What is needed for a sedimentary rock to change into a metamorphic rock
Heat and Pressure

The process by which sediment moves away because of water, gravity, wind, or ice
Erosion

List three types of natural hazards
Volcanoes, earthquakes, tsunamis

What is a glacier
A huge area of slow moving ice
200
What are three types of rock?
Igneous, metamorphic and sedimentary.
200
The process by which sediment comes to rest?
Deposition
200
What is a cause of volcanoes?
Earthquakes and landslides
200
What is a V-shaped valley?
A valley carved by a stream or river.
300
Which type of rock forms from sediment compacting?
Sedimentary Rock

What is weathering?
The process that breaks down rocks
300

400
Which type of rock forms from heat and pressure?
Metamorphic Rock
400
What are the types of weathering?
Wind, water, and ice

How does a volcano form?
Volcanoes are fromed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts (lava). Over time as the volcano continues to erupt, it will get bigger and bigger.

What is the difference between magma and lava?
Mamga is in the volcano, and lava is what erupts out of the volcano.
500
How is igneous rock formed?
By cooling lava

Using this picture, describe what is happening using vocabulary words (weathering, erosion and deposition)
Wind and rain breaks down the rock (Weathering)
The rain and wind carries the rock away (erosion) and deposits it at the bottom (deposition)

What can you do at school to protect yourself from an earthquake?
Get under something sturdy, cover your head and hang onto what ever you are under.

What is the difference between erosion and weathering?
Weathering is the break down of rocks, erosion is the movement of rocks.
