By the geological procedure, erosion happens. All the natural forces contribute to this happening. All the earthen materials shift itself from one place to another, and the forces like water and wind assist in it. Exogenous developments remove rocks and soil from the outer layer of the soil and then transfer it to another location…
Erosion is the process of constant disintegration of rocks and surfaces due to physical factors like wind, ice, water, and climate change. Thus it is just the opposite of deposition, a process by which particles get deposited at a place by some physical factors. Erosion is also the opposite process of siltation. Weathering, on the…
The river is a natural stream of flowing water with a significant volume of freshwater. Rivers are found everywhere, on every land, and every continent. They start from source or headwater areas such as springs, glaciers, and flow in meandering paths at different speeds. Finally, they discharge into a larger river, or lakes, or most…
Mechanical weathering is the process through which large rocks are broken into increasingly smaller pieces. Sometimes referred to as physical weathering, the process normally happens near the Earth’s surface. Can you believe that the tiny sand grains you see at the beach were once part of massive rocks? It involves mechanical processes that disintegrate a rock,…
Phosphorous is a crucial nutrient for plants and animals. For instance, it forms an integral component of genes and also plays a significant role in the Adenosine Triphosphate (ATP) energy cycle. Without phosphorous, you wouldn’t be able to contract your muscles. The phosphorus cycle refers to the biogeochemical cycle by which phosphorous moves through the…
When you stand at a vantage point of space, you’ll be treated to an array of breathtaking landforms. However, these beautiful pieces of nature can only qualify as landforms if nature created them. This means human-made dams, vehicles, and buildings cannot be called landforms. Mountains, hills, plains, plateaus, beaches, sea stacks and canyons all qualify…
If you look out of your window, you’ll probably see buildings, trees, telephone poles and so on. The world we live in today has mostly been shaped by humans. However, it’s not only humans that are moving things and shaping the planet. Rain, wind, and other natural elements shape the earth all the time, leaving…
Landslides are among the many natural disasters causing massive destructions and loss of lives across the globe. According to a survey study by the International Landslide Centre at Durham University, UK, 2,620 fatal landslides occurred between 2004 and 2010. These landslides resulted in the death of over 32,322 people. The figure does not include landslides…
Mass wasting can be defined as a geomorphic process. A geomorphic process is a natural course of weathering, erosion and deposition that causes alteration of the surface materials and landforms of the earth. Mass wasting is also known as slope movement or mass movement. It can be described as the potency by which certain landforms like…
Rocks, minerals, soils normally change their structure under the action or influence of certain environmental forces. Biological activity, extreme weather, and agents of erosion such as water, wind and ice are examples of environmental forces that influences the continuous breakdown, wearing away and loosening of rocks and soils. This is what is termed as weathering….
Sedimentary rocks are the most common rock types which are freely exposed on the earth’s surface. They are formed from other rock materials since they are made up of the buildup of weathered and eroded pre-existing rocks. The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological…
