Physical Weathering is caused by all but which of the following?
what are your answer choices
brb you post the answer choices and when i get back i will help you
To determine which option is not a cause of physical weathering, we need to understand what physical weathering is.
Physical weathering, also known as mechanical weathering, is the process of breaking down rocks and minerals into smaller pieces without changing their chemical composition. It is caused by various external factors that physically break down the rocks.
The options we have are:
A) Water freezing and expanding
B) Plant and tree roots penetrating rocks
C) Acid rain dissolving minerals
D) Wind erosion
To find the answer, we can eliminate the options that are known causes of physical weathering.
Option A, water freezing and expanding, is a well-known cause of physical weathering. When water seeps into cracks in rocks and freezes, it expands, causing the rock to crack and break apart. This is a form of physical weathering.
Option B, plant and tree roots penetrating rocks, is also a cause of physical weathering. As roots grow, they can exert pressure on rocks, causing them to crack and break apart.
Option C, acid rain dissolving minerals, is another cause of physical weathering. Acid rain, which contains acidic components due to pollution, can react with minerals in rocks, dissolving them over time and breaking them down physically.
Based on this information, we can conclude that option D, wind erosion, is the correct answer. Wind erosion refers to the process of wind carrying away particles of sand, soil, or other loose materials, rather than breaking down rocks physically. While wind erosion can transport already-weathered particles, it is not a direct cause of physical weathering.
Therefore, the answer is D) Wind erosion.
