Introduction Weathering is the breakdown and alteration of rocks and minerals at or near the Earth’s surface into products that are more in equilibrium with the conditions found in this environment. Most rocks and minerals are formed deep within the Earth’s crust where temperatures and pressures differ greatly from the surface. Because the physical and chemical nature of materials formed in the Earth’s interior are characteristically in disequilibrium with conditions occurring on the surface.

Mining is the process of digging beneath surface of the earth and extracting minerals and other useful geological materials. There are two main categories that mines fall into; surface mines and underground mines. Surface mines are effective at extracting minerals and geological materials that are close to the surface of the earth while underground mines are designed to extract minerals and geological materials that are deep beneath the surface of the earth. One of the most common materials that

Mineral and Water Function Minerals are a vital part of the body in many aspects. The functions of minerals vary by the mineral. Some minerals help in developing bone structures such as calcium‚ other assist in energy regulation‚ and some even assist with genetics. The amount of these minerals that the body needs also varies depending on the mineral. There are two types of minerals‚ major minerals and trace elements. We find the minerals that our bodies need from animals and plants‚ the amount of

Globe consumption of mineral raw products ‚ non-metallic minerals‚ particularly sand together with other materials ‚ the largest share . These minerals are broadly distributed ‚ very low rates ‚ typically community manufacturing ‚ the nearest consumption ‚ the

Research task 1 5.1- define the terms mineral and ore with reference to economic and non-economic deposits of natural resources The term ‘ore minerals’ is commonly referred to as economic minerals Mineral: naturally occurring compounds. Rocks are mixtures of various minerals. Most minerals are lattice structures‚ both ionic and covalent. Economic minerals have been divided into two main categories: Metalliferous minerals- mined to extract a metal Industrial mineral- either has some direct practical

1. What is geology and what are the two types of geology? Geology: is the act of studying earth or other solid celestial bodies and how they were formed and what they are comprised of. There are two main types of geology: Physical: the study of minerals and how they were formed. Historical: the study of the story of solid celestial bodies and the evolution of the natural elements/features that comprise them. 2. Explain how a hypothesis is different from a theory. All theories were once hypothesis

you know... Chalcopyrite was the mineral upon which Bronze Age civilizations were built. Within the last century‚ it also became the mineral foundation for our modern electrical age. Our primary source of copper‚ chalcopyrite’s name comes from the Greek words ‘chalkos’ and ‘pyrites’‚ which respectively mean ‘copper’ and ‘striking fire’. With its metallic luster and bright golden color‚ chalcopyrite can fool people into thinking it is gold. It is one of two minerals‚ the other being pyrite‚ that are
