How do you think the hardness and density of a mineral that formed through metamorphism would compare to a mineral that formed through evaporation explained?

How do you think the hardness and density of a mineral that formed through metamorphism would compare to a mineral that formed through evaporation explained?

Minerals that are formed through metamorphism have experienced intense heat and pressure that occur within the Earth’s surface. In this case, it should be harder and denser than those minerals that are formed through evaporation.

How do you think the hardness and density of a mineral that formed through metamorphism would compare to a?

The hardness and density of a mineral that formed by metamorphism is greater than that of the mineral formed by evaporation. The higher the temperature, the denser the mineral is.

Is a substance is a mineral How could you identify what type of mineral it is?

You can identify a mineral by its appearance and other properties. The color and luster describe the appearance of a mineral, and streak describes the color of the powdered mineral. Mohs hardness scale is used to compare the hardness of minerals.

Do you think graphite would most likely display cleavage or fracture explain your answer?

It breaks along irregular surfaces because the bonds between its atoms are about the same strength in every direction. Fracture is a tendency to break into irregular pieces. In graphite, carbon atoms are arranged in layers. Graphite has cleavage because the weak bonds between the layers break easily.

How do you determine if an unknown substance is a mineral?

1. METHODS USED TO IDENTIFYING. MINERALS.
2. CRYSTALS. One of the best ways to identify a mineral is by examining its crystal form (external shape).
3. CLEAVAGE AND FRACTURE.
4. COLOR.
5. The hardness of a mineral can be measured by its resistance to scratching or abrasion.
6. STREAK.
7. LUSTER.
8. SPECIFIC GRAVITY.

How do you know if a substance is a mineral?

What is a mineral?

1. Minerals are naturally occurring. They are not made by humans.
2. Minerals are inorganic. They have never been alive and are not made up from plants or animals.
3. Minerals are solids.
4. Minerals have a definite chemical composition.
5. Minerals have an ordered atomic arrangement.

What characteristics can be used to determine if a substance is a mineral?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

What is the best statement to describe adamantine luster?

Adamantine – Transparent to translucent minerals with a high refractive index yield an adamantine luster, meaning they display extraordinary brilliance and shine.

How property of hardness can be used to help identify minerals?

Hardness. The hardness of a mineral can be tested in several ways. Most commonly, minerals are compared to an object of known hardness using a scratch test – if a nail, for example, can scratch a crystal, than the nail is harder than that mineral.

How do mineral and compositional changes occur during metamorphism?

Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.

Why do you think compaction is excluded in metamorphism?

Changes produced by surface conditions such as compaction are usually excluded. The most important agents of metamorphism include temperature, pressure, and fluids. Resulting rocks have equidimensional grains because of a lack of stress and are usually fine-grained due to the short duration of metamorphism.
