Rocks And Minerals Quiz
(106).jpg "Rocks And Minerals Quiz - Quiz")
When you see a mineral, there’s a good chance you’ll mistakenly refer to it like a rock. After all, the untrained eye isn’t able to discern the differences when you’re not sure what to look for. In reality, a mineral is naturally occurring inorganic solid while a rock is an aggregate of more than one mineral. What do you know about the two different substances? Take this geographical quiz to find out!
- 1.
Rocks are made of how many minerals put together?
- A.
1
- B.
1 or more
- C.
2 or more
- D.
3
Correct Answer
C. 2 or moreExplanation
Rocks are composed of minerals, which are naturally occurring inorganic substances. The question asks how many minerals are put together to form rocks. Since rocks can be made up of different combinations of minerals, it is correct to say that rocks are made of 2 or more minerals put together.Rate this question:

How does Igneous Rocks form?
- A.
When magma from inside the earth cools
- B.
When lava cools outside of the earth's crust
- C.
From ocean waves
- D.
None of the above
Correct Answer
A. When magma from inside the earth coolsExplanation
Igneous rocks form when magma from inside the earth cools. Magma is molten rock that is located beneath the earth's surface. When it cools and solidifies, it forms igneous rocks. This process can happen either underground or on the earth's surface. If the magma cools underground, it forms intrusive igneous rocks, such as granite. If the magma reaches the earth's surface and cools quickly, it forms extrusive igneous rocks, such as basalt. Therefore, the correct answer is when magma from inside the earth cools.Rate this question:

When Extrusive Igneous Rocks cools really fast what happens?
- A.
It blows up
- B.
Form tiny gas bubbles
- C.
Fossils begin to grow in them
- D.
Gas pockets called vesicles get trapped in the rocks structure
Correct Answer
D. Gas pockets called vesicles get trapped in the rocks structureExplanation
When extrusive igneous rocks cool rapidly, the molten rock solidifies quickly, trapping gas pockets called vesicles within the rock's structure. This occurs because the rapid cooling does not allow enough time for the gas bubbles to escape. As a result, the vesicles become trapped and are preserved in the rock as it solidifies.Rate this question:

Whats the difference between a rock and a mineral?
- A.
There is no difference
- B.
Rocks are more common than minerals
- C.
Mineral is organic solid substance with a definite chemical composition and Atomic arrangement . A rock is a solid mixture of two or more minerals.
- D.
None of the above
Correct Answer
C. Mineral is organic solid substance with a definite chemical composition and Atomic arrangement . A rock is a solid mixture of two or more minerals.Explanation
Minerals and rocks are not the same. A mineral is an inorganic solid substance with a specific chemical composition and atomic arrangement. On the other hand, a rock is a solid mixture of two or more minerals. Therefore, the given answer correctly explains the difference between a rock and a mineral.Rate this question:

What is the most unreliable source to identify a minerals property?
- A.
Streak
- B.
Color
- C.
Luster
- D.
Hardness
Correct Answer
B. ColorExplanation
Color is the most unreliable source to identify a mineral's property because many minerals can have the same or similar colors. For example, both quartz and calcite can be found in various colors such as white, pink, or yellow. Therefore, relying solely on color to determine a mineral's identity can lead to inaccurate results. It is important to consider other properties like streak, luster, and hardness for a more reliable identification.Rate this question:

- 7.
List two factors to produce a metamorphic rock.
