Question

Explain briefly the landforms created by volcanoes on the surface of the earth.

Answer 1

The landforms created on the earth’s surface are called extrusive landforms. These include volcanic plateaus, volcanic mountains, and volcanic plains.

1. Volcanic Plateaus: These are derived from lava which flows from volcanic eruptions. The Plateau of Peninsular India, especially the northwestern Deccan, is an example of a lava plateau. Other examples are the South African plateau, the Colombian plateau and the Ethiopian plateau.
2. Volcanic Mountains: These mountains are built from material ejected from the fissures in the earth’s crust. Volcanic mountains are the most diverse because there are great differences in volcanic eruptions as well as the materials they throw up.
3. Volcanic Plains: These plains are vast and smooth formed by extensive volcanic flooding from volcanic centres. The Western Victorian Plains in Victoria, Australia, are the finest examples of volcanic plains.
