How does a volcanic plateau change the surface of the Earth?

Answer 1

The effect of internal forces and external forces on the formation of landforms

Volcanoes and earthquakes are all internal forces.

Volcanic geomorphological effects for the lies in Sediment Formation volcanic cone volcanic landforms. Namely the crustal magma erupted accumulation into mountain form -- volcanoes. Around, larger volcano relative height of up to 4000 to 5000 meters, the crater diameter of up to hundreds of meters. As the Soviet Union worthy of observation of the peninsula g to stay Qifu volcano relative height of 4572 meters, the diameter of the crater for 625 meters. Smaller volcanoes, relative height is less than 100 meters. Volcanic sometimes clumped distribution, said Volcanic Group.

Earthquake for geomorphological effects without fixed mode, formation can be formed mountains and Rift Valley, depression, resulted in the increase of the earth's surface rolling.

Answer 2

Earthquakes and volcanic eruptions have changed the forces of the terrain from internal forces, such as the movement of the earth's crust.

The earth's internal forces from the thermal, chemical, energy and gravity. The earth rotation can be generated by the inner earth these forces, known as internal forces of the earth. The mainland on the mountain, plateau, basin, terrain, sea, ocean bottom ridge trench, forming process, plays a leading role force the role of internal forces. A variety of forms, mainly in the depths of the earth crustal movement, magmatic activity and earthquakes. Folds and faults are important evidence of crustal movement in the crust caused by internal forces, it makes the crustal deformation into ridge, valley and basin. In force can form the continent and ocean, can form mountains and Rift Valley, the ups and downs of depression, the surface of the earth is increasing.
