Formation
Which rock forms when molten rock cools and hardens?
Igneous Rocks
What type of rock is basalt?
Igneous
(True/False) Weathering can be physical or chemical
True
What is one way sediments might be moved?
Water, wind, ice, gravity
What would happen if sediments are buried and compacted?
They become sedimentary rock
This type of rock is formed when tiny pieces of other rocks, minerals, and organic material settle in layers and are pressed together over long periods.
Sedimentary Rock
Name the 3 different rock types
Igneous, sedimentary, metamorphic
Name a physical way weathering can happen
Freezing, thawing, plant roots prying rocks apart.
How do glaciers cause erosion?
They can grind and transport huge amounts of rock
What happens if sedimentary rocks are pushed deep underground and melt together?
They become metamorphic rock
What rock is formed by heat and deep pressure inside the Earth?
Metamorphic Rock
Name a type of sedimentary rock
Sandstone or limestone
Name a chemical way that weathering can happen
Acid rain
How do rivers cause erosion?
By carrying sediments down stream
What happens if magma pushes through the surface of the Earth and cools?
It becomes igneous rock
Molten rock on the Earth's surface is called lava, but molten rock under the Earth's surface is called what?
Magma
Name a type of metamorphic rock
Slate or marble
What are the small pieces of rocks called once they have been broken down?
Sediments
What rock is commonly formed by weathering and erosion?
Sedimentary rocks
Why is the rock cycle a cycle?
Rocks are ever-changing and not permanent
Explain how sedimentary rocks are formed
They are formed when tiny pieces of other rocks, minerals, and organic material settle in layers and are pressed together.
When shale is changed deep within the Earth, what kind of rock does it turn into?
Slate
It is the process that breaks rock into smaller pieces.
What is erosion?
The movement of rock pieces by water, wind, ice, or gravity.
How is Earth's surface reshaped over time?
Through the rock cycle
