Which of the following is NOT a potential resource that could be extracted from extraterrestrial bodies?
-
Water
-
Oxygen
-
Helium-3
-
Rare Earth Elements
D
Correct answer
Explanation
Rare Earth Elements are not typically found in large quantities on extraterrestrial bodies, making them less feasible to extract.
What is the process of extracting valuable minerals or other geological materials from the Earth?
-
Mining
-
Quarrying
-
Excavation
-
Drilling
A
Correct answer
Explanation
Mining is the process of extracting valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, or reef.
What are the two main types of mining?
-
Surface mining and underground mining
-
Open-pit mining and strip mining
-
Quarrying and dredging
-
Placer mining and lode mining
A
Correct answer
Explanation
The two main types of mining are surface mining, which involves extracting minerals from the Earth's surface, and underground mining, which involves extracting minerals from beneath the Earth's surface.

-
Surface mining
-
Underground mining
-
Both are equally environmentally friendly
-
Neither is environmentally friendly
B
Correct answer
Explanation
Underground mining is generally considered to be more environmentally friendly than surface mining because it disturbs less land and produces less waste.
