Deposition is the process in which sediment is laid down in new locations.

Gravity is the force that moves objects downward.
Page 7

Water Erosion
Lesson 2
Page 11
Runoff is water that flows over the ground surface carrying particles with it.
Page 12
As runoff travels, it forms tiny grooves in the soil called rills.
Page 13
A gully is a large groove, or channel, in the soil that carries runoff after a rainstorm.
Page 14
A stream is a channel along which water is continually flowing down a slope.
Page 15
A tributary is a stream or river that flows into a larger river.
Page 16
A flood plain is the flat, wide area of land along a river.

A meander is a loop-like bend in the course of a river.
Page 18
An oxbow lake is a meander that has been cut off from the river.

A landform made of sediment that is deposited where a river flows into an ocean or lake is called a delta.
Page 20
An alluvial fan is a wide, sloping deposit of sediment formed where a stream leaves a mountain range.
Page 21
Groundwater is water that fills the cracks and spaces in underground soil and rock layers.
Page 22
A deposit that hangs like an icicle from the roof of a cave is known as a stalactite.
Page 23
A stalagmite is a columnlike form that grows upward from the floor of a cavern.
Page 24
Karst topography is a region in which a layer of limestone close to the surface creates deep valleys, caverns, and sinkholes.

Glacial Erosion
Lesson 3
Page 27
A glacier is any large mass of ice that moves slowly over land.
Page 28
A continental glacier is a glacier that covers much of a continent or large island.
Page 29
Times in Earth’s history during which glaciers covered large parts of the surface are called ice ages.
Page 30
A valley glacier is a long, narrow glacier that forms when snow and ice build up high in a mountain valley.
Page 31
Plucking is the process by which a glacier picks up rocks as it flows over the land.
Page 32
The mixture of sediments that a glacier deposits directly on the surface is called till.
Page 33
A ridge formed by the till deposited at the edge of a glacier is a moraine.
Page 34
A kettle is a small depression that forms when a chunk of ice is left in glacial till.

Wave Erosion
Lesson 4
Page 37
A headland is a part of the shore that sticks out into the ocean.
Page 38
A beach is an area of wave-washed sediment along a coast.
Page 39
Longshore drift is the movement of water and sediment down a beach caused by waves coming in to shore at an angle.
Page 40
A spit is a beach that projects like a finger out into the water.

Wind Erosion
Lesson 5
Page 43
Deflation is the process by which wind removes surface materials.
Page 44
A sand dune is a deposit of wind-blown sand.
Page 45
Loess is a wind-formed deposit made of fine particles of clay and silt.
