Front 1

Erosion

Back 1

The process by which Natural Forces move weathered rock and soil from one place to another

Occurs where the agents of erosion deposit or lay down sediment

Front 4

Gravity

Back 4

The force that moves Rock and other materials downhill

Front 5

Mass movement

Back 5

Gravity causes mass movement, which is any of the several processes that moves sediment downhill

Front 6

What are the four different types of mass movements

Back 6

Landslides mudflows slump and creep

Front 7

Landslides

Back 7

The most destructive kind of mass movement and occurs when rock and soil slide quickly down a steep slope

Front 8

Medflow

Back 8

The rapid downhill movement of a mixture of water Rock and soil

Front 9

Slump

Back 9

When a mass of rock and soil suddenly slipped on a slope all together in one big chunk

Front 10

Creep

Back 10

The very slow downhill movement of rock and soil

Front 11

What is the major agent of erosion

Back 11

Moving water

Front 12

Runoff

Back 12

Water that moves over Earth's surface

Front 13

Rills

Back 13

Tiny grooves in the soil

Front 14

Gully

Back 14

A large groove or channel in the soil that carries runoff after a rainstorm

Front 15

Stream

Back 15

A channel along which water is continually flowing down a slope

Front 16

Tributary

Back 16

A stream or river that flows into a larger River

Front 17

Stream

Back 17

A channel along which water can he sleep flying down a slope

Front 18

What are some river formed features

Back 18

Valleys waterfalls floodplains Meander's oxbow lakes

Front 19

Waterfalls

Back 19

Occur where a river meets an area of rock that is very hard and a Road Slowly

Front 20

Floodplain

Back 20

The flat wide area of land along a river

Front 21

Meander

Back 21

A loop like Bend in the course of a river

Front 22

Oxbow lakes

Back 22

A meander that has been cut off from the river

Front 23

What are three different types of deposits by Rivers

Back 23

Olivia fans deltas and soil on floodplains

Front 24

Alluvial fans

Back 24

A wide sloping deposit of sediment formed where a stream leaves a mountain range

Front 25

Delta

Back 25

Where sediment flows from a river into an ocean or lake and builds up and landforms

Front 26

Floodplain

Back 26

When Heavy Rain or melting snow cause the river to rise above it spread out over it's floodplain

Front 27

Groundwater erosion

Back 27

Is the process of chemical weathering

Front 28

Groundwater

Back 28

The term geologists use for the underground water

Front 29

Stalactite

Back 29

A deposit that hangs like an icicle from the roof of the cave

Front 30

Stalagmite

Back 30

Slow dripping builds up cone-shaped stalagmite from the

Front 31

Karat topography

Back 31

A rainy region where there is a layer of limestone near the surface groundwater erosion can significantly change the shape of the land

Front 32

energy

Back 32

The ability to do work or cause change

Front 33

potential energy

Back 33

The energy that is stored and we need to use later

Front 34

potential energy

Back 34

The energy that is stored and we need to use later

Front 35

Kinetic energy

Back 35

The energy an object has due to its motion

Front 36

Abrasion

Back 36

The weathering away of rock by a grinding action

Front 37

Load

Back 37

The amount of sediment that a river carries

Front 38

What affects how fast a river flows in how much sediment can a road

Back 38

Rivers slope volume of flow in the shape of its steam bed

Front 39

Slope

Back 39

Generally Rivers slope increases the water speed also increases

Front 40

Volume of flow

Back 40

A reverse flow is the volume of water that move past that point on the river at a given time

Front 41

Steam bed sheet

Back 41

A steam bad shape affect the amount of friction between the water and the steam bed

Front 42

Friction

Back 42

The force that opposes the motion of one surface as it moves across another surface

Front 43

Turbulence

Back 43

When instead of moving Downstream the water moves Every Witch Way in a type of movement

Front 44

Continental glacier

Back 44

A glacier that covers much of a continent or large island

Front 45

Ice Age

Back 45

When in the past continental glaciers have covered large parts of Earth's surface

Front 46

Valley glaciers

Back 46

A long narrow Glacier that forms when snow and ice build-up high on the mountain valley

Front 47

Plucking

Back 47

As a glacier flows over land it picks up rocks

Front 48

Till

Back 48

The mixture of sediment that a glacier deposits directly on the surface

Front 49
