What is Exogenic process? Exogenic : Processes occuring on the Earth’s surface and that generally reduce relief. These processes include weathering and the erosion, transport, and deposition of soil and rocks; the primary geomorphic agents driving exogenic processes are water, ice, and wind.
What is geomorphology PDF?
Geomorphology is the study of landforms and landform evolution. The topic traditionally has been studied both qualitatively, which is the description of landforms, and quantitatively, which is process-based and describes forces acting on Earth’s surface to produce landforms and landform change.
What are the 3 types of exogenic processes?
Exogenic Processes or Denudation
Weathering, mass wasting, erosion, and deposition are the main exogenic processes.
What are 2 types of weathering?
Weathering is often divided into the processes of mechanical weathering and chemical weathering. Biological weathering, in which living or once-living organisms contribute to weathering, can be a part of both processes.
What is the importance of Exogenic process?
Exogenic processes (e.g., mass movement, erosion, and frost weathering) play an important role in the formation of relief and create a variety of landscapes.
What are the types of geomorphology?
There are many sub disciplines in geomorphology including tectonic, fluvial, storm, aeolian, floodplain, glacial, groundwater, climate, tsunami, and many others. These sub disciplines are mainly driven by distinctions in the mechanics and dynamics involved in the processes.
What are the two types of base levels?
There are two types of base level- ultimate base level and local base level. The ultimate base level is sea level where the majority of water stream loses their mightiness. The local base level at which the river can erode its bed locally.
Who is father of geomorphology?
William Morris Davis (February 12, 1850 – February 5, 1934) was an American geographer, geologist, geomorphologist, and meteorologist, often called the « father of American geography ».

What are the main endogenic processes?
The Main Endogenic Processes are Folding and Faulting (or tectonic movements). The Subsequent Endogenic Processes are Volcanism, Metamorphism, and Earthquakes. Endogenic processes cause many major landform features.
What are the 5 geomorphic processes?

What are the four main types of weathering?
There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.
What are 5 types of weathering?
These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard.
What are the 4 main types of weathering?
Mechanical weathering is caused by wind, sand, rain, freezing, thawing, and other natural forces that can physically alter rock. Biological weathering is caused by the actions of plants and animals as they grow, nest, and burrow. Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.
What are 5 examples of weathering?
Types of Chemical Weathering
- Carbonation. When you think of carbonation, think carbon! …
- Oxidation. Oxygen causes oxidation. …
- Hydration. This isn’t the hydration used in your body, but it’s similar. …
- Hydrolysis. Water can add to a material to make a new material, or it can dissolve a material to change it. …
- Acidification.
What are 5 physical features?
Landforms include hills, mountains, plateaus, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins.
What are the 6 main types of landscapes?
Here are the main types of natural landscapes: Desert, Plain, Taiga, Tundra, Wetland, Mountain, Mountain range, Cliff, Coast, Littoral zone, Glacier, Polar regions of Earth, Shrubland, Forest, Rainforest, Woodland, Jungle, Moors.
How is geomorphology important?
Geomorphology, as a critical component of physical geography, is needed to understand natural landform changes and potential hazards for populations.
What is base level rivers?
Baselevel is the imaginary horizontal level or surface to which sub-aerial erosion proceeds. It is sea level. Controversy. surrounds the effect of baselevel change on river behavior, the rejuvenation of landscapes, and the delivery of sediment. to the shelf-slope depositional system.
What do you mean by base flow?
Base flow is a portion of the stream flow that is not runoff; it is water from the ground, flowing into the channel over a long time and with a certain delay.
What is the concept of base level?
In geology and geomorphology a base level is the lower limit for an erosion process. … The height of a base level also influences the position of deltas and river terraces.
Who is the first geographer?
Eratosthenes. The first spot has to go to the man who coined the term geography, Eratosthenes (c. 275–194 BC). He created one of the earliest maps of the known world between 276-195 BC, but his greatest contribution was the concept of latitude and longitude.
Who is the most famous geographer?

Who first used the term geomorphology?
However, the word “geomorphology” was first coined and used between the 1870s and 1880s [1] to describe the morphology of the surface of the Earth. But it was popularized by William Morris Davis who proposed the “geographical cycle” also known as “Davis cycle” [2].
What are the 4 types of endogenic processes?
The most familiar endogenic processes involve vulcanism, metamorphism , earthquakes , crustal warping , folding and faulting .
What are the two types of endogenic processes?
Endogenic movements: The energy emanating from within the earth is the main force behind endogenic geomorphic processes. The earth movements are mainly of two types: diastrophism and sudden movements. Diastrophism: All processes that move, elevate or build up portions of the earth’s crust come under diastrophism.
What are the two main geological processes and their differences?
Geologic Processes
Melting – responsible for creating magmas that result in volcanism. Deformation – responsible for earthquakes, volcanism, landslides, subsidence. Isostatic Adjustment due to buoyancy – responsible for earthquakes, landslides, subsidence. Weathering – responsible for landslides, subsidence.
