Wildcard
100
The outermost layer of the earth. Made up of loose materials like rocks, soil, and seabed.
What is the crust?
100
Solid sections of rock that float on earth's molten mantle.
What are tectonic plates?
100
Earthquakes are an example of this type of change (slow/rapid)
What is a rapid change.
100
Weathering is this type of change (slow/rapid.)
What is slow?
100
A landslide is an example of this type of process (slow/rapid)
What is rapid?
200
This layer makes-up about 85% of earth's mass.
What is the mantle?
200
When plates diverge, they do this.
What is separate?
200
This is what magma is called when it reaches earth's surface.
What is lava?
200
This kind of weathering breaks down materials with acid.
What is chemical weathering?
200
This layer of the earth consists of super-heated molten lava made up of iron and nickle.
What is the outer core?
300
The innermost layer of the earth.
What is the inner core?
300
When plates come together, they do this.
What is transform?
300
These occur when tectonic plates rub against one another.
What are earthquakes?
300
This kind of weathering breaks down materials through forces like friction.
What is physical weathering?
300
The super continent that once existed on earth.
What is Pangaea?
400
The first 50 miles of this layer are hard rock, the next 150 miles are molten rock.
What is the mantle?
400
This is a word that we use to describe when plates rub against one another.
What is converge?
400
Volcanoes occur when this bursts out of earth's crust.
What is magma?
400
This process moves materials that have been broken down through weathering.
What is erosion?
400
Another name for physical weathering.
What is mechanical weathering?
500
Because of extremely high pressure, the iron and minerals that make-up this layer of the earth cannot melt.
What is the inner core?
500
This happens when plates push together and one gets submerged.
What is mountains form?
500
This state was created by volcanoes.
What is Hawaii?
500
The type of physical weathering caused by two objects rubbing up against one another.
What is abrasion?
500
When and earthquake occurs under the sea, it sometimes causes this to happen.
What is a tsunami?
