Cycle of Erosion and Polycyclic Reliefs

Options:

1. Charles Darwin
2. William Morris Davis
3. James Hutton

Correct Answer

Options:

1. The concept that the earth’s history is cyclical
2. The concept that the same physical processes and laws that operate today have always operated throughout geologic time
3. The concept of sequential change in landforms through time

Correct Answer

Options:

1. The concept of uniformitarianism
2. The concept of cyclic nature of the earth’s history
3. The concept of sequential change in landforms through time
4. The process by which exogenetic forces try to remove vertical irregularities created by endogenetic forces
