Geology Exam The Earth System (Ch. 1) Asthenosphere (13): Weak/Ductile layer beneath the lithosphere, it deforms to accommodate the movements of plate tectonics Climate System (12): All the earth’s system components that determine climate on a global scale and how it changes with time Earth System (10): All parts of the earth and their interactions Fossil (14): Traces of organisms preserved in the geologic record Geodynamo (14): Sustains earth’s magnetic field, driven by convection in the outer core Geosystem (11): Encompasses terrestrial behavior such as plate tectonics, climate system, and geodynamo Inner Core (8): Inner sphere containing primarily solid iron Lithosphere (13): Strong/Rocky outer shell, comprises the crust and uppermost mantle, forms tectonic plates Magnetic field (13): Region of influence of a magnetized body or an electric current Mantle (8): Between the crust and the core, made up of rocks with intermediate density Outer Core (8): Liquid shell containing liquid iron Plate Tectonic System (13): Lithosphere is broken into large plates that rides on the asthenosphere Uniformitarianism (5): Geological processes today have been working much the same way over time, Present is the key to the past Seismic Wave (6): A ground vibration produced by earthquakes or explosions Topography (4): Varying heights that gives shape to the earth’s surface Plate Tectonics (Ch. 2) Continental Drift (20): Large scale motion of continents across earth’s surface Geodesy (34): Ancient science of measuring the shape of the earth and locating points on its surface Island Arc (28): Linear or arc-shaped chain of volcanic islands formed on the seafloor at a convergent plate boundary Isochron (35): Contour that connects points of equal age on the ocean’s floor as determined by magnetic reversal data Magnetic anomaly (30): Pattern of long narrow bands of high and low magnetic fields on seafloor parallel to the mid-ocean ridge Relative Plate Velocity (31): Velocity at which one plate moves relative to another Rodinia (37): A super continent that formed about 1.1 Ga Subduction (28): Sinking of an oceanic plate beneath and overriding oceanic/continental plate at a convergent boundary

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
