Weathering
Small pieces of broken or eroded rock
What is sediment?
This landform is the tallest mountain in the world! It was created by two plates of the Earth’s crust pushing together.
What is Mount Everest?
This process carries sediment and pieces of rock away from where it started.
What is erosion?
This water form falls from the sky, and as it runs along the ground, it picks up sediment and moves it.
What is rain?
Water gets into cracks and freezes, expanding them in this weathering event.
What is ice weathering?
True or false: Weathering occurs before erosion.
True
This landform in the American Southwest was created from weathering by a river. (it’s really big!)
What is the Grand Canyon?
True or false: Rivers can’t carry sediment very far, because rock sinks in water.
False
This material is carried by wind, and slowly pelts away at hard rock, making the rock smaller.
What is sand?
Sediments are tumbled around in the ocean until they land on the beach as this material.
What is sand?
This cycle happens every year, has four major parts, and can cause different kinds of erosion to happen with the changes it brings.
This landform is a huge sheet of ice that moves slowly and greatly changes the land it moves across.
What is a glacier?
This force helps naturally move sediment and other eroded material downhill.
What is gravity?
This material expands when it freezes, causing cracks in the earth to expand.
What is water/ice?
This quick event occurs when lots of loose dirt, mud, and rocks slide quickly down a slope.
What is a mudslide?
This kind of weathering happens when other materials beat down landforms and rock
These landforms are created by ocean waves beating against hard, tall rocks on coastlines.
What are cliffs?
This occurs when large groups of sediment are deposited at the end of a river
What is a buildup?
This repetitive motion happens along coastlines, and erodes cliffs and beaches.
What are ocean waves?
Sand and wind combine to erode these landforms
What are mountains?
This kind of weathering happens when chemical changes occur in rocks.
These landforms are created when sand or water erode holes or patches in rock, instead of weathering it evenly.
What are arches?
When an erosion process puts down sediment after picking it up.
What is deposit?
These winding bodies of water can carry sediment for miles, and weather rock continuously. One of these made the Grand Canyon.
What are rivers?
This event is caused by a sudden eruption of molten rock on the earth’s surface
What is a volcano/volcanic eruption?
