Earth materials consisting of small, solid pieces of material that come from rocks or the remains of organisms is called sediment .

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

Gravity

is the force that moves objects downward.

Mass movement is any one of several processes by which gravity moves sediment downhill.

Lesson 2

Runoff

is water that flows over the ground surface carrying particles with it.

As runoff travels, it forms tiny grooves in the soil called

rills

.

A

gully

is a large groove, or channel, in the soil that carries runoff after a rainstorm.

A

stream

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

A

tributary

is a stream or river that flows into a larger river.

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.

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 .

An alluvial fan is a wide, sloping deposit of sediment formed where a stream leaves a mountain range.

Groundwater

is water that fills the cracks and spaces in underground soil and rock layers.

A deposit that hangs like an icicle from the roof of a cave is known as a

stalactite

.

A

stalagmite

is a columnlike form that grows upward from the floor of a cavern.

Karst topography

is a region in which a layer of limestone close to the surface creates deep valleys, caverns, and sinkholes.

Lesson 3

A glacier is any large mass of ice that moves slowly over land.

A continental glacier is a glacier that covers much of a continent or large island.

Times in Earth’s history during which glaciers covered large parts of the surface are called ice ages .

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

Plucking is the process by which a glacier picks up rocks as it flows over the land.

The mixture of sediments that a glacier deposits directly on the surface is called till .

A ridge formed by the till deposited at the edge of a glacier is a moraine .

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

Good luck

Lesson 4

A headland is a part of the shore that sticks out into the ocean.

A beach is an area of wave-washed sediment along a coast.

Longshore drift is the movement of water and sediment down a beach caused by waves coming in to shore at an angle.

A spit is a beach that projects like a finger out into the water.

Lesson 5

Deflation is the process by which wind removes surface materials.

A sand dune blown sand.

is a deposit of wind-

Loess is a wind-formed deposit made of fine particles of clay and silt.
