Earth scientists have identified over 3000 minerals. These minerals are, however, NONRENEWABLE RESOURCES - their supply is limited and cannot be replaced. RENEWABLE RESOURCES , such as air, water and plants can be replaced within a human lifetime.

NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

Ores form in the crust in a variety of ways. As magma cools, dense METALLIC minerals sink to the BOTTOM . Layers accumulate and form ORE DEPOSITS within the hardened magma. FORMATION OF ORES:

Some ores form through CONTACT METAMORPHISM . Sometimes hot MINERAL SOLUTIONS spread through small cracks in rocks and form bands called VEINS . LODE : A large number of thick mineral veins.

ORES & WATER: The movement of water helps form ore deposits in TWO ways: 1. Streams carry fragments of minerals (i.e. gold) until they get DEPOSITED by weak CURRENTS . Fragments become concentrated and form PLACER DEPOSITS . 2. Water dissolves MINERALS in the earths crust, and then carry the dissolved minerals until it reaches a placer deposit where it accumulates.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
