2. To identify the changing patterns of the ore deposits of the early Earth.
Calcite exhibits cleavage in three directions.
One example in particular comes to mind. Kimberlite pipes, former explosive conduits for volcanic material, are great sources of the mineral diamond, having ripped apart the mineral from their point of formation deep in the Earth and thrusting them toward the surface. Underground salt domes are virtually unlimited sources of the mineral halite (table salt). The mineral calcite is produced primarily from the sedimentary rock limestone. Sandstone is a primary source of the mineral quartz. Shale deposits are great sources for clay minerals used in ceramics and brick making.
Between 2 and 4. Calcite, which has a hardness of 3, is one example.
Mineral rocks are naturally occurring solid substances with a specific chemical composition and crystal structure. They can be identified by their physical properties such as color, hardness, and luster. Mineral rocks have various uses, including in construction, manufacturing, and jewelry making. They are also important in scientific research and as sources of valuable minerals.
The mineral with a hardness of 2.5-3 and that also functions well as an electrical insulator is gypsum. Gypsum is a soft mineral that can be easily scratched with a fingernail and is used in various industries for its insulating properties in electrical applications.
The mineral with hardness 3 will get scratched.
Because it is derived from biological sources (crops such as rape) and not mineral sources such as coal or oil.
Argentina and Brasil
The cause is the irrational use of fertilizers.
Minerals salts are products of chemical industry or they are extrated from mines.
Add fertiliser, these are artificial sources of minerals for the plant

They can be if you give them a reason to, i.e. water, salt/mineral sources, etc.
Possibly, but they are much too far away for us to reach them.
sources are as follow biological(animal) source plant source mineral source marine source plant tissue culture techniques
Medicine can be derived from plant sources (herbal medicine), animal sources (such as insulin from pigs), mineral sources (like iron supplements), synthetic sources (laboratory-produced drugs), and microbial sources (such as antibiotics produced by fungi or bacteria).
