The three types of rocks
What are: 1. igneous rocks; 2. sedimentary rocks; 3. metamorphic rocks?
100
The breaking down of minerals and rocks into small pieces (sediments)
What is weathering?
100
Middle layer; the thickest layer of the Earth
What is the mantle?
100

The pieces of earth's crust (plates) float on top of the--

mantle

100
Scientists use these to provide information about life and conditions of the past.
What are: fossils?
200

Limestone (a rock made from cementing and compacting)

What is: (an example of) a sedimentary rock?

200
The removal of soil by gravity, wind, and running water
What is erosion?
200

The layer; made of liquid iron and nickel

What is the outer core?

200

The type of plate boundary we associate with earthquakes

What is a Transform boundary?

200

True or False:

Marine animal fossils can be found in Mountains.

What is: True?

300
A rock that has changed from one type of rock to another by heat or pressure; may also have a swirled look
What is a metamorphic rock?
300

What happens to make sediments become a sedimentary rock

Cementing and compacting

300
This increases as the depth beneath the surface of the Earth increases.
What is: pressure?
300
The type of boundary formed where two tectonic plates come together
What is a convergent boundary?
300

I plant trees to prevent this.

What is erosion?

400
Rocks that are usually found near volcanoes and are formed from the cooling and hardening of hot magma or lava
What are igneous rocks?
400

What happened to any Igneous Rock

Melted then cooled.

400
The 4 main layers of the Earth
What are: 1. crust; 2. mantle; 3. outer core; 4. inner core?
400
The type of boundary formed when tectonic plates move apart
What is a divergent boundary?
400

The way trenches, mid-ocean ridges, and mountain ranges are formed

What is plate tectonics?

500
The addition of these is needed over time for a sedimentary rock to be changed into a metamorphic rock.
What are: heat and pressure?
500

When rocks are dropped off and piled up at the end.

What is deposition?

500

This energy causes the movement of material within the Earth.

Convection Currents

500

The boundary where any two tectonic plates meet is known as a

What is a fault line?

500
Millions of years ago, there was only one super continent.
What is Pangaea?
