What is the term for a cave formation that is formed by the deposition of calcium carbonate from dripping water?

  1. Stalagmite

  2. Stalactite

  3. Flowstone

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

A stalactite is a cave formation that is formed by the deposition of calcium carbonate from dripping water. It hangs from the ceiling of a cave and grows downward.

  1. Stalagmite

  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
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil is not a geologic resource because it is not formed from geologic processes. It is formed from the weathering of rocks and minerals and the accumulation of organic matter.

  4. Glass Meteorite
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Glass meteorites are not a common type of meteorite.

Multiple choice

Which of the following is a type of rock that is formed from the cooling and solidification of molten rock?

  1. Igneous rock

  2. Sedimentary rock

  3. Metamorphic rock

  4. Limestone
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Igneous rock is formed from the cooling and solidification of molten rock.

Multiple choice

How can marble quarrying contribute to the release of radioactive materials into the environment?

  1. Through the use of explosives

  2. During the processing of marble

  3. From the weathering of exposed rock surfaces

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Marble quarrying does not typically contribute to the release of radioactive materials into the environment. Radioactive materials are associated with certain types of rocks and minerals, such as uranium and thorium, which are not commonly found in marble deposits.
