Earth Science Chapter 12 Review

slender mountain peak erode by glaciers

most sediment load

deposit of sediment left by a glacier

strip of till that extends from where 2 glacial valleys meet

soil scientist

importance of biological soil crusts

mass of weathered rock debris at the  bottom of a cliff

thin bands of sediment formed on the bottom of lakes fed by glacial meltwater

amount of sediment carried by the stream

formed by deposition

method of erosion control involving planting in horizontal rows that follow the hill's shapes

large mass of ice that moves under the influence of gravity

layer of debris carried from the terminus that is sorted and deposited by meltwater

forming a delta

long, streamlined hills of unsorted glacial till

erosion by sand carried by wind

forms clay

raising of rocks and boulders caused by ice below the earth's surface

winding ridge of sorted sediment deposited by a glacier

sudden glacier movement

agent always involved in weathering

rapid movement of a large mass of earth down a slope

glaciated valley that is full of ocean water

mechanical weathering

typical order of the processes

most favorable condition for weathering

water enters a crack in a rock, freezes and causes the rock to crack

a type of mass wasting that slips a short distance

layer of soil caused by the weathering of bedrock

narrow ridge between 2 glaciated valleys

slow movement of land surface

combination of rocks, pebbles, sand and silt carried by glaciers

topsoil with equal parts sand & silt and 1/2 as much clay

cause of loess

cause of plucking

a stream

hill or ridge of windblown sand

depression in a ground moraine from when a block of ice melted

water + carbon dioxide

shape of a glaciated valley

soil in rainy climates

bowl-shaped depression caused by strong winds

erosion by wind itself

the result of 2 glaciers merging and spreading onto a plain at the mountain base

a steep hollow excavation made by glacial erosion in a mountain

all fertile soils contain
