What is the definition of weathering?
Weathering is the breaking down of rocks.
100
What is erosion?
Erosion is the movement of rocks/dirt
100
Which layer of the Earth is the thinnest?
The crust
100
What is the definition of an Earthquake?
A sudden shake or shock of the Earth
100
What is the definition of a volcano?
A volcano is a mountain that opens downward into a pool of molten rock/magma.
200
What is the definition of physical weathering?
Physical weathering means that rocks get broken down into smaller pieces but don't change properties.
200
What is deposition?
Deposition is where rocks/dirt are deposited or dropped off after being moved by erosion.
200
Which layer of the Earth is the thickest?
The mantle
200
What are tectonic plates?
Tectonic plates are moving plates on Earth's crust.
200
What is the difference between magma and lava?
Magma is underground and lava is on the surface.
300
What is the definition of chemical weathering?
Chemical weathering is when rocks break down and their properties do change.
300
What is mass movement erosion caused by?
Gravity
300
Which layer of the Earth has the hottest temperature?
The inner core
300
What is the fault?
The fault is where the plates rub against each other.
300
Would a volcano that explodes quickly have thick or runny lava?
It would have thick lava.
400
What are the four types of physical weathering?
Ice wedging, plant growth, thermal expansion, and abrasion
400
What are the three types of ice weathering?
Horn, moraine, and U-Shaped
400
Which layer of the Earth is made up of liquid iron and nickel?
The Outer Core
400
What is the focus?
The focus is the exact spot where an earthquake starts.
400
Would a volcano that explodes quietly have thick or runny lava?
It would have runny lava.
500
What are the three main types of chemical weathering?
Oxidation, carbonation, and acid rain
500
What are the three types of mass movement erosion?
Slump, landslide, and creep
500
Which layer of the Earth is where Earthquakes are generally caused?
The Crust
500
What is the purpose of the Richter Scale?
The Richter Scale is the scale that measures the magnitude of an earthquake.
500
What is the "Ring of Fire"?
The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
