Question
How does time affect the physical weathering of a rock? (1 point)
O Time does not affect physical weathering, only chemical weathering.
O Over time, the rock will become flat, slowing the rate of physical weathering.
• Rock weathers the most when first exposed, then more slowly.
• The longer the rock has been exposed, the more it has weathered.

The correct statement is: **Rock weathers the most when first exposed, then more slowly.**
This indicates that physical weathering tends to be most rapid immediately after exposure to weathering agents (like temperature changes, freeze-thaw cycles, etc.) and that the rate of weathering generally decreases over time as the rock breaks down and the surface area available for further weathering becomes reduced.
