1
To remove only as much land as needed. (Sustainable mining and use of rocks and minerals)
2
Lose of habitat, break of food chain, less biodiversity, dust in the air
3
Crust, mantle, core
4
They are formed by the action of the heat and pressure which causes, chemical changes, physical changes or both. They do not melt
5
Factor affecting the viability of extraction, in which you need to know if the minerals is good and if ithe cost of extraction is high
6
This ones could be environmental, economic or social
7
Process of searching place were to extract rocks and minerals, in which a satélite gives the information to the computer, that processes the information to find the mineral deposit
8
Impact that provides employment
9
Factor affecting the viability of extraction, in which Rodas need to be built in order for trucks to get the pre and commercialized it
10
Surface mining, in which you duh from benches, leave safe walls in order for rocks not to fall, and build roads to take minerals from the overburden
11
Factors affecting the viability of extraction, in which the deposit needs to be big enough to be worth the cost of exploiting
12
Formed when magma cools down and crystallizes. They are exposed to erosion and weathering
13
Noise, water, air and land pollution.
14
Type of sub-surface mining, in which vertical tunnels are dig for the deepest deposits
15
Method of searching for a place were to extract rocks and minerals, in which you look carefully into the ground
16
They are affected by compaction & celebration and formed into sedimentary rocks
17
Center of liquid magma
18
Process in which minerals are extracted from the ground
