Weathering the rock
This type of weathering happens when rocks are broken down by physical forces like wind or water.
What is mechanical weathering?
This natural force moves sand, soil, and rocks, shaping the landscape.
What is wind?
When sediment settles and forms new land, this process is called...
What is deposition?
What force causes rocks to break and wear down?
What is weathering?
This is when rocks change into new substances due to chemicals, such as acid rain.
What is chemical weathering?
Water in rivers, lakes, and oceans can cause erosion. This type of water erosion is called...
What is river erosion?
This landform is created by deposition and looks like a fan-shaped area of land at the mouth of a river.
What is a delta?
What natural force is responsible for carrying away material during erosion?
What is gravity?
The process of rocks breaking into smaller pieces because of low temperature.
What is freezing?
This is the process of erosion when glaciers move large amounts of rock and sediment.
What is glacier erosion?
These large piles of sand are formed by wind deposition.
What are sand dunes?
What is the process called when water wears away the surface of rocks and soil over time?
What is erosion?
The rock cycle begins with weathering, which forms these small particles.
What are sediments?
This force can cause the erosion of coastlines, making cliffs and beaches.
What are ocean waves?
When rivers slow down, they deposit what kind of material on the land?
What is sediment?
What is the natural force that helps to create features like canyons and valleys by eroding the land over millions of years?
What is water erosion?
This type of weathering occurs when plants or roots break through rocks as they grow.
What is biological weathering?
This agent of erosion happens when gravity pulls material downhill.
What is gravity?
What is the process called when a river slows down, and the sediment it carries is dropped, eventually forming new landforms like deltas or floodplains?
What is deposition?
Which force of nature is responsible for causing mass movement, such as landslides or mudslides, which rapidly erode the land?
What is gravity?
