Rock Cycle 6th grade

What is the rock cycle?

• The rock cycle is the process by which rocks change into different types of rocks.

• The rock cycle is a method of classifying rocks based on their color.

• The rock cycle refers to the way rocks are formed from minerals in the earth's crust.

• The rock cycle is the process of erosion and sedimentation of rocks over time.

What causes metamorphic rocks to form?

• Metamorphic rocks are formed by volcanic activity.

• Metamorphic rocks are formed when heat and pressure cause buried rock to change into new rock.

• Metamorphic rocks are formed from the cooling of magma.

• Metamorphic rocks are formed by the erosion of sedimentary rocks.

What is magma?

• Molten rock located beneath the Earth's surface.

• A type of gas found in volcanoes.

• Solid rock that has cooled and hardened.

• Liquid water found underground.

What is lava?

• Lava is a type of rock formed from cooled magma.

• Lava is magma that has reached the Earth's surface.

• Lava is a gas released during volcanic eruptions.

• Lava is a liquid found in the Earth's core.

What is compaction in the context of sedimentary rock formation?

• The process of sediments being melted into magma.

• The process by which sediments are pressed together under pressure, reducing their volume.

• The process of sediments being transported by water or wind.

• The process of sediments being chemically altered into new minerals.

How do igneous rocks form?

• Igneous rocks form when magma or lava cools and hardens.

• Igneous rocks form from the compression of sediment over time.

• Igneous rocks are formed by the accumulation of organic materials.

• Igneous rocks are created through the process of metamorphism.

How does erosion differ from weathering?

• Erosion is the process of moving weathered material from one location to another, while weathering is the breaking down of rocks.

• Erosion is the breaking down of rocks, while weathering is the process of moving them.

• Erosion and weathering are the same processes that occur simultaneously.

• Erosion is the process of creating new rocks, while weathering is the process of destroying them.

What is the process by which igneous rocks are formed?

• The process of sedimentation and compaction

• The melting and cooling of lava and magma

• The transformation of existing rocks through heat and pressure

• The evaporation of water from mineral-rich solutions

What role does pressure play in the formation of metamorphic rocks?

• Pressure causes the minerals in the rock to realign and change, resulting in metamorphic rock.

• Pressure has no effect on the formation of rocks.

• Pressure only affects igneous rocks, not metamorphic rocks.

• Pressure causes rocks to break down into sediment.

What is weathering?

• The process of erosion caused by human activity.

• The process by which wind and water change rocks and the Earth's surfaces.

• The process of plant growth breaking down rocks.

• The process of volcanic activity shaping the landscape.
