The biggest types of glacier are called continental ice sheets and ice caps . They often totally cover mountains. Glaciers that flow down a valley are called valley glaciers. Outlet glaciers are valley glaciers that flow out from an ice cap or an ice sheet.
What is glacier and example?
The definition of a glacier is a huge mass of ice and snow that forms where snow gathers faster than it melts and flows along with water over an area of land . An example of a glacier is the Perito Moreno in Patagonia. ... Glaciers form over many years from packed snow in areas where snow accumulates faster than it melts.
What is glacier and types of glacier?
Glaciers are classifiable in three main groups: (1) glaciers that extend in continuous sheets, moving outward in all directions , are called ice sheets if they are the size of Antarctica or Greenland and ice caps if they are smaller; (2) glaciers confined within a path that directs the ice movement are called mountain ...
What is glacier explain?
A glacier is a huge mass of ice that moves slowly over land . The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets. Alpine glaciers form on mountainsides and move downward through valleys.
What are the two types of glacier called?
Broadly speaking, glaciers are divided into two groups: alpine glaciers and ice sheets .
What is the largest type of glacier?
The largest glaciers are continental ice sheets or icecaps , enormous masses (greater than 50,000 square kilometers [12 million acres]) of ice found only in Antarctica and Greenland. These sheets contain vast quantities of fresh water.
What are different types of glacier?
- Ice Sheets. Ice sheets are continental-scale bodies of ice. ...
- Ice Fields and Ice Caps. Ice fields and ice caps are smaller than ice sheets (less than 50,000 sq. ...
- Cirque and Alpine Glaciers. ...
- Valley and Piedmont Glaciers. ...
- Tidewater and Freshwater Glaciers. ...
- Rock Glaciers.
What is the difference between glacier and river?
River is the water bodies which is recharged by glaciers melt water, snow melt and water springs. ... A river is a body of water flowing through a definite channel from a source at a higher level to a mouth located at a lower elevation. A glacier on the other hand is a body of solid ice moving out of a snowfield.
Which of following is an example of glacier?
Answer: gangotri is an example of a glacier.
What is a melting glacier called?
Reconstituted Glacier. A glacier formed below the terminus of a hanging glacier by the accumulation, and reconstitution by pressure melting (regelation), of ice blocks that have fallen and/or avalanched from the terminus of the hanging glacier. Also called Glacier Remaniè .
What does a glacier look like?
A glacier might look like a solid block of ice , but it is actually moving very slowly. The glacier moves because pressure from the weight of the overlying ice causes it to deform and flow. Meltwater at the bottom of the glacier helps it to glide over the landscape. ... Glaciers are made up of more than just ice and snow.
What are the layers of a glacier?
The dark and light layers comprise coarse-clear ice (summer ice – pore spaces infilled with refrozen meltwater) and white bubble-rich ice (winter snow). Primary stratification may be visible in the field or on high-resolution remotely sensed images in the ablation parts of a glacier.

What are the 2 main types of glaciers and give examples of their locations?
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.
