ISB 202 1nd Edition Lecture 5 Outline of Last Lecture I. Antioxidant and redox regulation of gene transcription Outline of Current Lecture II. Structure of the planetIII. Plate TectonicsCurrent LectureStructure of the Planet- Core: solid; nickel and uranium; thermonuclear reactions; produces heat- Mantle: molten liquid rock; plastic; moving- Crust : solid; composed of “plates”; floats on mantle- Crust is made of 3 types of rocko Igneous - graniteo Metamorphic - shaleo Sedimentary - marble- Gradation: Involves Weathering-the disintegration of rock -two typeso Mechanicalo Chemical Erosion Transport Deposition: Sedimentary Rocko Sandstone, limestone, shale- Diastrophism: the movement of solid rockThese 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.o Plates collidingo Creates Folds, Faults, Warps Metamorphic Rock (Heat and Pressure)- Volcanism – the movement of liquid rocko Lava – on surfaceo Magma – below surfaceo Igneous Rock (Basalt, Granit)ePlate Tectonics• Tectonic Plates• 2 Kinds of Plateso Continental: Igneous, Granite, Large Crystals, Less Dense, 30-45 miles thick o Oceanic: Igneous, Basalt, Small Crystals, More Dense, 4-5 miles thick• Plate Boundaries1. Convergent: two plates colliding 2. Divergent: plates moving away from each other3. Transform: plates moving in opposite ways
