1 SedimentsSediments are loose materials (that include rock fragments and mineral grains) that have been moved by erosional forces.By: Michael Saler
2 Deposition When 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.Deposition When erosion drops sediments as they lose energy.Mya Odrick6th Period
3 Erosion Let’s Dumb It Down! 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.
4 By: Moraima RiveraMass MovementDefinition: Type of erosion that happens as gravity moves materials downslope.Examples: Creeps, Rockfalls, Rock Slides, and Mud FlowsImpacts Life: Where you want to live and crop food.
5 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.
6 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.
7 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.
8 A thick mixture of sediments and water flowing down a slope. MudFlowA thick mixture of sediments and water flowing down a slope.
9 GlacierA glacier is a large mass of ice and snow moving on land under its own weight.This is the Milk Lake Glacier.Carlee.Period 6
10 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.
11 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.
12 Shallow grooves on rocks caused by glacier =StriationsShallow grooves on rocks caused by glacierIt shows where a glacier has been and takes lots of sediment with them that ruins the land.
13 TillA till is a mixture of different sized sediments left behind by glaciers.An example of a till isTills impact life because theycan cover huge areas of land.
14 Moraine Jake 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.
15 Outwash By: Ashley Randle What is an outwash ? Outwash is sediment deposited by streams flowing away from melted glaciersHow does outwash affect life?Outwash affects landscape by glaciers.By: Ashley Randle
16 Nate H.NEskersWhen 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 .
17 DeflationDefinitionA process of erosion that occurs when winds blows sediment of soil away and leaving a coarse sediment behind.WindSoil After DeflationHow 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
18 AbrasionAbrasion occurs when the surface of a of a rock gets scraped and worn away, by a windblown sediment that strikes the rock.
19 Dust storms Definition-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 aboutSurprise dust storms.
20 Fine grain sediment blown and deposited by the wind. LoessFine 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.
21 Dune- A mound of sediments drifted by the wind. TymbyrDune- A mound of sediments drifted by the wind.How it impacts life- Without dunes there would be no barrier around places near the shore.
