In this picture, Where will the geologists find hard, solid rock?
C under 1 and 2 because the earth's entire outer layer is made of hard solid rock.
what is a cross section?
The cross section shows us what the inside looks like
This type of boundary pulls plates apart.
How did the same fossils end up on two different continents?
The plates moved very slowly over a long period of time

What is a trench?
a valley on the ocean floor where 2 plates meet
How is Earth's outer layer divided?
It is divided into plates
Earthquakes happen at which boundary types?
convergent and divergent
Which picture shows us what happens at convergent boundaries?
C One plate is going underneath the other plate and sinking into the soft rock below
if a planet has hard mantle will the plates move?
No, the plates need soft mantle to move
the place where 2 plates meet?
plate boundary
What happens to the plates at convergent boundaries?
one of the plates pushes down and sinks into the mantle
This boundary type separated the mesosaurus fossils over time?
Which picture describes what happens at divergent boundaries?
D Soft, solid rock from underneath the plates rose and hardened, adding solid rock to the edges of both plates.
true
What is a mid-ocean ridge?
A mid ocean ridge is an underwater mountain
What happens to the mantle at divergent plate boundaries?
the mantle rises up, cools down and creates new rock.
mid-ocean ridges
Patterns on this map show us?
volcanic activity and earthquakes happened in random locations all over the map.
