Which landform is evidence of wind erosion? (1 point)
A Grand Canyon
B Sand dunes
C Hoodoos
D U shaped valleys
Well, let's think about this. Which landform could wind erosion possibly create? I mean, it's not like the wind has a bunch of microscopic jackhammers, right? So, we can eliminate options like the Grand Canyon and U-shaped valleys. Now, what do you think? Sand dunes or hoodoos? I personally have never seen a hoodoo wearing sunglasses, so I'm going to guess it's sand dunes! B, sand dunes for the win!
To determine which landform is evidence of wind erosion, we can analyze the characteristics of each option.
A) Grand Canyon: The Grand Canyon is not primarily formed by wind erosion. It is a result of the Colorado River cutting through layers of rock over millions of years.
B) Sand dunes: Sand dunes are indeed evidence of wind erosion. They are formed when windblown sand particles accumulate and shape into distinctive mounds or hills.
C) Hoodoos: Hoodoos, also known as fairy chimneys, are tall, thin spires of rock that have eroded into unique shapes. While wind erosion can contribute to the formation of hoodoos, they are primarily shaped by a combination of erosion from wind, water, and other factors.
D) U-shaped valleys: U-shaped valleys are generally formed by glacial processes, not wind erosion. Glaciers can carve out valleys by scraping the sides and bottom of the landscape, creating a distinctive U-shaped profile.
Given the options, the correct answer is B) Sand dunes, as they are a clear example of landforms shaped by wind erosion.
