What happens when you step on loose rock or dirt?

What natural events can cause sediment to move?

Material that is moved by erosion.

The natural process by which natural forces move weathered rock and soil from one place to another.

The process by which transported materials are left in a new lactation.

The force that moves rock and other materials downhill.

Different types of movement; these include landslides, mudflows, slump, and creep.

Objective: Today you will learn about water erosion.

Starter: What happens when erosion occurs?

Do you know any major rivers or lakes in the area? Where are they located? Where does the water come from?

Water that moves over Earth’s surface.

Tiny grooves in soil.

A large groove or channel in soil that carries runoff after a rain storm.

A channel along which water is continually flowing down a slope.

The ability to do work or cause change.

The flat wide area along a river.

A loop like bend in a river.

A meander that has been cutoff by the river.

A wide sloping deposit of sediment formed where a stream leaves a mountain.

A landform built from sediment from a runoff from the ocean or lakes.

The amount of sediment a river carries.

Objective: Today you will learn about waves and wind.

Starter: What happens when sediment is carried down the river.

How can you explain the sand and waves at the beach?

How do waves affect the beach?How do you think beaches form?

A part of the shore that sticks out into the ocean.

An area of wave washed sediment along a coast.

The process whereby beach material is gradually shifted laterally as a result of waves meeting the shore

A beach that projects like a finger into the water.

A deposit of wind-blown sand.

The process by which wind removes surface material.

Fine wind deposited sediment.

Objective: Today you will learn about glaciers.

Starter: What causes a beach to form?

Is there a difference between snow that has just fallen or snow that has been on the ground for a long time?

A large mass of ice that moves slowly over land.

A glacier that covers much of a continent.

Continental glaciers that have covered large parts of Earth’s surface.

A long narrow glacier that forms when snow and ice build up high in a mountain valley.

Rocks picked up when a glacier moves across the land.

A mix of sediments that a glacier deposits directly on the surface.

A ridge that forms when a till deposited at the edges of a glacier.

A small depression that forms when a chunk of ice is left in a glacial till.
