The first one seems the most correct
Minerals are identified according to their properties. One of these properties is their breaking tendency: <em>cleavage</em><em> or </em><em>fracture</em>.<em> Cleavage: Calcite, mica, muscovita, pyroxene. Fracture: Quartz, Asbestos, Limestone.</em>
<u><em>Note</em></u><em>: Since I do not know which your 10 minerals are, I will provide examples of each type according to the breaking tendency.</em>
Many properties of minerals are used to identify them, such as <em>color, density, hardness,</em> among others. In this case, we are talking about their <u>breaking tendency.</u>
<h3 /><h3>How do minerals break?</h3><h3 />
- Minerals can cleave or fracture.
- A type of mineral breaks always in the same, and this is why the breaking tendency is useful to identify them.
<h3 />
<u>- Cleavage</u>
- The mineral breaks in flat smooth planes.
- Cleavage direction and smoothness of surfaces are significant when identifying.
<u>- Fracture</u>
- The mineral break in irregular planes.
- In these minerals, there is no particular breaking direction.
<h2 /><h3>Examples</h3>
<u>- Cleavage</u>
<u>- Fracture</u>

To find your altitude above sea level, you would use an altimeter to find the altitude.
Answer:
There is no actual way that the mantle could be...'exposed' or 'seen'. But scientists have managed to find multiple ways to analyze the mantle and it's actual existence by using multiple devices. The mantle is basically a 2,900 kilometers (1,802 miles) thick blocks of rocks and minerals underneath the crust(or the surface of the earth) , and makes up a whopping 84% of Earth's total volume.
3:they are usually microscopic
