Question

In a relatively short period of time, a river has formed a V-shaped valley. Which of the following traits probably characterize the region where the river formed?

A soft bedrock and a dry climate

B hard bedrock and a dry climate

C hard bedrock and a wet climate

D soft bedrock and a wet climate

Answer 1

D - soft bedrock and a wet climate

Wet climate means lots of rain. Lots of rain means running water. Running water erodes ground. Bedrock is soft. Ground erodes at a faster rate. Valley forms in a relatively short period of time.
