• Metamorphic, sedimentary, deposition

• Sedimentary, weathering, igneous

• Igneous, sedimentary, metamorphic

• Lava, erosion, metamorphic

Which word means "melted rock inside the Earth"?

• Igneous

• Magma

• Lava

• Metamorphic

What forces cause a metamorphic rock to form?

• Heat and pressure

• Heat and erosion

• Pressure and weathering

• Blunt force and cooling

What process occurs just before deposition?

• Weathering

• Silting

• Morphing

• Erosion

Which of the following is a set of weathering agents?

• Thunder and snow

• Lightning and airplanes

• Ice and tree roots

• Wind and falling leaves

What is erosion?

• The breaking down of rocks into smaller pieces called sediments or clast

• The movement of rock pieces called sediments or clast from one place to another

• The placement of rock pieces called sediments or clast in a new location

A bone becomes buried deep underground and pressure squeezes out all the water inside it. Over time, minerals replace the water, causing the bone to harden into a fossil. The name of this process is:

• Impression

• Erosion

• Rock cycle

• Lithification

The word "loam" describes:

• Soil that is mostly sand

• Soil that is mostly silt

• Soil that is an equal mixture of sand and silt

• Soil that is a mixture of sand, silt, and clay

If you place your fingertips in a soil sample that is smooth and powdery, you are most likely feeling:

• Silt

• Sand

• Loam

• Clay
