The process where rocks from Earth's crust are slowly being broken into smaller pieces is called...
Weathering
100
What is the difference between weathering and erosion?
Weathering breaks rocks into smaller pieces; erosion moves those pieces away.

What causes magma beneath a volcano rise to the surface?

Constant Motion of the Tectonic Plates

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

What are the three Rapid landform changes we have talked about?

Volcanoes, Landslides, and Earthquakes.

200

What are the physical causes of weathering?

Water, ice, and wind.

200
The laying down of pieces of Earth's surface is called...
Deposition
200
Volcanic eruptions produce...
Rock , lava, and ash

What is the definition of a landslide?

Large amounts of land quickly sliding from high to low ground. 

200

What are our Slow landform changes?

Weathering, Erosion, and Deposition. 

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 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.
300
How are earthquakes caused?

The Constant motion of the tectonic Plates. 

300
What pulls all objects from higher places to lower places?
Gravity
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
Name 1 similarity and 1 difference between landslides and avalanches.
Both landslides and avalanches are rapid downhill movements due to gravity. Landslides are the movement of rock and soil, while avalanches are the movement of snow and ice.
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 are some causes of a landslide?

Gravity, Large quantities of water in the soil, lose of plants and trees that anchor the surrounding land, or local vibrations/earthquakes. 

400

List 5 different landforms.

Sample Answers: Plains, plateaus, mountains, peninsulas, valleys, canyons

500
Name the 2 types of weathering and how they are different.
Physical and chemical weathering. Physical weathering changes the size and physical appearance of rocks. Chemical weathering causes rocks to change into different materials.
500
Name and describe 3 ways to control erosion and deposition.
Plants - people can grow plants on hills so the roots keep the soil in place Terraces - slow the speed of water running downhill Barriers - block ocean waves from carrying the sand away
500

What is an effect of Volcanoes?

Creates new land, destroying surrounding areas, and spewing ash pollutes the air. 

500

What is an effect of an earthquake? 

Changing surface of the earth, rupturing the ground, and destroying surrounding buildings.

What comes first: weathering or erosion?
