How Did Minerals Start Out On Earth

from where did the earths water come answers in,mar 13, 2017 secularists believe the earth condensed from clumpy matter flung out of the solar nebula 4.56 or so billion years ago. it was thus originally a hot molten blob that cooled. they used to suggest that most of the water came from inside this cooling earth, but not enough to fill the oceans we have on the earths surface today..environmental risks of mining,environmental hazards are present during every step of the open-pit mining process. hardrock mining exposes rock that has lain unexposed for geological eras. when crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. during separation, residual rock slurries, which are mixtures of pulverized rock and.

    How Did Minerals Form In Our Earth UCSB Science Line

    most of the minerals in the earth have crystallized from something called magma. magma is rock that is so hot that it is liquid instead of solid. when magma cools, the chemical components join together to build minerals. the minerals join together to form a rock. other minerals, like halite (table salt), form when water solutions dry out.
