Greasy-appearance of being coated w/ oily substance… Silky-sheen of fibrous materials such as silk.. Resinous- example amber. Hardness Refers to "scratchability" or resistance to being scratched. Harder minerals will scratch softer minerals. Geologists rank minerals according to hardness using the Moh’s scale. The following is a listing of the minerals of the Mohs scale and their rating: 1. Talc –softest mineral 6. Orthoclase Feldspar 2. Gypsum

mysteries like the movements of continents‚ form of the ocean floor‚ mountain chains‚ volcanoes‚ earthquakes‚ and how ancient life was sorted over time. Determining the behavior of the Earth’s crust‚ from plate tectonics‚ it made it easier for Geologist to focus more on the strange things that happen below the Earth’s surface. Many of the hotspots around the world were apparent to the first theorists. When the theorists sketched the crustal plates on the globe‚ they saw the world’s volcanoes fall

Zooplankton subsist on a diet of phytoplankton‚ which‚ in turn‚ rely upon the energy of the sun to produce organic matter and energy through photosynthesis. • Once a potential natural gas deposit has been located by a team of exploration geologists and geophysicists‚ it is up to a team of drilling experts to dig down to where the natural gas is thought to exist. This section will describe the process of drilling for natural gas‚ both onshore and offshore. Although the process of digging deep

Geology started out with the simple curiosity of the earth‚ its rocks‚ how and when they formed. “William Strata Smith first recognized in the early 1800s that the fossil record had systematically changed through time.” This lead scientists‚ namely geologists from all over the world to make divisions of geological time known as a relative time scale. In order to get a generalized date they placed rocks and fossils into eras and periods. With a relative time scale‚ scientists were able to work together
