The process where rocks from Earth's crust are slowly being broken into smaller pieces is called...
Weathering
100
This is the process of water, ice, wind, and gravity moving pieces of rock or dirt from one place to another.
Erosion
100

Volcanic eruptions are an example of _________ changes to Earth's surface.


Fast

A break or crack in rocks where Earth's crust can move is called...
A fault

What are 3 of the 4 physical causes of weathering?
Water, ice, trees, and wind
200
The laying down of pieces of Earth's surface is called...
Deposition

What is the difference between lava and magma?


Magma is molten rock below earth's surface; lava is molten rock one it is above the earth's surface.

How do earthquakes happen?
Where two plates meet, they move back and forth against each other, or slide underneath or on top of another plate.
200
What pulls all objects from higher places to lower places?
Gravity
300
Explain how plants can weather a rock.
A plant's roots can grow inside a rock, and as they grow, it can break the rock apart.
300
Name 3 of the 4 ways weathered materials are moved.
Water, ice, gravity, and wind
300

What causes a volcano to erupt?  


The gases produced by the magma can no longer be contained and need a way to escape.

300
An earthquake is an example of a _______ change on Earth's surface.
Fast
300
Name some of the examples of fast changes to Earth's surface that we've discussed.
Volcanoes, earthquakes, landslides, tornado, flood, hurricane, wildfire, blizzard.
400
How can ice cause physical weathering?
If water gets into the crack of a rock and then freezes, it will expand when it turns into ice. The expanding ice can cause the rock to break into smaller pieces.
400

What is the difference between weathering and erosion?


Weathering breaks rocks into smaller pieces; erosion moves those pieces away.
400
What is the difference between an active and a dormant volcano?
Active volcano - erupts frequently Dormant volcano - a volcano that has not erupted for a long time
400
What can happen to Earth's surface after an earthquake?
Mountains, valleys, or bodies of water can form.
