Rock Cycle

Slate is a type of metamorphic rock that can be polished to have a solid, smooth surface. The process that metamorphic rocks undergo in nature make slate useful for various purposes. Manufacturers, for example, use slate for the surface of pool tables. Which processes of metamorphic rock make slate ideal for the use of countertops?

• a combination of sedimentation and heating forms planes of easy cleavage

• a combination of heat and pressure forms planes of easy cleavage

• a combination of melting and cooling forms surfaces with small pores

• a combination of weathering and erosion from surfaces with small pores

What drives the transformation from metamorphic rock to sedimentary rock

• cooling and hardening

• weathering and erosion

• high pressure and compacting

• high temperature and melting

The sand found along the Gulf of Mexico coast of Florida originated in granite formed from slowly cooling magma in the Appilachian Mountains. When this sand is burried and compacted, it will become sandstone. The sand stone may be moved deeper underground where it will be subjected to heat and pressure to become quartize. What is the rock cycle for this sequence?

• Igneous to metamorphic to sedimentary

• Metamorphic to igneous to sedimentary

• Igneous to sedimentary to metamorphic

• Metamorphic to sedimentary to igneous

Deforestation occurs when large areas of trees are cut down. Which of the following impacts on the environment would result from deforestation?

• Increased erosion

• colder temperatures

• decreased carbon dioxide

• greater oxygen production

In an area where a river has cut deep into the Earth's surface, several layers of different rock are exposed. Which of the following statements most likely describes the oldest rock layer?

• It is composed o0f igneous intrusive rock

• it contains the highest density of fossils

• It is the thickest layer

• it is below the other layer

Landscapes on earth are in a constant state of change. Some landscapes are sinking while others are being lifted up. Which of the following is usually true of hills in a region that is being uplifted faster than it is being eroded?

• They have steep slopes and slow moving streams

• They have gentle slopes and fast mocing streams

• They have steep slopes and fast moving streams

• They have gentle slopes and slow moving streams

Justin noticed several cracks in the sidewalk. Weeds are growing through them, causing the cracks to expand. What is this process?

• erosion

• sedimentation

• deposition

• weathering

over time small pieces of rock may be brought together by water, when the water evaporates, the sun will harden these rocks into a single layer of

• metamorphic rock

• sedimentary rock

• molten rock

• igneous rock

Small pieces of rock are also called

• sediment

• coal

• organic matter

• erosion

_{Sedimentary Rocks are often made up of other rocks and minerals.}

• True

• False
