Topic 1.4 · Geography · Geomorphology

Landforms & Their Evolution

Landforms & Their Evolution is studied as part of "Geomorphology" (Physical Geography) in Geography. Geomorphology studies the Earth's interior, rocks and the landforms created by internal and external forces — the base for understanding plateaus, mountains and earthquakes.

In the examination context, landforms & their evolution carries conceptual questions that test both factual recall and analytical understanding. Revise this topic in sequence with the rest of the chapter so that chronological and thematic links are clear.

Important Facts

Epicentre
Surface point directly above the earthquake focus
Layers of the Earth
Crust, mantle, outer core, inner core
Plate tectonics
Movement of lithospheric plates
Igneous rocks
Formed by cooling of magma — e.g. granite, basalt
