Document Summary
Can range from high silicate content to low silicate content. Can be found in plutons and batholiths under the earths surface, but because of. Can be very weak or strong, depending on the ratio of silicates to other minerals. Can be found near volcanoes or volcanic activity. Crystals are made from strong, stable covalently bonded silicate minerals, They form from completely melted rock, called magma. They often rise up into other rock layers because the hot magma rises as it is less dense than the surround rock resulting in very strong rocks. weathering some are seen at the surface. Sediments: physical, chemical, and biological weathering. collect layers of sediments, overtime they form sedimentary rocks. Ingenious rocks can form either in the earth or on the earth, metamorphic rocks only form within the earth. Edi(cid:373)e(cid:374)tary are for(cid:373)ed o(cid:374)ly at the earth"s surfa(cid:272)e.
