The ice core can be used to know how the ice spreading during glacial and interglacial period. The ice core can tell us about past climatic information and also the possible track of future climatic change.

  • Ice is considered to be the best preserver of fossils . Many great mammals like mammoth, dinosaurs etc were identified and analysed from the remains which were found in antarctic region.

  • The ice also has bubbles of trapped gas that reveals the old volcanic eruptions and gives us an idea about the earth's early atmosphere.

  • Scientist spend many years exploring the ice caps of poles and other area and have succeeded in gathering a huge information about the above points.

AveGali [126]

Landslides along cut banks are common; a landslide along a cut bank affects the discharge of a river because the landslide the discharge would increase because the cross-sectional area of the river would increase.

Landslides are resulting from disturbances in the herbal stability of a slope. They are able to accompany heavy rains or comply with droughts, earthquakes, or volcanic eruptions. Mudslides broaden while water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.

The cross-sectional area is the place of a -dimensional form that is obtained while a three-dimensional item - which includes a cylinder - is sliced perpendicular to some special axis at a factor.

Cut banks are caused by the moving water of the river sporting away the earth. A factor bar then again is placed on the interior of a bend in a river (meander). Because the river curves around the bend within the river, the water slows down and sediment is dropped to the river bed.
