Q. What are some geological processes?
Geological processes
- Erosion. Erosion involves the movement of rock fragments through gravity, wind, rain, rivers, oceans and glaciers.
- Landforms. Landforms are features on the Earth’s surface that make up the terrain.
- Weathering. Weathering is the wearing down or breaking of rocks while they are in place.
- Deposition.
- Relief.
Q. What was created by an internal process?
Huge amounts of energy, conserved and created near the center of the Earth, are transferred by internal processes to other parts of the globe where they become the forces that create mountain chains, volcanoes and earthquakes.
Q. What do you mean by endogenic processes?
Endogenic processes in geology are a function of a body’s internal geodynamic activity. They comprise volcanic, tectonic, and isostatic processes, which shaped the surfaces of all terrestrial planets, the Moon, and basically all other Solar System bodies with solid surfaces that have been observed in some detail.
Q. What is the difference between exogenic and endogenic processes?
Answer. Answer: It takes place inside the globe and are started by the forces of the Earth. Exogenic processes are forces on or ABOVE Earth’s surface while Endogenic processes are tectonic movements BELOW the surface of the Earth.
Q. How are 7th beaches formed?
Answer: The sea waves deposit sediments along the seashores. This results in the formation of beaches. (vii) What are the ox-bow lakes? Answer: When the river enters the plains, it twists and turns forming large bends known as meanders.
Q. What is dune sand?
A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes form when wind blows sand into a sheltered area behind an obstacle. Dunes grow as grains of sand accumulate.
Q. Which is not an erosional feature of sea waves Class 7?
Sea beaches are not the erosional feature of sea waves. They are formed due to the depositional activities of sea waves.
Q. What do you mean by sea caves?
Sea cave, cave formed in a cliff by wave action of an ocean or lake. Sea caves occur on almost every cliffed headland or coast where the waves break directly on a rock cliff and are formed by mechanical erosion rather than the chemical solution process that is responsible for the majority of inland caves.
