Short Notes:
1. Inselberg.
Ans: An inselberg is an isolated hill or mountain that stands above the surrounding landscape. It is formed through erosion and weathering of the surrounding rocks.
Geologically speaking, an inselberg is a hill of hard volcanic rock that has resisted wind and weather and remained strong and tall as the land around it eroded away.
2. Oasis.
Ans: An oasis is a fertile spot in a desert where water and plants are found. It is formed when underground water rises to the surface, creating a haven for vegetation and wildlife.Oasis are irrigated by natural springs or other underground water sources. They vary in size from a cluster of date palms around a well or a spring to a city and its irrigated cropland.
3. Sand Dunes.
Ans: Sand dunes are hills of sand formed by wind action in deserts. They can be longitudinal or transverse, depending on the direction of the wind.Dunes form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate. Every dune has a windward side and a slip face.
4. Glaciers.
Ans: A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity. Glaciers are slow-moving rivers of ice formed by snow accumulation in high-latitude or high-altitude regions. They can be continental, mountain, or piedmont glaciers.
5. Moraines.
Ans: Moraines are ridges of debris formed by glaciers. A moraine is material left behind by a moving glacier. This material is usually soil and rock. Just as rivers carry along all sorts of debris and silt that eventually builds up to form deltas, glaciers transport all sorts of dirt and boulders that build up to form moraines.They can be ground moraines, lateral moraines, or terminal moraines, depending on their location and formation.

5. What is the term for a glacier that forms in a valley?
Ans: Valley glacier.
6. What is the term for a glacier that forms at the foot of a mountain?
Ans: Piedmont glacier.
7. What is the term for the bottom of a glacier valley?
Ans: Glacial trough.
8. What is the term for the side of a glacier valley?
Ans: Glacial slope.
9. What is the term for the debris carried by a glacier?
Ans: Moraine.
10. What is the term for the process of glacier movement?
Ans: Glacial flow.
11. What is the term for the study of glaciers?
Ans: Glaciology.
12. What is the term for the formation of glaciers?
Ans: Glaciation.
13. What is the term for the melting of glaciers?
Ans: Deglaciation.
14. What is the term for the movement of glaciers?
Ans: Glacial movement.
15. What is the term for the erosion caused by glaciers?
Ans: Glacial erosion.
16. What is the term for the deposition caused by glaciers?
Ans: Glacial deposition.
17. What is the term for the rocks carried by glaciers?
Ans: Glacial erratics.
18. What is the term for the scratches on rocks caused by glaciers?
Ans: Glacial striations.
19. What is the term for the polish on rocks caused by glaciers?
Ans: Glacial polish.
20. What is the term for the formation of glacial lakes?
Ans: Glacial lake formation.
21. Describe the formation and movement of glaciers.
Ans: Glaciers are formed through the accumulation of snow in high-latitude or high-altitude regions. The movement of glaciers is slow and can be influenced by factors such as temperature, precipitation, and topography. Valley glaciers flow down valleys, and continental ice sheets flow outward in all directions. Glaciers move by internal deformation of the ice, and by sliding over the rocks and sediments at the base.Glaciers can be classified into different types based on their location and formation, including continental, mountain, and piedmont glaciers.
22. Discuss the effects of global warming on glaciers.
Ans: Global warming is having a significant impact on glaciers around the world. Rising temperatures are causing glaciers to melt at an unprecedented rate, leading to sea-level rise, changes in ocean currents, and impacts on local ecosystems. Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land. The effects of global warming on glaciers are far-reaching and have significant implications for the environment and human societies.
