Rocks and Earth Materials Questions

Multiple choice

What are comets mostly made of?

  1. Dirty ice and dust

  2. Poisonous liquid

  3. Rusty metal

  4. Hot, liquid rock
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Comets are often described as 'dirty snowballs' because they consist primarily of ice, dust, and rocky material that vaporizes as they approach the sun.

Multiple choice

Two examples of surfaces that are NOT easily penetrated.

  1. pumice and clay

  2. granite and pumice

  3. clay and granite

  4. soil and clay
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Clay and granite are both impermeable materials. Clay particles are packed too tightly for water to pass through, and solid granite lacks the interconnected pores needed for permeability.

Multiple choice

Which of the following is NOT a characteristic of earthworks?

  1. They are typically large in scale.

  2. They are often made from natural materials.

  3. They are usually located in a public space.

  4. They are always abstract.

Multiple choice

What is the primary component of stalactites and stalagmites?

  1. Calcium carbonate

  2. Silica

  3. Gypsum

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

Stalactites and stalagmites are composed primarily of calcium carbonate, which is deposited from water seeping through limestone or other carbonate rocks.

Multiple choice

How do stalactites form?

  1. From water dripping from the ceiling of a cave

  2. From water seeping through the walls of a cave

  3. From the evaporation of water in a cave

  4. From the condensation of water vapor in a cave
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Stalactites form when water seeps through the ceiling of a cave and drips onto the floor. As the water evaporates, the calcium carbonate it contains is deposited, forming a stalactite.

Multiple choice

How do stalagmites form?

  1. From water dripping from the ceiling of a cave

  2. From water seeping through the walls of a cave

  3. From the evaporation of water in a cave

  4. From the condensation of water vapor in a cave
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Stalagmites form when water seeps through the walls of a cave and drips onto the floor. As the water evaporates, the calcium carbonate it contains is deposited, forming a stalagmite.

Multiple choice

Which of the following is NOT a type of speleothem?

  1. Stalactite

  2. Stalagmite

  3. Column

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

Soda straws are not speleothems, but rather a type of mineral deposit found in caves.
