Unit 1 Lesson 3 Flashcards
Sediment
Tiny grains of broken down 🪨
Erosion
The process by which sediment and other materials are moved from one place to another
Deposition
The process by which eroded material is dropped
Occurs when gravity’s pull on sediment is greater than the force of flowing water 💦 or wind 💨
Gradient
The measure of the change in elevation over a certain distance
(The steepness of a slope)
Load
Materials carried by a stream
( A stream that has large particles has a higher erosion rate)
Discharge
The amount of water a stream carries in a given amount of time
Floodplain
A flat area along a river that forms from sediments deposited when the river overflows
Usually very fertile ( good for planting)
Delta
A load of material deposited in a triangular or fan shape at the mouth of a river or stream
Alluvial fan
A fan-shaped load of material that forms on land
Groundwater
Water located within the rocks below earth’s surface
Shoreline
The place where land and water meet
Beach
An area of shoreline made up of material deposited by waves and currents
Sandbar
An underwater or exposed ridge of sand, gravel, or shell material
Barrier Island
A long, narrow island usually made of sand that forms parallel to the shoreline
Headlands
Finger -shaped projections
