A glacier is a thick mass of ice, which moves over the ground under the influence of gravity. It originates on land from compaction and recrystallization of snow. Glaciers form in places in places where more snow accumulates each year than that melts away. They are found chiefly in high latitudes as in Arctic regions or in high altitudes as on high mountains like Andes, Rockies, Eurapean Alps, Alaska’s Brooke […]

The present status of geomorphology is the result of the gradual, but successive evolution of geomorphological thoughts postulated in different periods by innumerable philosophers, experts and geoscientists in the subject and outside the subject. Thus, the developmental phases of geomorphology indicate its dynamic nature. After taking its birth in the philosophical ideas of the ancient Romans and Greeks the subject has blossomed through the geomorphological methodological nutrients of the 18th […]

What is Geomorphology? Geomorphology is a branch of Geography, which is similar to the subject of Geology. It deals with the study, origins, development and classification of the landforms. It also discusses the processes impacting on the landforms. These processes shape the Earth’s surface, such as weathering, erosion, tectonic activities and volcanism. Geomorphologists investigate the topography of the Earth and seek to understand the forces and factors that contribute to […]

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 features manages the flow of water across the landscape. These systems are essential for transporting water from higher elevations to lower elevations, regulating the water cycle, replenishing groundwater supplies, supporting ecosystems, and preventing flooding. Here’s a breakdown of the components […]

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 the elevation vs distance from the stream mouth to the upper reaches within the watershed basin. The longitudinal profile of a stream is generally concave upward, which is in accordance with the steady downstream decrease in slope. They help to […]

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 […]
