Which type of rock is formed from the cooling and solidification of magma or lava?

• Sedimentary

• Metamorphic

• Igneous

• Fossil

Identify the agent of erosion that is primarily responsible for creating sand dunes.

• Water

• Wind

• Ice

• Gravity

Explain how sedimentary rocks are formed.

• By the cooling of magma

• By the accumulation and compaction of sediments

• By the transformation of existing rock types

• By the melting of rocks

Which of the following is an example of chemical weathering?

• Frost wedging

• Oxidation

• Root growth

• Abrasion

Describe how human activities can accelerate the process of erosion.

• By planting more trees

• By constructing buildings and roads

• By conserving water

• By reducing pollution

What is the main difference between weathering and erosion?

• Weathering involves the movement of rocks, while erosion involves breaking them down.

• Weathering involves breaking down rocks, while erosion involves the movement of the broken pieces.

• Both involve the movement of rocks.

• Both involve breaking down rocks.

Construct an explanation of how metamorphic rocks are formed.

• By the cooling of magma

• By the accumulation of sediments

• By heat and pressure transforming existing rocks

• By the melting of rocks

How does the rock cycle illustrate the concept of conservation of matter?

• Rocks are destroyed and new matter is created.

• Rocks change form but the total amount of matter remains constant.

• Matter is lost during the transformation of rocks.

• New matter is added to the Earth through the rock cycle.

Develop a model to demonstrate how a river can change the landscape over time.

• By depositing sediments to form deltas

• By eroding mountains to form valleys

• By creating new rock formations

• By causing earthquakes
