Which of the following statements best describes how metamorphic rock is formed?

• High temperature and intense pressure may transform an igneous rock into a metamorphic rock with banded layers.

• Low temperature and intense pressure may transform a sedimentary rock into a metamorphic rock with banded layers.

• High temperature and low pressure from Earth's core may transform an igneous rock into a metamorphic rock with banded layers.

• Low temperature and low pressure may transform an igneous rock into a metamorphic rock with banded layers.

Which statement best describes the relationship between igneous and metamorphic rocks?

• Igneous rocks must go through the sedimentary process to change into metamorphic rocks.

• Igneous rocks are chemically changed into metamorphic rocks because of high temperature and pressure.

• Metamorphic rocks are formed from melting igneous rocks.

• Metamorphic rocks and igneous rocks do not follow a rock cycle.

Magma (the molten rock present deep inside the earth) or lava on earth's surface following a volcanic eruption, solidifies due to rapid cooling and crystallizes to form a type of rock called ​ (a)   .

• igneous rocks

• metamorphic rocks

• sedimentary rocks

Obsidian

Weathering

Metamorphic

Sedimentary

Igneous

Granite

Deposition

Sediment

Jasmine created the following flow chart about sedimentary rock. Flow Chart Where did Jasmine make a mistake?

• Weathering of rock material must occur after erosion takes place.

• Deposition must occur before sediment is cemented.

• Compaction must occur before sediment is deposited and cemented together.

• Erosion of weathered sediment must occur after compaction.

Which of the following situations best describes the chemical weathering process of sedimentary rock?

• Sedimentary sandstone is carried away by water along the bedrock of a stream.

• Sedimentary sandstone allows water to freeze and thaw inside its cracks.

• Sedimentary limestone cliffs are battered by strong ocean waves.

• Sedimentary limestone is exposed to acid rain at the top of a mountain.

This rock formed when bits of other rocks became pressed into a solid. What type of rock is it?

• Sedimentary Rock

• Metamorphic Rock

• Igneous Rock

When sediments are pressed together tightly, this is called ____________.

• Compaction

• Cementation

• Weathering

• Erosion
