6.10 B - Rock Cycle

This rock started as lava that cooled and then was heated and put under pressure over time. What type of rock is this?

• Sedimentar
• Igneous
• Metamorphic

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

This rock was found near the mouth of a volcano. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

Wind, water, and ice breaking down rock is called

• Erosion
• Deposition
• Compaction
• Weathering

Which type of rock results from melting and cooling of magma?

• Igneous
• Metamorphic
• Sedimentary
• Extrusive

Sedimentary rock can be changed into igneous rock if sediments are –

• compacted.
• deposited.
• weathered.
• melted.

Which of the following processes is one of the early steps in the formation of sedimentary rock?

• Weathering of existing rock
• Crystallization of molten minerals
• Melting of rock in volcanoes
• Chemical reactions that produce heat

The interlocking crystals of an igneous rock help to classify it since these crystals are evidence of how the rock formed. The crystals are a result of –

• quartz coming out of solution.
• particles forming layers.
• chemical reactions of minerals.
• melted rock that cooled.

Metamorphic rock forms where any kind of rock –

• is crystalized after being liquid rock.
• contains fossils of marine organisms
• is changed by the extreme heat and pressure.
• is composed of cemented sediment.

Which of the following is one of the final processes in the formation of sedimentary rock?

• Melting
• Cementation
• Flowing
• Separation
