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).
