  2. Stalactite

  3. Flowstone

  4. Soda straw
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A soda straw is a cave formation that is formed by the deposition of calcium carbonate from capillary action. It is a thin, hollow tube that typically grows from the ceiling of a cave.

Multiple choice

Which of the following is NOT a type of geologic resource?

  1. Minerals

  2. Fossil fuels

  3. Water

  4. Soil
