Understanding Weathering and Erosion

What is weathering?

• The process of rocks moving from one place to another

• The breaking down of rocks into smaller pieces by natural forces

• The movement of tectonic plates

• The formation of igneous rocks

Which natural force is NOT involved in erosion?

• Wind

• Water

• Ice

• Fire

What are tectonic plates?

• Small pieces of rock that settle in new places

• Big pieces of the Earth's surface that move slowly

• Shapes and features on the Earth's surface

• Types of sedimentary rocks

What is the rock cycle?

• The process of rocks being moved by wind and water

• The never-ending process where rocks change from one type to another

• The movement of tectonic plates

• The breaking down of rocks into smaller pieces

What is sediment?

• Large rocks that form mountains

• Tiny pieces of rocks, sand, and dirt carried by wind or water

• A type of igneous rock

• A tectonic plate

How are igneous rocks formed?

• From the cooling and hardening of melted rock (magma)

• By the pressing of sediments over time

• By the movement of tectonic plates

• By the erosion of soil

What can tectonic plates cause when they bump into each other?

• Weathering

• Erosion

• Earthquakes and volcanoes

• Sedimentation

Which of the following is NOT a landform?

• Valley

• Hill

• Sediment

What happens during the rock cycle?

• Rocks are moved by wind and water

• Rocks change from one type to another over time

• Rocks are broken down into smaller pieces

• Rocks form tectonic plates

What is the main difference between weathering and erosion?

• Weathering involves movement, erosion does not

• Erosion involves movement, weathering does not

• Both involve the movement of rocks

• Both involve the breaking down of rocks
