Question

1. which of the following is not a reason that sinkholes form?

a cave ceiling collapses
erosion wears away bedrock.
the water table lowers.
water temperature increases

Explanation:

• Cave ceiling collapse directly forms sinkholes as the ground above caves falls in.
• Erosion of bedrock (especially soluble rock like limestone) creates underground voids that lead to sinkholes.
• A lowering water table reduces support for underground rock, causing collapse into sinkholes.
• Water temperature changes do not contribute to the physical processes that form sinkholes.

Answer:

D. Water temperature increases
