Answer: Endogenic systems arise from forces within the Earth, while exogenic systems arise from forces above the Earth's surface
Explanation: Endogenic systems or factors are those that, by their own power, cause processes and actions within the Earth. Exogenic systems are those that by their forces cause processes and actions above the surface and on the surface of the Earth.
Exogenous systems are driven primarily by solar energy, as well as by all forces generated by the action of solar energy, and consequently by the energy of the moon, etc. So, for example, soil erosion is caused by the influence of wind force, then the tide is influenced by the force of the moon, snow, weathering, running water, etc.
Endogenous systems are caused by forces originating from the depths of the Earth. Thus, slow and sudden movements of parts of the Earth's mass below the surface can be induced. For example, volcanoes and earthquakes are sudden movements, while slow movements are tectonic plate movements that contribute to land formation. Slow movements can be horizontal, those that contribute to the formation of mountains, and vertical that contribute to the formation, primarily changes in continental building.
Answer:
This question is actually an English Language question not a Geography question.
The task is to select the option that is most grammatically correct with respect to Subject-Verb agreement and parallelism.
Subject verb agreement simply means the subject and verb must agree in number. This means both need to be singular or both need to be plural.
The Answer therefore is A) <em>core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies of the flow of heat from the inner through the outer planet and of the formation and periodic reversal in direction of Earth's magnetic field</em>
Explanation:
In the line <em>"The discovery is responsible for advancing the studies (1. of the flow of heat 2. of the formation and periodic reversal)"</em>
The first clue is that the subject is the discovery, a singular and therefore the main verb will be "is". So eliminate options C and D.
Option B misses the parallel "of" in the second part.
Option E distorts the parallelism by stating "of how" in the second part
Only option A only maintains the prepositional parallelism
Dusted!
