CKLA Unit 5 Chapter 6

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 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 plants growing in soil and stabilizing the ground.

• Erosion is the chemical breakdown of minerals in rocks due to acid rain.

• Erosion is the process of volcanic activity that creates new landforms.

What is weathering?

• Weathering is the breaking down of rocks into smaller pieces by natural processes.

• Weathering is the process of creating new rocks from minerals.

• Weathering is the movement of rocks from one place to another.

• Weathering is the process of heating rocks to form magma.

What is the main difference between sedimentary and igneous rocks?

• 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.

• Sedimentary rocks are formed from organic materials, while igneous rocks are formed from water.

What type of rock is formed from heat and pressure?

• Igneous rock

• Metamorphic rock

• Sedimentary rock

• Volcanic rock

What causes rocks to weather and erode?

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

• High temperatures and volcanic activity.

• Human activities such as mining and construction.

• Chemical reactions with metals in the rocks.

What is compaction in the context of sedimentary rocks?

• The process of breaking down rocks into smaller pieces.

• The process where sediments are pressed together under pressure, forming sedimentary rocks.

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

• The process of chemically altering minerals in rocks.

What is metamorphic rock?

• A type of rock formed from volcanic activity.

• A rock that is formed when existing rocks are changed by heat, pressure, or chemical processes.

• A sedimentary rock that has been compacted over time.

• A rock that is formed from the cooling of magma.

What is igneous rock?

• A type of rock formed from the cooling and solidification of magma or lava.

• A rock that is formed by the accumulation of sediments over time.

• A rock that is formed from the alteration of existing rocks due to heat and pressure.

• A type of rock that is formed from the evaporation of water in lakes and seas.

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.
