Geological Agents

Question 1

Those which derive their energy from external sources and ultimately from the sun

Answer 1

Exogenous Processes

Question 2

Geologic agents that originate from the earth’s surface

Answer 2

Epigene

Question 3

Those that originate from within the earth’s crust

Answer 3

Endogenous Processes

Question 4

Geologic agents that originate underneath the earth’s crust

Answer 4

Hypogene

Question 5

It is an epigene geologic agent with a three fold process. Process by which the original irregularities of the earth’s surface are removed and creates a levelled surface.

Answer 5

Gradation

Question 6

What’s the 3-fold process of gradation

Answer 6

1. The surface is decayed and eroded
2. Products of this decay and erosion are transported
3. Deposited at usually lower levels

Question 7

Two major categories of Gradation

Answer 7

1. Degradation
2. Aggradation

Question 8

Material from a high relief feature is removed by exogenous or external processes

Answer 8

Degradation

Question 9

Factors affecting degradation

Answer 9

1.Properties of the material on which the process is operating
2. Energy available
3. tools used by the agents

Question 10

Process of elevation of low-lying tracts thru depositions of materials, by various epigene geological agents

Answer 10

Aggradation

Question 11

Two main endogenous processes

Answer 11

Volcanism and Diastrophism

Question 12

Elevates or builds up the portions of the earth’s surface

Answer 12

Diastrophism

Question 13

2 types of diastrophism

Answer 13

1. Orogenic
2. Epeirogenic

Question 14

Refers to mountain building with deformation of the Earth’s crust

Answer 14

Orogeny

Question 15

Refers to regional uplift without marked deformation

Answer 15

Epeirogeny
