Rock Cycle Review

Refer to the Rock Cycle diagram. What statement best describes a process that occurs in the rock cycle?

• Metamorphic can form due to deposition and burial of sediments

• Sedimentary rock can become igneous rock and metamorphic rock

• Igneous rock can form when metamorphism of the rock occurs

• Sedimentary rock can form when it is melted down into magma

A rock formed beneath a lake and contains fossils of aquatic animals. Over time, this rock is forced into the mantle due to plate movement and melts. As the melted magma cuts through rock layers, it cools and crystallizes below the surface. Which change in rock type has occurred?

• Igneous rock has turned into sedimentary rock

• Sedimentary rock has turned into metamorphic rock

• Sedimentary rock has turned into igneous rock

• Metamorphic rock has turned into sedimentary rock

What type of rock is formed due to cooling and crystallization?

• Parent/Bed rock

• Igneous rock

• Metamorphic rock

• Sedimentary rock

Which statement best describes how sedimentary rock is formed?

• Flowing magma cooled quickly, creating many crystals.

• Extreme pressure melted and formed minerals in uneven layers.

• Layers of mineral deposits were compressed and cemented over time.

• Separate layers of lava cooled over time, hardening at different rates.

Which is labeled correctly

• 1-Igneous Rock, 2-Sedimentary Rock, 3-Sediments,

  4-Metamorphic Rock

• 1-Metamorphic Rock, 2-Igneous Rock, 3-Sediments,

  4-Sedimentary Rock

• 1-Sedimentary Rock, 2-Metamorphic Rock, 3-Igneous Rock,

  4-Sediments

• 1-Sediments, 2-Metamorphic Rock, 3-Igneous Rock,

  4-Sedimentary Rock

What forces can change sedimentary rock into metamorphic rock?

• Heat and pressure

• Weathering and erosion

• Compaction and cementation

• Rapid cooling and crystallization

Chemical weathering occurs whenever rocks are broken down and chemically altered. Which statement would BEST describe chemical weathering?

• Lichen growing on rocks can produce acid that reacts with the rock and helps to break down the rock to form soil

• Water freezing and thawing causing the rock to break down into smaller pieces and help form soil

• Scraping of rocks due to friction between rocks and moving particles in ocean waves

• Roots of a plants growing in the side of a mountain breaks down rocks into smaller pieces helping to create soil

Look at the diagram. Permeability is determined by the soil's texture. Which type of soil would be LEAST permeable?

• Gravel

• Sand

• Silt

• Clay

Soil that is permeable allows water to flow through it easily. The texture of the soil determines the permeability. Which statement about the texture of soil and permeability is correct?

• Smaller the particles the higher the permeability

• Smaller the particles the lower the permeability

• Larger the particles the lower the permeability

• Particle size does not affect the permeability

Look at the picture of this cave. What erosion agent MOST likely caused the formation of this cave?

• Sandblasting due to the wind blowing sand

• Water freezing and then thawing causing the cracks in the cliff

• Water from the ocean wearing away the cliff

• Pressure caused by two plate moving together
