Erosion - The process of moving sediment from one place to another

Caused by wind, water, or ice (sediment moves away)

Deposition - The process of dropping, or depositing, sediment in a new

location (sediment piles up or gets added)

Moraine - Formed from glacial debris (what glaciers picked up as they

moved)Made of rocks and soil

Glacial Valley - Formed by the movement of glaciers

Shaped like the letter “u”

Canyon - Deep, narrow valley located between rocky cliffs

Has steep sidesThe canyon carved by a river has the

shape of the letter “V”

River Valley - Caused by river erosionRiver carries sediment that wears away

the rockV-shaped

Sand Dune - Mound or hill made of sand

Found in deserts, near bodies of water, or at the foot of a mountain

Forms from wind causing sand to pile up

Sandbar - Ocean currents pick up sediments and carry the sediments a

short distance.Sediments are deposited. Deposits rise

gradually, forming a bar

Delta - Usually located where a river runs into a large body of water (such

as an ocean).Fan-shaped like the letter D.

In a river, water moves and causes the sediments it was carrying to be deposited. Sediments build up,

forming a delta.

Natural Bridge/Natural Arch - Geological formation where a rock

arch forms with an opening underneath.

May be formed by wind or water.

Stalagmites/Stalactites - Formed from minerals depositing on cave floors

(stalagmites) or cave ceilings (stalactites).
