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

This surface feature is most likely caused by the movement of the Earth's crustal plates. 

a) canyons       b) deltas      c)lakes      d)volcanoes

What are volcanoes

100

A large, slow moving mass of ice

What is a glacier

200
A rock made from heat and pressure cementing tiny pieces of broken down rock together (but not from melting)
What is: a sedimentary rock?
200
The removal of soil by gravity, wind, and running water
What is erosion?
200

The hottest layer. Made of solid metals

What is the inner core?

200
The instrument that measures vibrations of the Earth especially in an earthquake
What is a seismograph?
200

Scientists use these to provide information about life and conditions of the past. They are images left in rocks.

What are fossils?

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

This is the term used to describe when rock fragments are laid down in a new location.

What is deposition?

300

Which layer of the Earth is liquid? 

What is the outer core?

300
The type of boundary formed where two tectonic plates come together
What is a convergent boundary?
300

Fossils are usually found in this type of rock.

What is: sedimentary rock?

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

Melted rock before it exits a volcano.

What is magma?

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 and mountain ranges are formed

What is a convergent boundary?

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 change from one form to another and back again over many years
What is the rock cycle?
500

Thin inner core and outer core are both made up of these two metals. 

What is nickel and iron?

500
When the tectonic plates of the Earth slip or slide past each other horizontally, this boundary is formed.
What is a transform fault boundary?
500

Millions of years ago, there was only one super continent.

What is Pangaea?
