Geomorphology MCQ 1

Answer: b) Latitude
Explanation:  Latitude is the most fundamental control of climate because it determines the angle at which the sun's rays strike the Earth, which in turn determines the amount of solar energy (insolation) a region receives. This establishes the basic pattern of global temperature zones (tropical, temperate, polar).

20. Fjords, such as those in Norway, are deep glacial valleys that have been:
a) Excavated by wind erosion.
b) Submerged by a rise in sea level.
c) Created by volcanic activity.
d) Formed by river deposition.

Answer: b) Submerged by a rise in sea level.
Explanation:  Fjords are U-shaped valleys carved by the immense erosive power of glaciers. After the glaciers retreated at the end of the last ice age, global sea levels rose, flooding these deep valleys with seawater to create the dramatic, steep-sided inlets known as fjords.
