Explanation:

A molecular clock determines evolutionary relatedness by examining how many mutations or random changes in DNA, there are between two organisms. When we map the relatedness of different organisms, we are creating a phylogenetic tree. At some point, all organisms that are alive today shared a common ancestor.

Answer:

Minerals can form in all geological environments, which allows them to have a wide range of chemical and physical conditions. Two forms of this are temperature and pressure. There are 4 main categories of mineral formations. Igneous is where the minerals crystalize from a melt. Sedimentary is where the raw materials of the mineral are particles from other rocks that have suffered from erosion and weathering. Metamorphic is where new minerals are created from earlier ones owing to the effects of change. Most of the time it's from increasing temperature and/or pressure. Hydrothermal is where the minerals are chemically precipitated from hot solutions in the earth.
