What are Calderas (Volcano)?

The empty chamber of a volcano formed after the completion of the eruption is known as the Caldera. As the eruption of the volcano comes to an end, the vent and crater remain as a hollow shaped cavity. According to H.J de Blij, “A volcano‘s lava and pyroclastics come from a subterranean magma chamber, a …

Volcano and its types

A volcano is a vent in the Earth’s surface, which allows the interior molten magma to erupt out due to extreme pressure and convection. The magma when it comes out of the interior of the earth is known as lava. The lava is composed of solid and molten rocks, debris, and gases, and fluid of …

Ten causes of an Earthquake

An earthquake is an intense thrilling vibration through the earth’s surface. An earthquake may range from a minor vibration (difficult to feel) to a devastating earth movement. An earthquake is a catastrophic shake of the surface of the earth, which can cause tremendous changes over and under the surface of the earth. In the historic …

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 …
