What type of activity do the triangles and circles represent?
Volcanoes and earthquakes!

Earth's outer layer is divided into sections called ___________.
Plates!
400
Which of the following diagrams illustrate a divergent plate boundary?
400
What is the Earth's outer layer made of underneath the image shown?
Hard, solid rock
400
What is Earth’s outer layer like underneath the surface in the image?
Hard, solid rock under both the land and ocean!

At ______________ plate boundaries, rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.
Divergent!
600
What type of plate boundary is illustrated by this diagram?
Convergent plate boundary
600
The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years. What kind of boundary must be between these plates?
Divergent plate boundary!
600
In the past, Africa used to be farther away from Europe than it is now (shown above). What could explain why Africa is closer to Europe now than it was before?
Convergent plate motion. The plates slowly moved toward each other as one plate went under the other plate into soft, solid rock over millions of years.
600
At _____________ plate boundaries, one plate moves underneath the other plate and sinks into the mantle.
Convergent!
800

What type of plate motion would cause these fossils to end up on different continents?
Divergent plate motion. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years!

What type of landform is created after the plate motion pictured in the diagram?
A trench!
1000
What type of landform is created after the plate motion pictured in the diagram?

Does this map indicate that in this area there may be divergent plate motion, convergent plate motion, or either?
Either! Volcanoes and earthquakes can be found near either divergent or convergent plate boundaries.
