Weathering is wearing down objects by elements in an environment
B) Most metals conduct heat readily. In pure elemental forms, they
neither have basic or acidic properties. Other properties include
malleability, high melting points, high densities, and electric
conduction.
The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
