ROCKS AND ROCK CYCLE

What is the rock cycle?

• A process that describes the transformation of rocks through various geological processes, including igneous, sedimentary, and metamorphic formations.

• A method of classifying rocks based on their color and texture.

• A cycle that explains the formation of fossils in sedimentary rocks.

• A theory that states rocks are formed only from volcanic activity.

Define weathering in the context of the rock cycle.

• Weathering is the process of breaking down rocks into smaller particles through physical or chemical means.

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

• Weathering is the process of transporting sediments from one location to another.

• Weathering is the process of increasing the temperature of rocks to change their structure.

Differentiate between intrusive and extrusive igneous rocks.

• Intrusive igneous rocks form from lava that cools quickly on the surface, while extrusive igneous rocks form from magma that cools slowly beneath the Earth's surface.

• Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

• Both intrusive and extrusive igneous rocks form from magma that cools at different rates.

• Intrusive igneous rocks are formed from sediment, while extrusive igneous rocks are formed from volcanic ash.

What is igneous rock made from?

• Sedimentary layers compacted together

• Melting rock into magma and then cooling

• Metamorphic rock undergoing heat and pressure

• Organic materials decomposing over time

What is the significance of the rock cycle in geology?

• It explains how rocks are formed, broken down, and reformed, illustrating the dynamic nature of the Earth's crust.

• It describes the types of rocks found on Earth.

• It outlines the history of geological formations over millions of years.

• It provides a method for dating rocks and fossils.

How do metamorphic rocks form?

• They form from the cooling of magma.

• They form from existing rocks that undergo changes due to heat, pressure, or chemically active fluids.

• They form from the accumulation of sediments over time.

• They form from volcanic activity on the Earth's surface.

What is erosion and how does it relate to sedimentary rock formation?

• Erosion is the process of transporting weathered rock particles by wind, water, or ice, which contributes to the formation of sedimentary rock.

• Erosion is the process of breaking down rocks into smaller pieces without any transport.

• Erosion is the process of forming igneous rocks from molten lava.

• Erosion is the process of creating metamorphic rocks through heat and pressure.

What role does cementation play in the formation of sedimentary rocks?

• Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediment particles, binding them together.

• Cementation is the process of breaking down rocks into smaller particles through weathering.

• Cementation involves the transformation of sediment into metamorphic rock under heat and pressure.

• Cementation is the process of transporting sediment from one location to another by wind or water.

What are the three main types of rocks?

• Igneous, sedimentary, and metamorphic.

• Granite, limestone, and basalt.

• Clay, silt, and sand.

• Coal, oil, and natural gas.

Explain the term deposition in the rock cycle.

• Deposition is the process where sediments settle out of the transporting medium and accumulate in layers.

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

• Deposition is the process of transforming sediments into sedimentary rock through heat and pressure.

• Deposition is the process of moving sediments from one location to another.
