Hardness is _____.-the way a mineral breaks under pressure
-the least informative property of a mineral
-measured using the Mohs scale
-the way a mineral splits when stressed

Answers

Answer 1

Answer:

Answer: measured using the Mohs scale

Explanation:

Hardness is defined as ability of the surface to undergo resist deformation.

The degree of hardness is determined by observing the comparative ease or difficulty which which one mineral is scratched by another.

Color is the least informative property of a mineral.

Mohs scale of hardness gives a rating of 1 to talc which is categorized as most soft and rating of 10 to diamond which is categorized as most hard.

Answer 2

Answer:

Hardness is the physical property of mineral measured using the Mohs scale. Hardness is property of mineral to resist scratch. On Mohs scale minerals are classified according to their hardness. Hardest mineral on the scale is Diamond. While the softest mineral is Talc. Different test are done to test the hardness of minerals. These includes, test of scratch from finger nail, test of scratch from knife/blade and test of mineral by a piece of glass. On Mohs scale minerals are classified according to their hardness:

10. Diamond

9. Corundum

8. Topaz

7. Quartz

6. Orthoclase

5. Apatite

4. Fluorite

3. Calcite

2. Gypsum

1. Talc

In which region of the sun does energy move through circulating currents of gases?

Answers

Answer:

the convective zone of the sun

Explanation:

In the the convective zone of the sun the energy is carried upwards by the rising hot gas and subsequently it cools and descends, that is to say that the energy is transported mainly by means of convection.

In this area, circular current patterns are formed where the hot plasma rises and the cold plasma descends.

It's the Convective Zone

after you cut out the drawongs of the rock layers how will u begin the process of sorting the layers by age

Answers

you carbon date them m8

Final answer:

To sort the rock layers by age, you can use the principles of relative dating and correlation, such as the law of superposition and the principle of original horizontality.

Explanation:

After cutting out the drawings of the rock layers, you can begin the process of sorting the layers by age by using the principles of relative dating and correlation. The first principle is the law of superposition, which states that the oldest rock layer is at the bottom and the youngest is at the top. The second principle is the principle of original horizontality, which states that layers of sediment are originally deposited horizontally. By examining the characteristics and relationships between the rock layers, you can determine their relative ages.
