Geology Test Review

A

1

How are igneous rocks produced?

Melting and cooling 

-1

2

What are the three types of tectonic plate movements?

Divergent, convergent, transform

-5

3

Describe a divergent plate movement and give an example.

Plates move away from each other (mid Atlantic ridge)

+5

4

What is Pangea?

The supercontinent from before the continents all broke apart.

+4

5

Draw a diagram of the Earth's layers.

+4

B

1

Give three examples of rock and state which kind each are. 

Basalt (igneous), Granite (igneous), slate (metamorphic), etc

+2

2

How are sedimentary rocks produced?

Weathering and erosion

-2

3

What is the difference between a small scale geological process and a large scale geological process?

landslide vs plate motion 

-8

4

What are three features of the Earth's core?

Solid, hot, lots of pressure, etc

+3

5

What type of rock is the continental crust mostly made of?

Granite

+10

C

1

What is the difference between a slow scale geological process and a fast/catastrophic scale geological process? 

Plate motion vs volcano

-5

2

What are the layers in rocks called that scientists use to tell how old that part of the crust is?

Varves

-5

3

How are metamorphic rocks produced?

Heat and pressure

-3

4

What is the difference between magma and lava?

Magma is beneath the earth's crust and lava is on the surface. 

+3

5

Define a geological process.

Something that happens on the Earth's crust that impacts the way it is structured.

-3

D

1

At about what speed do the tectonic plates move?

About as fast as your fingernails grow. 

+5

2

What are three features of the Earth's mantle?

Liquid, hot, currents, etc

+1

3

What type of rock is the oceanic crust mostly made of?

Basalt

-10

4

What are the three types of rock?

Igneous, sedimentary, and metamorphic

-4

5

What are tectonic plates?

Large slabs of the Earth's crust that slowly move around.

+5

E

1

What are three features of the Earth's crust?

Continental crust - floats, buoyant, etc

Oceanic crust - dense, sinks, etc

+2

2

What are the two types of convergent plate movements? Describe both

Subduction - oceanic crust dives beneath continental

Collision - two continental crusts push against each other 

-1

3

Describe a transform plate movement and give an example. 

Two plates rub against each other (San Andreas Fault)

-2

4

What are the two different kinds of igneous rock? Explain how both are made. 

Intrusive - formed beneath the Earth's crust

Extrusive - formed on the surface of the Earth
