Question 1: What are the types of plate boundaries?

Answer:

• divergent

• convergent

• transform

Question 2: What do plates do that produce changes in Earth?

Answer:

-collide -pull apart -grind past each other

Question 3: Rift-valley

Answer:

a deep valley on land that forms along a divergent boundary.

Question 4: Faults

Answer:

breaks in Earth's crust where rocks have slipped past each other.Question 5: Describe what happens when: A plate carrying oceanic crust collides with a plate carrying continental crust

Answer:

The oceanic plate begins to sink and plunges beneath the continental plate.Question 6: Describe what happens when: Two plates carrying oceanic crust collide

Answer:

The plate that is more dense dives under the other plate and returns to the mantle.Question 7: Describe what happens when: Two plates carrying continental crust collide

Answer:

The plates crash head-on, forming mountain ranges from the collision.

Question 8: Plate tectonics

Answer:

the geological theory that states that pieces of Earth's crust are in constant, slow motion

Question 9: Transform boundary

Answer:

place where two plates slip past each other, moving in opposite directions.-earthquakes happen along transform boundaries

Question 10: A Canadian scientist who made the theory of plate tectonics

Answer:

• Tuzo Wilson

Question 11: plates

Answer:

sections of the lithosphere that slowly move over the asthenosphere, carrying pieces of continental and oceanic crust

Question 12: convergent boundary

Answer:

place where two plates come together, or converge.

Question 13: divergent boundary

Answer:

place where two plates move apart, or diverge.-rift-valleys form along divergent boundaries -most divergent boundaries occur at mid-ocean ridge

Question 14: What determines what plate sinks or comes out on top?

Answer:

density

Question 15: Explain what force caused the movement of the continents from one

super-continent to their present locations

Answer:

The convection currents under the asthenosphere push the seafloor along with the continental plates away from the mid-ocean ridges.

Question 16: Scientific theory

Answer:

A well-tested concept that explains a wide range of observations.

Question 17: What does the theory of plate tectonics explain?

Answer:

Explains the:

-formation -movement -subduction of Earth's plates
