Types of Rocks
The three main types of rocks.
What is Igneous, Sedimentary, and Metamorphic.
A process in which rocks are created, changed, destroyed, and formed again.
What is the Rock Cycle.
The process by which rocks are broken down into smaller pieces
What is Weathering
The movement of sediments by wind, water, ice, or gravity.
What is erosion.
Which rock is known to float on water?
What is Pumice.
Rock that is formed from cooled magma or lava.
What is Igneous Rock.
Intense heat and pressure causes existing rocks to change in texture and mineral composition without melting. What part in the rock cycle is this?
What is changing into a metamorphic rock.
The process of sediments being pressed together
What is Compaction
What is it called when sediments settle in one area/location, forming a landform, such as a moraine.
What is deposition
This process happens over millions of years.
What is The Rock Cycle.
Rock type that is most likely to contain fossils.
What is Sedimentary Rock.
I am a sedimentary rock that is buried, then melted into magma, and then cooled. What type of rock did I become?
What is an igneous rock.
The rate at which magma or lava cools determines...
What is the size of crystals forming.
Iron reacts with oxygen in the air, forming iron oxide (rust). Is this an example of mechanical or chemical weathering?
What is chemical weathering?
This type of rock is the least commonly found on Earth
What is metamorphic rock
I am a rock that has a layered or banded appearance. What type of rock am I?
What is a foliated metamorphic rock.
Would the rock cycle speed up or slow down if weathering forces were absent on Earth?
The Rock Cycle would slow down.
Sedimentary rocks are broken down into sediments through...
What is weathering and erosion
This type of mechanical weathering happens when water enters cracks in rocks, freezes, and expands, causing the rock to break apart.
What is frost wedging.
This type of rock is the most abundant on Earth's surface.
What is sedimentary rock
A rock that cools slowly underground, forming larger crystals.
What is an intrusive igneous rock.
What force on Earth is created by the energy of the Sun that drives the formation of sediments?
When a volcano is erupting, what type of Igneous rock is being formed?
What is an extrusive igneous rok.
This type of triangular-shaped landform forms when a river deposits sediment into a slower-moving body of water, such as an ocean or lake.
What is a river delta.
This type of rock is the oldest on Earth
