All about the Earth's natural environment, features, and processes, focusing on landforms, climate, soils, water, and ecosystems.
Introduction to Erosion Erosion is a natural geological process that involves the removal and transportation of disintegrated soil and rock particles, or sediment from one location to another by the…
The word Geography has been derived from the Greek word “Geographia”, which consists of two words “Geo” and Graphia”. Geo means the Earth, and Graphia means to write. Collectively Geographia…
The air current in motion is called “wind”. The wind is an important agent of erosion, transport and deposition. Its work is particularly seen in arid regions. Wind Erosion Although…
Sand Dunes The strong action of wind generally deposits sand in the form of mounds. These sand mounds are known as “Sand Dunes”. The sand traveling as a bed load…
What is an Erosion Control Blanket (ECB)? An erosion control blanket (ECB), also known as the erosion control mat or fabric, is a material made to prevent soil erosion on…
The term stream includes the channelized flow of any size, from the smallest brook to a very large river like the Amazon. Although the terms “river” and “steam” are used…
Stream Erosion/Water Erosion refers to the process by which flowing water (rivers or streams) wears away the Earth’s surface, thus transporting away the sediments and shaping the landscape. Some prominent…
There are two types of landforms; (i) erosional landforms, and (ii) depositional landforms. Landforms resulting from erosional activities of different erosional agents, like water, glaciers, and wind are known as…
Longitudinal Profile The plot of the relative elevation of a stream bed from headwaters to mouth is called its “longitudinal profile”. In other words, the longitudinal profiles are plots of…
A natural drainage system refers to the network of flowing water. We can find flowing water in the form of rivers, streams, lakes, wetlands, and groundwater. This network of natural…
