Erosion and Deposition
Forces ______________ and _____________ Earth’s surfaces
Natural Forces move and deposit sediments



The ______________________________________ was formed by the movement of water
Water flowed over the land and carried away weather rock and soil
This shaped a valley where water flowed creating the canyon
Erosion and Deposition
 __________________- weathered particles are picked up and moved to a new place

__________________- the part of the erosion process in which sediment in placed
(__________________) in a new location
Gravity

Gravity is the force holding everything down on Earth
o This force causes water to move downward (think from the top of a mountain to the bottom)
o In the process it carries and deposits sediment in new places
Three types of Erosion

____________ erosion- rivers, streams carry sediment and deposit sediment at river bottom, floodplain,
and mouth of the river

____________ erosion- Strong winds life tiny particles of dust and carry them long distances

____________ erosion- As ice moves slowly it carries with it rock and soil particles frozen inside of the
ice
Valleys and Floodplains

As streams flow and carry sediment from the surface of the land they form valleys

___________________ - area of land on either side of the stream that is underwater when the stream
floods
Alluvial Fans and Deltas

Alluvial Fan- fan-shaped deposit of sediment at the base of a ______________________ formed from a
stream

Delta- an area of land formed by the buildup of sediment at the end (mouth) of a _______________
Sand Bars and Barrier Islands


Sandbar- a ridge of sand built up by the action of waves
Barrier Islands- a sandbar that builds up over time creates a long narrow island parallel to the coast
