Endogenic and exogenic forces

Q: In which situation is the effect of endogenic forces more clearly visible than that of exogenic forces?

Sudden uplift of land by an earthquake An earthquake is a sudden endogenic event linked with internal energy of the earth. Exam tip: connect sudden relief change with endogenic force.

Q: In which process is the main energy source considered heat and pressure inside the earth?

Folding and faulting Folding and faulting are produced by internal stresses of the earth. Exam tip: decide the process category by checking the energy source.

Q: Uplift of a plateau followed by deep valleys along its margins shows which sequence?

Endogenic uplift first and then exogenic erosion Plateau uplift is endogenic and valley cutting is exogenic erosion. Exam tip: pay attention to the sequence of events.

Q: Which pair correctly shows the difference between endogenic and exogenic forces?

Volcanism and river erosion Volcanism is endogenic while river erosion is exogenic. Exam tip: keep examples of each category clear.

Q: The intensity of exogenic processes is most strongly influenced by which factor?

Local climate and slope Climate affects weathering and runoff while slope increases erosion rate. Exam tip: link exogenic processes with external conditions.

Q: When rock breaks or decomposes without movement from its place then it is part of which exogenic stage?

Weathering In weathering rock breaks or chemically changes in place. Exam tip: remember the difference between weathering and erosion.

In this Class 11 Geography topic from the chapter Geomorphic Processes, students learn how endogenic forces originate within the Earth and shape its surface through tectonic movements, folding, faulting, earthquakes, and volcanism. They also examine exogenic forces acting at or near the surface, including weathering, erosion, mass movement, and deposition. The topic explains how these internal and external processes interact over time to create and modify landforms such as mountains, valleys, plains, and plateaus.

Answer and explanation

Correct answer: A. Endogenic forces create relief and exogenic forces modify it

Endogenic forces create relief and irregularities while exogenic forces erode and level them. Exam tip: remember both source and effect.
