1. What is the supercontinent named in the Theory of continental drift?
2. What is the force that makes magma in Earth’s mantle move, due to heating and cooling?
3. A) Which layer of the earth makes a tectonic plate that is rigid and can move?

B) Which layer of the earth is hot, viscous liquid that churns in one place?

1. A) What type of plate boundary occurs where two pieces of oceanic crust move apart?

B) What type of plate boundary occurs where a piece of oceanic crust moves into and

slidesunderneath a piece of continental crust?

C) What type of plate boundary occurs where two pieces of oceanic crust slide past each

other?

1. A) What type of plate boundary creates a fault or cliff?

B) What type of plate boundary creates a trench?

C) What type of plate boundary creates a mid-ocean ridge?

1. A) At which plate boundary is new ocean crust formed?

B) At which plate boundary is old ocean crust destroyed?

1. *Pick 1 plate boundary: Draw and label the crust, mantle, lithosphere, asthenosphere, draw arrows of movement, and label the ocean feature created.
2. A) Which ancient ocean used to exist between Gondwanaland and Laurasia?

B) Which ancient ocean was renamed the Pacific?

1. A) Which ocean was created when Gondwanaland broke apart?

4. What is an inlet area where salt water meets fresh water called?
5. What is a body of brackish water called?
6. What is brackish water?

Part 2: Ocean Floor

1. A) List the three horizontal ocean zones in order from beach to ocean.

B) List the three vertical ocean zones in order from shallow to deep.

1. Which ocean zone is closest to the shore?
2. A) Which ocean zone has an area of sunlight?

B) What is it called?

1. A) Which ocean zone is referred to as the “open ocean?”

B) Which ocean zone is referred to as the “ocean floor” or bottom of the ocean?

1. What are the physical features of the ocean called?
2. What are the two major regions of the ocean floor?
3. A) What type of ocean sediment is formed from the shells and skeletons of living

organisms?

B) What type of ocean sediment is formed from particles from outer space?

C) What type of ocean sediment is formed from the chemical processes in the seawater?

D) What type of ocean sediment is carried into the ocean from the land?

1. *Label the diagram of the ocean floor (see bellringer)

Part 3: Islands

1. What is a volcano that forms in the middle of a plate, where magma rises upward until it erupts on the sea floor?
2. *Explain how a hot spot creates an island chain.
3. What is formed when a piece of the mainland is broken off and separated by a body of water?
4. *Draw and label the 6 components of a barrier island.
5. A) What type of reef forms when an island sinks below sea level?

B) What type of reef forms along the coast or an island?

C) What type of reef is separated by land with a body of water?
