The way minerals break is called cleavage. In mica for example, there is a platy cleavage thanks to the atomic structure which allows it to break along flat, parallel surfaces. Quartz on the other hand has no cleavage so just breaks along irregular surfaces.

Cleavage of the mineral causes breakage of minerals unevenly along flat surfaces.

<u>Explanation: </u>

Cleavage refers to breaking of flat surface minerals into many surface. The crystalline structure of mineral determines the cleavage. It is the ability of crystalline materials to divide into “definite crystallographic structural planes”.  

The permanent locations of atoms and ions in crystal are the main reason for the relative weakness, which forms smooth repeating surfaces. They are visible both in the microscope and to naked eye.

Deforestation is a big deal. Who benefits? Who loses?, Do the benefits outweigh the costs? Are there any alternatives to current
VladimirAG [237]

The deforestation generally brings loses, and the costs outweigh the benefits, though there are some methods that can turn things around.

Explanation:

The deforestation is a huge problem. It occurs because of the human activities, be it agriculture, mining, industry, expending cities etc. While all these things are benefiting the humans on the short run, on the long run it is devastating. The soil is not of good enough quality, so it can be used only for few years, the mining causes enormous pollution which is destroying the environment on the long run, same is done by the industry, and the cities bring in all sorts of problems, always bringing in big losses for nature.

There are alternatives though, as the forests can be used and to benefit humanity, but also to remain in good condition, and with it the ecosystems. When the trees are cut, same number of trees should be planted on the same places, thus making the forests sustainable. Also, fruit forests can be created gradually, and they will provide both the humans and animals with free and organic food in abundance. This matters a lot because if methods like this are not implemented, the forests will disappear, ecosystems will be destroyed, the humans will be left without lot of resources, and there will dramatic changes of all sorts on the planet, all of which negative.

Forests that are being constantly cut down and are getting destroyed are:

  • Amazon rainforest
  • The Congo rainforest
  • The rainforests of Southeast Asia
