what are two basic types of glaciers where is each type found?

There are two primary types of glaciers: Continental: Ice sheets are dome-shaped glaciers that flow away from a central region and are largely unaffected by underlying topography (e.g., Greenland and Antarctic ice sheets); Alpine or valley: glaciers in mountains that flow down valleys.

Continental glaciers, also called ice sheets, cover large amounts of land in the Earth's polar regions. The largest ice sheets are located in Antarctica. In the Arctic region, an ice sheet covers Greenland and there is an ice sheet in Iceland. ... Alpine glaciers are found in high mountain valleys worldwide.

An ice sheet is a chunk of glacier ice that covers the land surrounding it and is greater than 50,000 kilometers (20,000 miles) wide. An ice sheet is also known as a continental glacier. ... Ice sheets are usually warmer at their base than on the surface. That is because of geothermal heat.

Three conditions are necessary to form a glacier: (1) Cold local climate (polar latitudes or high elevation). (2) snow must be abundant; more snow must fall than melts, and (3) snow must not be removed by avalanches or wind.

There are three main types of mountains: fold mountains, fault-block mountains, and volcanic mountains. They get their names from how they were formed. Fold mountains - Fold mountains are formed when two plates run into each other or collide.

Explanation: In short, large masses of ice (glaciers) at high altitude tend to migrate down mountains. ... Then because of the glaciers weight the material below it begins to be removed. As the material is removed a big pit begins to form and voilà, a cirque!

The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Sea ice grows, forms, and melts strictly in the ocean. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean.

Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.

Types of glacial landform There are diagnostic landforms associated with wet-based sheet flow, ice streams, and surging ice. Surging glaciers are a particular phenomenon where the ice flows periodically fast and then more slowly, and are uncommon in Antarctica.

Continental glaciers are large ice sheets that cover relatively flat ground. These glaciers flow outward from where the greatest amounts of snow and ice accumulate. Alpine (valley) glaciers flow downhill. Ice accumulates near the top of a mountain and then travels down existing valleys (Figure below).

During movement there are three parts of the glacier: The zone of basal sliding; the zone of plastic flow; and the rigid zone. The rigid zone is brittle and sometimes is broken into crevasses. Ice sheets move with these three zones but often spread laterally rather than flow downslope.

Glacial cirques are found amongst mountain ranges throughout the world; 'classic' cirques are typically about one kilometer long and one kilometer wide. Situated high on a mountainside near the firn line, they are typically partially surrounded on three sides by steep cliffs.

Answer and Explanation: Temperature has a big impact on glaciers, with warmer annual temperatures equaling smaller glaciers.
