DEPOSITIONWHEN EROSION DROPS SEDIMENTS AS THEY LOSE ENERGY.

This impacts life by moving things to other places that it needs to be.Example: Waves washing shells on shore.

Page 3: Sediments

Erosion Is a process that wears away surface materials and moves them from one place to another.

Let’s Dumb It Down!Things are broken down and

moved from their original place.

Ever see little pebbles on your way home laying on the sideway? Those little pebbles used to be apart of one big rock. By the power of Erosion, the rock lost some of its covering, producing the pebbles.

• Definition: Type of erosion that happens as gravity moves materials downslope.

• Examples: Creeps, Rockfalls, Rock Slides, and Mud Flows

• Impacts Life: Where you want to live and crop food.

Slump• A large material slips down along a

curved surface.• Slump affects life by putting a hole

in the ground & it leaves a curved scar in the ground.

Page 6: Sediments

CreepCreep is when the slope of the surface cause the material to slowly slide & bend .

This impacts life because it takes our structures & surroundings & moves them down hill or tilts them.

Page 7: Sediments

Rock falls and Rock Slides

Rock falls happens when blocks break loose from a steep slope, and tumble through the air.

Rocks slides happens when usually steep layers of rock slips down slope.

Page 8: Sediments

MudFlow

A thick mixture of sediments and water flowing down a slope.

A glacier is a large mass of ice and snow moving on

land under its own weight.

GLACIERThis is the Milk Lake Glacier.

Continental and Valley Glaciers Continental Glaciers

are thick, they’re located mostly near the “Poles”, they make it impossible to see most of the land features in Antarctica and Greenland.

Valley Glaciers occur in warmer climates. In high mountains when the average temperature is low enough where they don’t melt in the summer, Valley Glaciers grow and creep along.

Page 11: Sediments

PluckingProcess that adds gravel, sand, and boulders to a glacier’s sides as water freezes and thaws, breaking off pieces of surrounding rocks.

In result of plucking glacier’s cause less damage to their surroundings.

Striations Shallow grooves on rocks

caused by glacier

=

It shows where

a glacier has

been and takes

lots of sediment

with them that

ruins the land.

Page 13: Sediments

Till A till is a mixture of different sized

sediments left behind by glaciers. An example of a till is Tills impact life because they can cover huge areas of land.

What is an moraine?A moraine is a glacially formed accumulation of glacial debris which can occur in currently

glaciated, such as those acted upon by a past glacial maximum.

A moraine effects the life of people because they waste millions of

dollars to support the moraine and to keep it under control.

OutwashWhat is an outwash ?

Outwash is sediment deposited by streams flowing away from melted glaciers

How does outwash affect life?

Outwash affects landscape by glaciers.

Eskers

When the glacier melts a winding ridge of sand and gravel is left

behined.

Esker impact people lives because when it ice up there is a tunnel underneath the ice. When it melt the water makes a small stream .

DEFLATIONDefinition A process of erosion that occurs when winds blows sediment of soil away and leaving a coarse sediment behind.Wind Soil After Deflation

How Does It Impact Life?

This impacts life because it changes the texture of the soil,

causing the soil to become un-

farmable.By: Caitlyn Segear

Page 18: Sediments

Abrasion

Abrasion occurs when the surface of a of a rock gets scraped and worn away, by a windblown

sediment that strikes the rock.

Page 19: Sediments

Dust stormsDefinition-dust storms are when the soil is dried out and can be blown high in the air by the wind.

This impacts life because it can kill people and ruin peoples cars. It can also ruinPeoples freedom from going outside. People are going to have to worry about Surprise dust storms.

Page 20: Sediments

LOESS Fine grain sediment blown and

deposited by the wind.

This impacts life because it can cause some soil to be more fertile and can also cause hill like structures such as the one to the left.

Dune- A mound of sediments drifted by the wind.

How it impacts life- Without dunes there would be no barrier around places near the shore.
