Worked practice questions

External forces acting on the earth's surface, powered by the sun, are called:

  1. Exogenic
  2. Endogenic
  3. Tectonic
  4. Volcanic
Show answer and solution

Correct answer: A. Exogenic

1. Internal forces are endogenic. 2. External forces are exogenic. 3. They wear down relief and fill basins. _Source: syllabus Fundamentals of Physical Geography, Chapter 6, Geomorphic Processes._

The wearing down of relief by exogenic forces is called:

  1. Epeirogeny
  2. Degradation
  3. Aggradation
  4. Diastrophism
Show answer and solution

Correct answer: B. Degradation

1. Filling up of basins is aggradation. 2. Wearing down is degradation. 3. Together they make up gradation. _Source: syllabus Fundamentals of Physical Geography, Chapter 6, Geomorphic Processes._

  3. Denudational
  4. Depositional
Show answer and solution

Correct answer: A. Endogenic

1. They come from energy inside the earth. 2. Both are endogenic processes. 3. Weathering and erosion are exogenic. _Source: syllabus Fundamentals of Physical Geography, Chapter 6, Geomorphic Processes._
