What formation caused Calderas?

Volcanic, collapse of where magma has been ejected.

What formation causes Pyroclastic lakes?

What formation causes Lava Dam Lakes?

Volcanic, formed by emission of lava rerouting water

What formation causes Moraine lakes?

Glacier, mountain valley dammed by the gravel left at end of glacial advance

What formation causes Tarn/Cirques?

Glacier, at the base of a glacier or where a glacier was, typically above moraines.

What formation causes paternoster lakes?

Glacier, a chain of cirques connected by a stream.

What formation causes Kettle Lakes?

Glacier, formed by chunks of ice left behind after glaciers.

What formation causes Scour lakes?

Glacial, glacial scour lakes are caused by complext glacial and tectonic processes.

What formation causes cryogenic lakes?

Glacial, freezing and thawing in areas of permafrost

What formation causes sinkhole lakes?

Lakes formed like sinkholes are solution dissolution basins, where a sinkhole forms over a cave full of water.

What causes landslide lakes?

When a landslide dams a valley and debris dams water into a lake.What

What formation causes oxbow and floodplain lakes?

Fluvial lakes, where a river forms lakes via sediment deposition.

What formation causes Aeolian lakes?

Lakes formed by wind

What causes meteoric lakes?

meteors.

What causes animal origin lakes?

Animals such as beavers, often cost alot of money because how substantially they can effect their enviornment.

What causes human made lakes?

Reservoirs and bomb craters, many other kinds

What are characteristics of grabens? Whats an example?

Long, narrow, and deep. Lake Baikal in Russia

What are characteristics of uplift lakes? What is an example?

Typically shallow and round. Lake Drummond, VA (Dismal Swamp)

What are characteristics of calderas? Whats an example?

Often round and deep, Crater Lake, OR, very round, deep, and clear.

What are characteristics of Moraine Lakes? What is an example?

Often long and skinny and deep, facing which way the glacier receeded, North to south for finger lakes

What are characteristics of Tarns?

A type of moraine impoundment small and high in the mointains above a moraine.

What are characteristics of Kettle lakes?

Prarie potholes, small shallow lakes in flatlands.

What are characteristics of Cryogenic lakes?

Typically small and shallow, ovel and oriented by summer wind.

What are characteristics of Solution/Dissolution lakes?

Foremd by dissolution of bedrock in area of carbonate and a sinkhole connecting to undeground water.

What are characteristics of Landslide lakes? What is an example

Often temporary, debris like trees rock and sediment damming water body. Mountain Lake, VA

What are characteristics of Fluvial lakes?

Nearby a river, broken off via sediment deposition, oxbow lakes are oxbow shaped.What

What are characteristics of Aeolian Lakes?

Formed by wind, usually small temporary lakes in dunes.

What are characteristics of reservoirs lakes? What is an example?

from major infrastructural projects to farm ponds. Typically dendritic upstream waterbodies. Smith Mountain Lake, VA.

What are ecological impacts of dams?

Collect alot of sediment, negatively affect fish migration and stream connectivity, change water temps, many more.

What lakes are formed from volcanic explosions causing a hole that is filled with water?

Calderas, a form of Volcanic lakes.

What type of lake is formed when limestone dissolves and a lake forms where the hole is?

Dissolution Lake

What kind of lake is formed when a river bend pinches off?

Oxbow.

What do tectonic lakes look like?

Can be very old and very deep

What do Kettle lakes look like?

Small lakes/wetlands formed from ice retreating

What do moraine lakes look like?

Narrow with a dam of rock and debris from the glacial activity

What do earthslide lakes look like?

Similar to reservoirs but formed by natural events, often dammed with a variety of sediments.

What do volcanic calderas look like?

Round and deep

What do dissolution lakes look like?

Small lakes with steep edges, often like a pothole. Often very clear.
