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

Igneous rocks are formed from the cooling and solidification of molten rock, either above or below the Earth's surface.

Multiple choice

Which type of rock is formed when existing rocks are subjected to high temperatures and pressures?

  1. Igneous

  2. Sedimentary

  3. Metamorphic

  4. Foliated

  5. Non-foliated
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Metamorphic rocks are formed when existing rocks are subjected to high temperatures and pressures, causing changes in their mineral composition and texture.

Multiple choice

What is the term for the flat, sheet-like structure found in some metamorphic rocks?

  1. Foliation

  2. Cleavage

  3. Lamination

  4. Banding

  5. Schistosity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Foliation is the term for the flat, sheet-like structure found in some metamorphic rocks, resulting from the alignment of minerals during metamorphism.

Multiple choice

What is the most common type of deep geological repository for nuclear waste?

  1. Hard rock repository

  2. Clay repository

  3. Salt repository

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

The most common type of deep geological repository for nuclear waste is a hard rock repository. Hard rock repositories are located in stable geological formations, such as granite or gneiss. Hard rock repositories are designed to isolate nuclear waste from the environment for thousands of years.
