Document Summary

Igneous rocks: intrusive large crystals, extrusive no crystals, classified by crystal size and composition, know two different types, explain differences and give examples, sedimentary examples, two types. Most are clastic made from other rocks: course gravel (rounded fragments) called conglomerate or gravel (angular fragments) called breccia, medium sand called sandstone, fine mud called siltstone, very fine mud called shale. The continents once fit together pangea: building evidence, ancient mountains, major fault lines, distinctive rock formations, glacial deposits, fossil record, earths magnetic field. Compass needles in ancient basalts from different time periods all pointed in different directions: paleomagnetism: (polar wander, paleomagnetic reversal, volcanoes, formation. Also releases mercury, sulphur dioxide, nitrogen oxides and pm: mined from open put or underground, china is the worlds leading producer, petroleum (crude oil, conventional (liquid, easily accessible) and non conventional (oil sands, deep sea drilling, refineries crude is separated into various constituents.
