Question 1

What are the main types of earth movements?

Accepted Answer

The main types of earth movements are endogenetic forces (internal) and exogenetic forces (external). Endogenetic forces include diastrophic movements like epeirogenic and orogenic movements, plus sudden movements like earthquakes and volcanic eruptions. Exogenetic forces comprise weathering, erosion, and deposition driven by external agents like water, wind, and ice.

Question 2

How do endogenetic forces differ from exogenetic forces?

Accepted Answer

Endogenetic forces originate from within the Earth due to tectonic activity, magma movement, and gravitational forces, creating major landforms like mountains and continents. Exogenetic forces act on the Earth's surface powered by solar energy, atmosphere, and hydrosphere, wearing down and reshaping landforms through weathering, erosion, and deposition.

Question 3

Why is earth movements classification important for UPSC preparation?

Accepted Answer

Earth movements classification is a core topic in UPSC Geography Optional and General Studies Paper-1. It explains landform evolution, natural hazards like earthquakes and volcanoes, and geological processes. Questions on diastrophic movements, mountain building, and denudation processes appear regularly, making conceptual clarity essential for scoring well.
