How do glaciers transport the earthen material?

Glaciers move very slowly from uplands to the lowlands. The transport of glaciers has a deep impact on the landscape. The moving glaciers drift the rocks and the debris along with them. This transportation of the debris is known as glacial transportation. The whole glacier work is carried out in the following forms.  Weathering caused …

Transport by Glaciers

Glaciers are the moving ice bodies toward the downslope. The moving bulges of the ice also cause transportation of other material present on the earth’s surface. The process of moving rocks and debris along with the glacier’s movement is known as the Transportation caused by glaciers. Glaciers squire a huge amount of rock debris by …

Classification of Glaciers on the basis of thermal stat

Other Classifications By Thermal State Temperate Glacier: A glacier, whose ice remains near the melting point all through the year. The temperature of the ice is equal from the base layer to the top layers. Their temperature remains between zero degrees celsius to 4 degree celsius. Glaciers of North America, South America, Europe, Asia, Africa, …

Folds and Foldings

Folds and Folding:  The bend or the wrap of layered rocks is known as a fold. When a crystal rock comes under pressure and stress, it tends into Basins a hundred kilometers across along with normal faulting action. The size of the folds may differ based on the difference in the landscape. Some are too …

Work of Glaciers

WORK OF GLACIER: A thick moving mass of ice under the influence of gravity on earth is called a Glacier. The snowfall becomes a glacier after being dumped and compacted. The frequent snowfall in a region causes glaciations. The underlying layer of snow is compressed by the newly fallen snow. The compressed layer of the …

Faults and Faulting

FAULTS AND FAULTING: A faults is a fracture in the crystal rock involving the displacement of rock on one side of the fracture with respect to the rock on the other side. On the other Hand, a fracture without displacements is called a joint. According to Arthur N.Strahler, “ A fault is a break in …

Plate tectonics; All you need to know about plate tectonics

PLATES-TECTONICS: The word tectonic means deformation within the Earth’s crust and the geological structures produced by deformation, including folds, faults and development of mountain chains. Plate Tectonics: Plate tectonics is the theory or model to explain the distribution, evolution, and causes of the Earth’s crystal features. It proposes that the crust and part of the …

Economic importance of the rocks

Economic Importance of the Rocks: Rocks are classified into three types. This classification is based on their origin, formation, properties, and composition. The very first type of rock is an igneous rock. Igneous rock is the one, which is extruded from the internal molten mantle in the form of Lava. The molten lava, when exposed …
