Which of the following is an example of the wind slowly causing changes in Earth's landforms?(1 point)
Responses
A. Dangerous crosswinds force a car off the road.
B. A hurricane blows the roof off a house.
.
C. Hot gas blasts out of a volcano.
D. The wind wears down and smoothes rocky hills over time.
The correct answer is D. The wind wears down and smoothes rocky hills over time. To determine the correct answer, we need to understand how wind can cause changes in Earth's landforms.
The process of wind wearing down and smoothing rocky hills is known as erosion. When wind blows over rock surfaces, it carries small particles of sediment, like sand and dust, which can act as natural abrasives. Over time, these particles can wear away at the rock, causing it to become smoother and potentially changing its shape.
To arrive at this answer, we need to consider the other options and eliminate them:
A. Dangerous crosswinds force a car off the road - While this scenario involves wind, it does not relate to slow changes in Earth's landforms caused by wind. It describes a sudden, possibly dangerous event caused by wind, rather than gradual changes over time.
B. A hurricane blows the roof off a house - This option refers to the destructive power of a hurricane, which is a severe and intense windstorm. While hurricanes can cause significant changes in the landscape, such as beach erosion or coastal reshaping, it does not represent the slow, gradual changes mentioned in the question.
C. Hot gas blasts out of a volcano - This option refers to volcanic activity rather than the slow changes caused by wind. Volcanic eruptions can bring about immediate changes in landforms, as molten rocks, ash, and gas are forcefully expelled.
Therefore, option D is the correct answer as it aligns with the given description of the wind slowly causing changes in Earth's landforms through erosion.
