CKLA Unit 5 Chapter 6

What is cementation in the context of sedimentary rocks?

• The process of breaking down rocks into smaller particles.

• The process where dissolved minerals crystallize and bind sediments together to form sedimentary rocks.

• The process of transporting sediments from one location to another.

• The process of layering sediments over time to create sedimentary structures.

What are the three major classes of rocks?

• Igneous, sedimentary, and metamorphic

• Granite, limestone, and basalt

• Clay, silt, and sand

• Volcanic, plutonic, and sedimentary

What is sedimentary rock?

• Sedimentary rock is formed from the accumulation of sediments.

• Sedimentary rock is formed from volcanic activity.

• Sedimentary rock is formed from the cooling of magma.

• Sedimentary rock is formed from metamorphic processes.

What is the main difference between sedimentary and igneous rocks?

• Sedimentary rocks are formed from magma, while igneous rocks are formed from sediments.

• Sedimentary rocks are formed from sediments, while igneous rocks are formed from magma.

• Sedimentary rocks are formed from volcanic activity, while igneous rocks are formed from erosion.

• Sedimentary rocks are formed under high pressure, while igneous rocks are formed at the Earth's surface.

What is erosion?

• Erosion is the process by which rocks and soil are worn away and transported by natural forces like water, wind, or ice.

• Erosion is the process of planting trees to prevent soil loss.

• Erosion is the method of creating new landforms through volcanic activity.

• Erosion is the technique of using chemicals to break down rocks.

What is igneous rock?

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

• Igneous rock is formed from the compression of sediment over time.

• Igneous rock is formed from the metamorphosis of existing rocks.

• Igneous rock is formed from the evaporation of water in volcanic areas.

What is the rock cycle?

• The process of rocks being created, destroyed, and recreated.

• A method of classifying different types of rocks.

• The geological process of forming mountains.

• The cycle of erosion and sedimentation in rivers.

What is the role of pressure in rock formation?

• Pressure has no effect on rock formation.

• Pressure can lead to the formation of igneous rocks.

• Pressure can change the structure of rocks, leading to the formation of metamorphic rocks.

• Pressure only affects sedimentary rocks.

What causes rocks to weather and erode?

• Time and natural forces cause rocks to weather and erode.

• High temperatures and pressure from tectonic activity.

• Chemical reactions with minerals in the rocks.

• Human activities such as mining and construction.

What type of rock is formed from heat and pressure?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock
