Rocks and Weathering Quiz

What are the three main types of rocks?

• Limestone, shale, and sandstone

• Granite, marble, and quartz

• Igneous, sedimentary, and metamorphic

• Volcanic, tectonic, and seismic

How are sedimentary rocks formed?

• Deposition, compaction, and cementation of sediments

• Volcanic activity and cooling

• Erosion and weathering of igneous rocks

• Evaporation and crystallization of minerals

What is the process of turning igneous rocks into metamorphic rocks called?

• Weathering

• Metamorphism

• Erosion

• Volcanism

What is the difference between mechanical weathering and chemical weathering?

• Mechanical weathering is caused by temperature changes, while chemical weathering is caused by physical abrasion.

• Mechanical weathering occurs only in dry climates, while chemical weathering occurs only in humid climates.

• Mechanical weathering only affects sedimentary rocks, while chemical weathering only affects igneous rocks.

• Mechanical weathering physically breaks down rocks into smaller pieces, while chemical weathering changes the composition of the rocks through chemical reactions.

Give an example of a chemical weathering process.

• Oxidation of iron in rocks

• Combustion of wood

• Freezing of water

• Boiling of water

What are the characteristics of igneous rocks?

• Formation from cooling and solidification of magma or lava, crystalline structure, classification based on texture and mineral composition

• Classification based on color and size, formed from organic materials

• Formation from erosion and weathering of metamorphic rocks, glassy structure

• Formation from heating and pressure of sedimentary rocks, non-crystalline structure

How do metamorphic rocks differ from sedimentary rocks?

• Metamorphic rocks are formed from molten lava

• Metamorphic rocks are formed from organic remains

• Metamorphic rocks are formed from the accumulation of sediments

• Metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemical processes.

Explain the process of erosion and its impact on rocks.

• Erosion is the process of building up rocks and soil by the action of water, wind, or ice. It can impact rocks by making them stronger and more resistant to weathering.

• Erosion is the process of attracting rocks and soil by the action of water, wind, or ice. It can impact rocks by making them more attractive and valuable.

• Erosion is the process of wearing away rocks and soil by the action of water, wind, or ice. It can impact rocks by breaking them down into smaller pieces and carrying them away.

• Erosion is the process of creating new rocks and soil by the action of water, wind, or ice. It can impact rocks by making them larger and more stable.

What are the different types of weathering that can affect rocks?

• Biological weathering and nuclear weathering

• Physical weathering and emotional weathering

• Volcanic weathering and solar weathering

• The different types of weathering that can affect rocks are mechanical weathering and chemical weathering.

How do rocks contribute to the formation of soil?

• Deforestation

• Industrial pollution

• Volcanic eruptions

• Weathering and erosion
