Placer depositsIII. Nonmetallic mineral resourcesOutline of Current Lecture I. The solar systemII. Rocks from the skyIII. Neighboring planetsCurrent LectureI. The solar systema. Planets all revolve around the Sun in the same directionb. Three main groupsi. Inner terrestrial/rocky planets1. Iron-rich cores2. Rocky silicate mantle/crust3. The moona. No atmosphere, no active volcanoes or tectonicsb. Many impact cratersi. Highlands: bright, densely-cratered regionsii. Maria: dark regions, smooth lowlandsc. The more craters, the older the surfaceII. Rocks from the skya. Meteoroids when they enter Earth’s atmosphereb. Meteorites when found on Earth’s surfaceIII. Neighboring planetsa. Venusi. Similar to Earth in size, density, locationii. Thick atmosphereiii. 80% of surface: planes covered by volcanic flowsb. MarsThese notes represent a detailed interpretation of the professor’s lecture.
