FANR 3060 1st Edition Lecture 1Outline of Current LectureI. LandscapesII. The Rock Cycle (Fig. 1.1)III. Structure of the Earth’s Interior (Fig. 1.2)Chapter 1I. Landscapesa. Unit of land surface characteristics by distinct/uniform topographyi. i.e. a watershed is a landscape that drains all water to a single water sourceb. More or less the typical geology/geologic history, soil types, and hydrologic conditions of a certain area i. Hydrologic conditions (climate)ii. Soil is a function of geologic history and hydrologyc. also has to do with elevation changei. flatlands (plains), steeplands (mountains) and rollingd. Landscape formationi. How did it get that way?1. Geologic history2. Underlying rock types3. Climate (erosion/deposition)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.II. See Fig. 1.1, “The Rock Cycle”a. Rock : naturally occurring hunk of mineralsi. Minerals: naturally occurring compounds with certain chemical compositions1. Primarya. Come from magmab. Feldspar, quartz2. Secondarya. Created from decomposition and deposition of primary mineralsii. Originally, all rocks were igneous (ig.)1. Igneous rock is made from primary mineralsa. Ex. granite2. Magma = molten rockb. Water evaporates out of ig. rocks as they cool down, which results in clouds, and then precipitationc. Weathering (by rain)i. Bits of weathered rock get washed into oceanii. These formed piles, got compressed, and turned into sedimentary rocks 1. i.e. limestoned. Metamorphic Rocki. Partial re-melting of rocksIII. Fig. 1.2, “Structure of the Earth’s Interior”a. Hot spotsi. Pushes magma through crust1. This is what islands are made of2. Hawaii is one big igneous rockb. The Earth’s Crusti. ~20 miles thickii. Rigid structureiii. Broken into plates that are movingiv. When plates collide1. Volcanoes, earthquakes2. Causes regional metamorphism3. Big mountains are made when plates collide, not just push over/under one anotherc. The Mantlei. Right below the crustii. Has a plastic behavior1. Flowable; deforms under pressured. The Corei. Thousands of miles thickii. Liquid1. Gravitational force and
