You can classify a substance as a mineral when it is solid, has a crystalline structure, occurs naturally, and has specific chemical composition.
You may get a question about which of the following best defines the relationship between minerals and rocks in different exams.
We will give you a detailed answer with an explanation to help you choose a better option from the list of answers.
Which of the Following Best Defines the Relationship between Minerals and Rocks?
This is a list of the available answer options to the question – Which of the following best defines the relationship between minerals and rocks?
- A mineral consists of atoms arranged in a geometrically repetitive structure; in a rock, the atoms are randomly bonded without any geometric pattern.
- In a mineral, atoms are bonded in a regular, repetitive, internal structure; a rock is a lithified or consolidated aggregate of mineral grains.
- A rock consists of atoms bonded in a regular, geometrically predictable arrangement; a mineral is a consolidated aggregate of rock particles.
- A rock has an orderly, repetitive, geometrical, internal arrangement of minerals; a mineral is a lithified or consolidated aggregate of rocks.
What Is the Difference Between a Rock and a Mineral?
The difference between a rock and a mineral is the composition. Rocks consist of different minerals. The mineral is a naturally occurring substance with a crystalline structure.
It should be solid with a specific chemical composition.
There are different types of minerals.
Feldspar is the most abundant mineral on the earth’s surface.
Quartz is in second place on the list of most abundant minerals on earth.
There are hundreds of types of minerals in the world.
When these minerals combine naturally, you will get a rock.
Rocks form when the minerals combine by pressure or heat.
There are three ways rocks form by combining the minerals.
These ways also help us categorize the rocks based on their formation.
Granite, limestone, and marble are some of the most famous rocks.
What Are Igneous Rocks?
Igneous rocks form when the different minerals melt to combine in the extreme heat of the earth’s core and solidify to make a crystalline form.
All the igneous rocks start their journey in the deep earth’s layers as it provides enough heat to melt the minerals.
These minerals combine as they come towards the top layer of the earth’s surface.
We can divide it into two categories.
If the rock forms inside the deep layer of the earth’s surface, we call it intrusive rock.
You can identify these rocks by large granular structures.
These rocks take thousands of years to come to the earth’s surface as they solidify and give enough time for the crystals in the rock to form.
More time means large crystals. Intrusive igneous rocks have a granular appearance because of that.
These are the rocks with a smooth surface.
When the magma comes near the earth’s surface, it cools rapidly, forming rocks with smooth surfaces.
It is common with volcanic eruptions.
You can find many extrusive igneous rocks near the site of a volcanic eruption.
There is no time to form the large crystals as lava cools very fast. You will get smooth rocks as a result.
What Are Metamorphic Rocks?
These rocks form when new mineral deposits on an existing rock change the rock structure and properties.
These rocks form due to the pressure of the tectonic plates.
Many things can form metamorphic rocks.
Heat, pressure, and mineral fluid are some famous examples.
These rocks get enough pressure and heat to combine without melting.
If the rock melts, we will call it igneous rather than metamorphic rock.
Marble is the most famous metamorphic rock that people use as a building material.
Experts classify different types of metamorphic rocks based on foliation.
You can get foliated and non-foliated rocks in the market.
What Are Sedimentary Rocks?
Sedimentary rocks form when new layers of the minerals deposit on the existing rock from the fluid layer.
These rocks can form from the existing rocks or remains of the living organisms.
There is no need for pressure or heat to form these rocks.
They have one distinct feature that these rocks form on the earth’s surface.
Each rock layer will attach to the existing layer after losing liquid.
The layer attaches to the existing rock like cement.
You can divide these rocks based on the involvement of living organisms.
If the sedimentary rock form with the combination of existing rocks, we call it clastic sedimentary rock.
You can call them biologic sedimentary rock when it forms from the remains of organisms.
Is Glacier Ice a Type of Rock?
Most rocks form with the combination of two or more minerals.
Glaciers are like limestone because they form with one mineral only.
Glacier forms with the process of metamorphism.
Snowfall accumulates snowflakes on the top of the glacier layer.
If there were no glaciers, the bedrock would receive the snowflakes.
More snow will accumulate over the existing snowflakes to put pressure.
Snowflakes have many arms when they fall from the sky.
They combine their arms to make a large crystal structure.
When more snow comes on the top, the crystal structure becomes denser.
We can also call the glaciers a special type of metamorphic rock because it changes the structure of the existing rock with the snowflake combination.
Where Can I Find Information about Mineral Commodities?
You can go to the information about mineral commodities on the United States geological survey website.
There are two sections on the website that specialize in mineral commodity information.
These are excellent sources to know the relationship between minerals and rocks.
You can go to the commodity statistics and information page to get a list of all the minerals.
It is easy to find information about the mineral because the list is arranged alphabetically.
You can visit the international mineral statistics and information to get a list of countries.
You can find information about the minerals in different world locations from this page.
How Do We Extract Minerals?
There are three ways to extract the minerals. Experts classify these methods based on the source location.
- Mining from underground sources
- Mining from surface sources
- Mining from the stream beds
You can consider many factors before selecting a specific method.
The mining cost and the current market price are the crucial methods determining factors.
You cannot use underground mining if the profits are less than the mining costs.
Most experts use the underground mining method for high-quality minerals.
It is also suitable for tubular that go deeper inside the earth.
Surface mining is better for minerals that have a low price tag.
Placer mining is to recover the minerals from the sand and sediments.
Most of the world’s titanium comes from this mining method.
