Answers
1
Why would there be fossils of sea creatures in a desert?
Some sea creatures used to be able to survive in the desert.
Wind and weathering carried the fossils to the desert.
The desert was an ocean floor millions of years ago.
Someone brought the fossils to the desert.

9
Why did most scientists reject Wegener’s theory?
He couldn't explain the force that was causing the continents to move.
He was a young and unknown scientist at the time.
He did not have any evidence to support his theory.
He had other theories that had been discredited in the past.
10

Crust
11
Which of the following are characteristics of oceanic crust?
d. Oceanic crust is the oldest crust.
a. Oceanic crust is mostly watery granite.
b. Oceanic crust is what makes up the silicon beaches.
c. Oceanic crust is mostly basalt and comprises the ocean floor.
12
3. Which of the following are characteristics of continental crust?
a. Continental crust is mostly granite and makes up the land we live on.
b. Continental crust is what makes up the ocean floor.
c. Continental crust is mostly basalt.
d. Continental crust has the greatest density of all types of crust.
13
What happens in a subduction zone?
Two plates slide past each other and cause earthquakes.
Two plates of different densities come together, causing one to sink & melt

The different volumes of each layer cause them to separate and layer.
The different composition of each layer causes them to separate and layer.
The different masses of each layer cause them to separate and layer.
