Physical Geography

Trends in Geomorphology Geomorphology is a fundamental branch of physical geography which helps us study landforms and the processes that shape them. Over the years, several trends in the field of geomorphology have influenced the way researchers approach and understand the Earth’s landforms and landscapes. These trends include cyclic, process, quantitative, and contemporary geomorphology.

The study of landforms is a significant aspect of geomorphology. It involves examining and evaluating various features of the earth’s surface, like mountains, valleys, rivers, plains, plateaus etc, and understand how they were formed and how they have continued to evolve over time. There are several methods and approaches to study the geomorphology; Field Work: Fieldwork is the most common method to study the geomorphology of a particular area, which […]

The physical environment of our earth can be divided into four realms; 01. The solid part is known as the Lithosphere. 02. The liquid part is known as the Hydrosphere. 03. The part where living organisms are found is known as the Biosphere. 04. The air and gaseous part of the earth is known as the Atmosphere. Lets have a closer look at these realsm: Lithosphere The Lithosphere encompasses the […]

What is Groundwater? All water occuring beneath the ground surface is called “groundwater”. It has been estimated that the volume of water in the upper 0.8 kilometer of the continental crust is nearly 20 times greater than the combined volume of water in all lakes and rivers. The chief source of the groundwater is the downward percolation of the rainwater (meteoric water). Some groundwater may also be derived from juvenile […]

Work of Sea Sea Coast: The land and sea meeting place is called the “coast”. Sea coasts may have many kinds of shapes. The chief types of sea coasts are (i) steep rocky cliffs, (ii) broad low beaches, (iii) small bays alternating with rocky headlands, and (iv) sandy tidal flats. Shorelines: A “shoreline” is the line along which the water meets the land. Shorelines are classified into three groups: (i) […]

A glacier is a thick mass of ice, which moves over the ground under the influence of gravity. It originates on land from the compaction and recrystallization of snow. Glaciers form in places where more snow accumulates each year than that melts away. They are found chiefly in high attitudes as in the Arctic regions, or at high elevations as on the Himalayan mountains above the snow-line. The snow line […]

To understand the concept of the cycle of landscape evolution, let us start with a relatively flat upland area in a humid region. During the youth stage, the area remains more or less flat. The stream valleys are generally narrow. In the mature stage, the land’s relief increases, and the landscape changes into one consisting of hills and valleys. The “relief” of an area may be defined as the maximum […]

A large portion of the rainwater is absorbed by the earth’s surface. Streams are created when excess water from rain, snowmelt, or near-surface groundwater accumulates on the ground surface and begins to run downhill. This excess water from rain or snowmelt generally occurs when the water accumulates at a faster rate than the soil and organic matter can absorb the water, plants can use it, or the water can be […]

A stream in geology refers to a body of water that flows on the Earth’s surface, typically in a channel with defined banks. A water channel is known to be a stream if it has the following features; Flow: Streams have a continuous flow of water, usually moving downhill due to gravity. Size: They can range from small creeks to large rivers. Channel: Streams flow in a defined path called […]

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 […]
