3.Plate Tectonic Theory & Continental Drift Theory Flashcards
What are the two types of forces affecting Earth’s crust?
The two types of forces affecting Earth’s crust are exogenic forces and endogenic forces.
What are endogenic forces?
Endogenic forces are internal forces that originate from within the Earth. They lead to the vertical movement of the Earth and the formation of faults and folds.
What are epeirogenetic forces?
Epeirogenetic forces are a type of endogenic force that leads to the vertical movement of the Earth’s crust.
What are orogenic forces?
Orogenic forces are a type of endogenic force that leads to the formation of faults and folds, and horizontal movement. They are responsible for the development of mountains.
What is the meaning of “Oro” in orogenic forces?
“Oro” means mountain in orogenic forces.
What type of forces lead to the formation of faulting mountains?
Tensional forces on the Earth’s crust lead to the formation of faulting mountains.
What is an example of faulting mountains?
Vindhya and Satpura mountains are examples of faulting mountains.
What type of forces lead to the formation of folded mountains?
Compressional forces on the Earth’s crust lead to the formation of folded mountains.
What is an example of folded mountains?
The Himalayan mountains are an example of folded mountains.
What are exogenic forces?
Exogenic forces are external forces that originate from the Earth’s atmosphere and lead to the degradation or aggradation of Earth’s surface.
What is the difference between exogenic forces and endogenic forces?
Exogenic forces originate from outside the Earth’s crust, while endogenic forces originate from within the Earth’s crust.
What is the effect of exogenic forces on Earth’s surface?
Exogenic forces cause the wearing down (degradation) of relief/elevations and filling up (aggradation) of basins/depressions on Earth’s surface.
What is denudation?
Denudation is the process of removing rock or soil from the Earth’s surface through erosion by natural agents such as rivers, glaciers, winds, sea waves, and underground water.
How do exogenic forces flatten the Earth’s surface?
Exogenic forces flatten the Earth’s surface through denudation, which removes rock and soil from elevated areas and deposits them in lower areas.
What are the three types of procedures that take place in exogenic forces?
The three types of procedures that take place in exogenic forces are weathering, denudation, and deposition.
What is weathering?
Weathering is the physical or chemical breakdown of rocks on the Earth’s surface due to exposure to atmospheric agents such as air, water, and temperature changes.
What is deposition?
Deposition is the process of depositing sediment or other materials that have been eroded and transported by natural agents such as rivers, winds, and glaciers.
What type of movement occurs in orogenic forces?
Horizontal movement occurs in orogenic forces.
How do orogenic forces lead to the development of mountains?
Orogenic forces lead to the development of mountains by causing horizontal movement that results in the formation of faults and folds.
What are the two types of mountains that can form due to orogenic forces?
The two types of mountains that can form due to orogenic forces are faulting mountains and folded mountains.
What are tensional forces, and what type of mountains do they lead to?
Tensional forces are forces that pull the Earth’s crust apart. They lead to the formation of faulting mountains. Examples of faulting mountains include Vindhya and Satpura mountains.
What are compressional forces, and what type of mountains do they lead to?
Compressional forces are forces that push the Earth’s crust together. They lead to the formation of folded mountains. An example of folded mountains is the Himalayan mountains.
How are faulting mountains formed due to orogenic forces?
Faulting mountains are formed due to orogenic forces through tensional forces that pull the Earth’s crust apart, leading to the formation of faults.
How are folded mountains formed due to orogenic forces?
Folded mountains are formed due to orogenic forces through compressional forces that push the Earth’s crust together, leading to the formation of folds.
