NGSS 8 Earth Science

igneous rock is best defined as

• Rock that forms on the surface of the earth.

• Molten rock once it has reached the surface of the earth.

• Rock that is formed by the cooling or lava or magma.

• Molten rock that does not reach the earths surface.

What type of rock can you find fossils in?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

Series of natural processes by which rocks are slowly

changed from one kind of a rock to another.

• igneous rock

• metamorphic rock

• sedimentary rock

• rock cycle

Erosion is...

• materials begin moved across the Earth's surface by water and wind
• materials deposited into a new location as sediment
• rocks and other materials being broken down both physically and chemically

Metamorphic rocks made after experiencing

• Wind and erosion

• Water evaporating

• Heat and pressure

• Rapid cooling

Metamorphic rocks are...

• Composed of lava or magma that has cooled to form a solid rock

• Composed of rocks that have been changed by heat and/or pressure

• Composed of small particles called sediments

If you melt a rock/mineral and then let the magma/lava cool, you end with...?

• Igneous rock

• Metamorphic rock

• Sedimentary rock

• Chemical rock

If you heat and pressure any rock/mineral, it will change into...?

• Igneous Rock

• Sedimentary Rock

• Detrital Rock

• Metamorphic Rock

An igneous rock containing large crystals is most likely a(n)

• Chemical Rock
• Foliated Rock
• Extrusive Rock
• Intrusive Rock

The three groups of rocks are classified by

• How they form
• Color
• Grain size
• Chemical Composition
