Chapter 8, Problem 1QP

To determine

Fill the blanks from the given options.

Answer to Problem 1QP

Option (b).

Explanation of Solution

Four principal geological processes that constantly reshape the terrestrial planets are impact, tectonism, volcanism and erosion. Impact cratering causes the most concentrated and sudden release of energy.

Impact cratering, tectonic, and volcanism affect Earth’s surfaced by creating variations in the height of the surface. Erosion is the wearing a way of planet’s surface by mechanical action. Erosion is not only by running water but also by wind and by actions of living organisms, wears down hills, mountains, and craters.

Conclusion:

Since impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down, option (b) is correct.

Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (a) is incorrect.

Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (c) is incorrect.

Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (d) is incorrect.
