1. For a substance to be a mineral, it has to have certain properties. To begin with, the
substance has to be formed naturally on earth. Secondly, the substance has to be inorganic.
Also, the substance has to be in solid state at room temperature. Substances that qualify as
minerals has to be arranged in a particular manner, it has to be a crystalline and have a
clearly defined chemical composition and a particular surface color, either gold or pyrite.
2. LUSTER
3. SOURCE MAGMA OR LAVA
4. RHYOLITE
5. AT EARTH’S SURFACE ONLY
6. TRUE
7. FALSE
8. Absolute dating, also known as numeric dating, refers to a method of dating that gives
rocks actual dates or date range in the form of numbers of years. Geologists therefore
determine the age of rocks by examining the layers of rocks or fossils. Relative dating,
however, doesn’t provide the actual numerical dates, it only arrang...
