Intro & Maps for $100 1.Geology 2.Astronomy 3.Oceanography 4.Meteorology What is the name of our galaxy? The Milky Way galaxy Alfred Wegener is credited with the idea of ??????? Continental Drift What is the difference between a fracture and a fault? A fracture is just a crack in the ground, but a fault is when there is movement along the fracture. What are the three main types of volcanoes? 1. Shield Volcano 2. Cinder Cone Volcano 3. Composite Volcano (aka stratovolcano) What determines whether a rock is igneous, sedimentary or metamorphic? The way that it is formed. Which metric unit would be appropriate to give the distance from Cary to Greensboro? kilometers Which scientist invented the telescope? Galileo Earth’s many lithospheric plates float on the ????? asthenosphere Where is the foot wall of a fault located? BELOW the fault Mt. St. Helen’s is an example of which type of volcano? Composite Cone What are the two types of igneous rocks? Intrusive Extrusive What process do scientists use to solve problems? Scientific Method Our sun is in what phase of its life cycle? Main Sequence Star What is the action at a divergent boundary? AND Give an example of where this type boundary is found. Plates are pulling apart. Ex. mid-ocean ridges What does the hanging wall do in a reverse fault? The hanging wall moves UP. Name & describe three types of mafic lava. Pahoehoe – wrinkled, ropey Aa – sharp, jagged chunks Pillow Lava – globs of lava that are extruded underwater What determines the difference between the clastic sedimentary rocks? Size of the particles ex. Large = conglomerate Medium = sandstone Small = shale Which branch of earth science studies meteors that streak across the sky? Astronomy Explain the differences between a meteor, a meteorite, and a meteoroid. Meteoroid – located in space Meteor – has entered Earth’s atmosphere Meteorite – has crash-landed onto Earth What features are formed at a oceanic-to-oceanic convergent boundary AND where could you see such a boundary? Trench and a volcanic island arc ex. Aleutian Islands and Japanese Islands Name the three major earthquake zones? 1. Mid-Ocean Ridges 2. Pacific Ring of Fire 3. Eurasian-Melanesian Belt Which types of tephra can be carried by the global winds and distributed worldwide? Volcanic dust and ash What are the two ways that metamorphic rocks can be formed? Regional metamorphism Contact metamorphism A student wants to determine which color absorbs heat the most. The experiment has many different colors of paper under a lamp and the temperature of each is recorded. Name the Independent Variable. Name the Dependent Variable. Independent Variable: different colors Dependent Variable: temperature Name and explain the theory about how our universe began. The Big Bang Theory states that all the matter of our universe began in one tiny point. There was some type of explosion and all that matter and energy was flung outward and created our expanding universe. Name the three types of plate boundaries and give the type of stress associated with each. 1. Divergent Boundary – stress 2. Convergent Boundary – compression 3. Transform Boundary -shearing Name at least three ways that earthquakes might be predicted. 1. The ground tilting 2. Small foreshocks 3. Seismic gap theory Explain the difference between a crater and a caldera. A crater is a funnel-shaped pit at the top of the volcano. A caldera is a bowl-shaped depression created when the walls of the crater collapse. What is the difference between a foliated and nonfoliated metamorphic rock? Foliated has a striped (or banded) appearance. Nonfoliated does not have stripes (or bands).
