Stonehenge rocks wales Stonehenge is actually located in Wiltshire, England, not Wales. These rocks are associated with Wales because they are taken from Wales. It is a prehistoric monument consisting of a ring of standing stones, each around 13 feet high, seven feet wide, and weighing around 25 tons. The purpose and construction of Stonehenge have been subjects of much debate among scholars and archaeologists. Stonhenge rocks wales While Stonehenge […]

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 “erosional landforms”, while the landforms coming into existence as a result of deposition of material are known as “depositional landforms”. See “erosional landformds”. Depositional Landforms The evident landforms resulted from the deposition of sediments or rocks after they had been […]

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 features of stream erosion are varied and can be observed in different forms. Here are some key features associated with stream erosion: Features of Stream Erosion (water Erosion) V-Shaped Valleys Erosion by flowing water often results in the formation of […]

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 synonymously, the term “river” is preferably used to denote a mainstream into which several tributaries flow. Read: Features of Stream Erosion The geological work of the stream is to “erode” the valleys, “transport” the material that is eroded, and “deposit” […]

Great Sand Dunes National Park and Reserves is located in South Colorado, USA. The nearest city to the park is Alamosa, which is at a distance of about 30 miles. The park is famous for its charming dunes in the shape of towering stars. It is famous for its huge sand dunes, and for the seasonal Medano Creek and beach created at the base of the dunes. The backcountry Medano […]

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 slope surfaces, water channel banks, or other erosion-prone land surfaces. Natural and synthetic fibers are used to make these blankets. These mates are designed to provide temporary protection to the soil until vegetation can grow and take over the responsibility […]

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 in the wind accumulates wherever it meets any obstruction, such as a boulder or a bush. As the accumulation of sand grows, it traps even more sand. In this manner, dunes are created. Sand dunes have a gentle slope (5° […]

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 wind erosion is not restricted to arid and semiarid regions, it does its most effective work in these areas. Wind does erosion in three ways: (i) deflation, (ii) abrasion, (iii) attrition. (1). Deflation: Lifting and removal of loose material by […]

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 means “Earth Writing”, or Writing about the Earth. The word Geographia was first used by a Greek Philosopher “Eratosthene”, who lived from 274 BC to 194 BC. Geography is a systematic study of the Earth. Before the introduction of the […]

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 action of various erosional agents. These agents include water, wind, ice (glaciers), or gravity. It plays a significant role in shaping and featuring the Earth’s surface over long periods of time. Erosion can occur in different environments and landscapes, including […]
