesis

I. Diffusion

J. Denitrification
