Rock Cycle Benchmark Practice

What is the rock cycle?

• The process of rocks breaking down into smaller pieces.

• The process of rocks changing from one type to another over time.

• The process of rocks forming from molten lava.

• The process of rocks being weathered and eroded by wind and water.

What is metamorphic rock and how is it formed?

• Metamorphic rock is formed from the cooling and solidification of molten lava.

• Metamorphic rock is formed from the compaction and cementation of sediment.

• Metamorphic rock is formed from the heat and pressure applied to existing rocks.

• Metamorphic rock is formed from the accumulation of organic remains.

What is the difference between foliated and nonfoliated metamorphic rocks?

• Foliated metamorphic rocks have a layered or banded appearance, while nonfoliated metamorphic rocks do not.

• Foliated metamorphic rocks are formed from the cooling and solidification of molten lava, while nonfoliated metamorphic rocks are formed from the compaction and cementation of sediment.

• Foliated metamorphic rocks are formed from the accumulation of organic remains, while nonfoliated metamorphic rocks are formed from the heat and pressure applied to existing rocks.

• Foliated metamorphic rocks are formed from the weathering and erosion of existing rocks, while nonfoliated metamorphic rocks are formed from the heat and pressure applied to existing rocks.

How is sedimentary rock formed?

• Sedimentary rock is formed from the cooling and solidification of molten lava.

• Sedimentary rock is formed from the compaction and cementation of sediment.

• Sedimentary rock is formed from the heat and pressure applied to existing rocks.

• Sedimentary rock is formed from the accumulation of organic remains.

What is weathering and how does it contribute to the rock cycle?

• Weathering is the process of rocks changing from one type to another over time.

• Weathering is the process of rocks breaking down into smaller pieces.

• Weathering is the process of rocks forming from molten lava.

• Weathering is the process of rocks being weathered and eroded by wind and water.

What is compaction in the context of the rock cycle?

• Compaction is the process of rocks changing from one type to another over time.

• Compaction is the process of rocks breaking down into smaller pieces.

• Compaction is the process of rocks forming from molten lava.

• Compaction is the process of sediment being squeezed and compressed to form sedimentary rock.

How are clastic sedimentary rocks formed?

• Clastic sedimentary rocks are formed from the cooling and solidification of molten lava.

• Clastic sedimentary rocks are formed from the compaction and cementation of sediment.

• Clastic sedimentary rocks are formed from the heat and pressure applied to existing rocks.

• Clastic sedimentary rocks are formed from the accumulation of organic remains.

How are chemical sedimentary rocks formed?

• Chemical sedimentary rocks are formed from the cooling and solidification of molten lava.

• Chemical sedimentary rocks are formed from the compaction and cementation of sediment.

• Chemical sedimentary rocks are formed from the heat and pressure applied to existing rocks.

• Chemical sedimentary rocks are formed from the precipitation of minerals from water.

How are organic sedimentary rocks formed?

• Organic sedimentary rocks are formed from the cooling and solidification of molten lava.

• Organic sedimentary rocks are formed from the compaction and cementation of sediment.

• Organic sedimentary rocks are formed from the heat and pressure applied to existing rocks.

• Organic sedimentary rocks are formed from the accumulation of organic remains.

What is igneous rock and how is it formed?

• Igneous rock is formed from the cooling and solidification of molten lava.

• Igneous rock is formed from the compaction and cementation of sediment.

• Igneous rock is formed from the heat and pressure applied to existing rocks.
