What is Pangea?
100
What pattern did we observe along plate boundary lines?
What are that earthquakes AND volcanoes occur along plate boundaries
100
What is an earthquake?
What is a sudden shaking in Earth's surface
200
What are the large sections of hard solid rock called?
What are plates
200
What objects did we compare the mantle to in class?
What is silly putty, milk, gum, play dough, frosting, and more!
200
Who is the Father of Plate Tectonics?
Who is Alfred Wegener
200
What do you call the plate boundary where two plates slide past one another?
What is a transform plate boundary
200
What is a trench?
a long, deep indentation in the ocean floor formed when two plates move together
300
What is underneath the ocean and underneath soil/vegetation on Earth?
What is the outer layer/crust
300
True or false: We can see the mantle from earth's surface.
What is false?
300
In the past, Africa used to be farther away from Europe than it is now. What could explain why Africa is closer to Europe now than it was before?
What are Africa and Europe are parts of different plates. The plates slowly moved toward each other as one plate went under the other plate into soft, solid rock over millions of years.
300
What plate boundary separates the South American plate and the African plate?
What is a divergent plate boundary
300
What landform is created at a divergent plate boundary and how do you describe it?
What is a mid-ocean ridge and what is an underwater mountain range
400
_________ are often found in the outer layer of earth and help scientists understand earth's past.
What are fossils?
400
What are convection currents?
What is a process of heating that takes place in the mantle, heat moves matter up, cools it off and it moves back down where it started.
400
On average, how slow are plates moving each year?
What is about 2-3.0 cm/year
400
What is the area called where one plate sinks underneath the other and is destroyed into the mantle?
What is a subduction zone?
400
What type of landform is only created at a transform boundary?
What is a fault
500
Why isn't the Earth getting bigger?
Why is the outer layer is being recycled into the mantle. At one end of a plate, the outer layer is being destroyed and at another end of the plate, new crust is forming from the mantle.
500
What causes plate motion?
What are convection currents in the mantle

How were the Himalayan Mountains formed?
What were two continents collided at a convergent plate boundary, creating a mountain range
