Rock Type Identification

What process is used to form sedimentary rocks?

• Lava cools and hardens to form a rock.
• Bits of sand and gravel form layers that turn into rock from pressure.
• Extreme heat and pressure from inside the Earth turn rocks into new rocks.
• Magma trapped under the Earth's surface cools and solidifies.

What material is used to form igneous rocks?

• magma
• sand
• gravel
• fossils

What process is used to form metamorphic rocks?

• Lava cools and hardens to form a rock.
• Bits of sand and gravel form layers that turn into rock from pressure.
• Extreme heat and pressure from inside the Earth turn rocks into new rocks.

Which type of rock would you expect to find by a volcano?

• Ingenious
• Igneous
• Indigenous 
• Indigo 

The process by which metamorphic rocks are formed...

• heat and pressure
• compaction and cementation
• melting and cooling

This rock was formed when magma cooled very slowly inside the Earth. What specific type of rock is it?

• Intrusive Igneous Rock
• Extrusive Igneous Rock
• Foliated Metamorphic Rock
• Clastic Sedimentary Rock

This rock formed when lava cooled very quickly on Earth's surface. What specific type of rock is it?

• Extrusive Igneous Rock
• Intrusive Igneous Rock
• Non-Foliated Metamorphic Rock
• Biochemical Sedimentary Rock

Which processes form sedimentary rocks?

• Lava cools and hardens to form a rock.

• Weathering, Erosion, Deposition, Compaction, Cementation

• Extreme heat and pressure from inside the Earth turn rocks into new rocks.

• Magma trapped under the Earth's surface cools and solidifies.

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

This rock started as molten magma. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic
