How is Glacial ice different?

It is formed by layered and compressed unmelted snow

What is zone of ablation?

Where glacial loss takes place, mostly to melting.

What is the zone of accumulation?

Where snowfall occurs throughout the summer and the glacier gains mass

When I gamble. Just kidding, you don't get hints

What is the equilibrium line?

Between the zone of accumulation and the zone of ablation where gains equal loss

Ice cap

Glacial coverings so tall only the mountain tops show

Ice field

Glaciers converging into valleys

Similar to river to tributary

Firn

Granular compacted snow

True or false, glaciers move by accumulation of material at the base

False


The whole glacier flows

What is a surge?

Rapid glacial movement

Crevasses

Large vertical cracks within the rigid, brittle upper layer of a glacier

What parts of a glacier move slowest?

sides

Cirque

A bowl shaped steep sided depression in bedrock with a sloping floor

How do cirque basins form glaciers?

They fill with ice and spill. The resulting spill becomes a glacier

Valley glacier

Glacial ice filling a valley (not necessarily all the way)

Lateral moraine

Sediment moved and accumulated by a glacier on its sides

Medial moraine

When two glaciers converge their lateral moraines form a medial moraine

Think Median

End moraine

A place where a glacier stopped and sediment accumulated infront of it.

Plucking

When blocks or fragment of bedrock are broken loose and carried with the glacier

Tributary glacier

Converging glacier that contributes to the flow and mass of another glacier

Basal Ice

The bottom ice layer of a glacier

Basal slip

Glacial sliding caused by the lubrication from the meltwater beneath it

Ice regelation

Ice melting due to friction. Rough surfaces increase the rate of this process

What are the pros of glacial erosion compared to liquid water?

Large


Heavy

What are the cons of glacial erosion compared to liquid water?

Slow


No chemical weathering


No dissolving


No game, son

Abrasion

Rock on rock crime (erosion)

Grooves are created from?

Large rocks the glacier dragged along

Striations are made from?

Coarse sand, pebbles

Polish is caused by?

silt being dragged by a glacier

Drift

Any type of glacial deposit

Where are the 4 places glacial transport can take place?

Within the glacier


Above the glacier


On the glacial bed


Within meltwater

Stratified drift

Shit is from meltwater

Outwash

Stratified drift that is well sorted

Ice contact

Stratified drift that is poorly sorted

Dirty ice

When a glacier plows through a end moraine and picks up the sediment

What kind of glacier erodes rock and sharpens it?

Valley

What two landforms are created from eroding and sharpening a mountain

Horn: sharpened peak


Arete: sharpened ridges

What three affects does a post glacier valley have

U shaped Valley


Hanging waterfalls


Fjord

Fjord

Narrow, steep sided, elongated inlet (bay like area) formed when a glacier leaves and seawater takes its place

Tarn

A lake dammed by a moraine

Till Plain

Unsorted deposits characterized by a low, rolling relief

What's the difference between a till and a moraine

Moraine: ridge


Till: Flatish

Stratified drift

Distinct layers of deposited sediment

Proglacier lake

A lake infront of a glacier formed from meltwater

Outwash plain

Plain formed by a receding glacier. Has both removed material and deposited material

Drop stone

When a glacier drops a rock in a body of water

Fine grain is an indicator of what kind of water flow?

Lesser

Large rocks are an indicator of what kind of water flow?

greater

Kettle lake

A chunk of glacial ice


Covered by sediment


Melts creating a depression


And fills up with water

Esker

Snake like ridges created from the sediment from rivers inside glaciers

Kames

A mound created from a river running off a continental glacier and depositing sediment

Terminal moraine

The furthest end moraine

Drumlin

A long smear of high topographic area that got ****** up by a ****** glacier

Great lakes in North America were formed as

Glacier carved deep troughs that filled with meltwater
