Select All What are the limitations of a map? Size, shape, land features and color What are the limitations of a globe? shape, size, color, and land features What are the limitations of a fault model? size of the plates, shape, color, where it is, what direction the land masses move and land features around the fault What are the limitations of a layers of the earth picture size (of the whole thing and the layers), color What is the tectonic theory? A theory that the world was made of a single continent through most of geologic time Who developed the theory of the continental drift? Alfred Wegner If the plates continue to move and in time what will happen to the lay out of the earth? Sometime in the future the continents will come back together in the Pacific ocean, if the continents keep moving Explain convection currents and its relationship with tectonic plate movement In the asthenosphere the gooey substance circulates just like convection currents, with hot substances going to the top of the layer of the atmosphere and cooling down, then coming back to the bottom of the layer of the atmosphere and warming it up, then sending it back up over and over and over again. What is a divergent boundary? What land features are formed by a divergent boundary? Two or more plates pull away from each other and new crust is created. Also water, wear available, may fill in the space between the two masses. DIVIDE What is a transform boundary? What land features are formed by a transform boundary? When plates slip past each other and create great amount of friction. Crust is not created, crust is not destroyed. Major earthquake starter What is a convergent boundary? What land features are formed by a convergent boundary? Two masses COLLIDE. One of the masses goes down, in to the ground while the other makes mountains and volcanoes How do earthquakes occur and what causes them? An earthquake happens when two plates form a transform, convergent or divergent boundary. It is mainly started by a transform boundary. What is weathering? The breaking down and weathering away of rock material What is erosion? The transfer of rock material to another location, also known as carrying away What is deposition? something that is deposited What is chemical weathering The breaking down of the chemical components of a rock; Chemical change What is Physical weathering The breaking up of rock material into smaller pieces What is the definition of longitude? Angular distance east or west on the earth's surface, measured by the angle contained between the meridian of a particular place, as that of Greenwich, England, and expressed either in degrees of by some corresponding difference in time. What is the definition of latitude? The angular distance, north to south from the equator a point on the earth's surface, measured on the meridian of the point What is the definition of relative? something having, or standing in, some relation to something else What is the definition of describes? To trace the form or outline of What is the definition of model (like a map)? A small object, usually built to scale, that represents in detail another, often larger object What is the definition of limitation? The act of limiting or the state of being limited What is the definition of rate? A magnitude or frequency relative to a time unit What is the definition of conclusion? a result, issue, or outcome What is the definition of illustration? something that illustrates another object What is the definition of composed? be part of construction What is the definition of deformed? Distorted in form; misshapen What is the definition of effect? The power to produce an outcome or achieve a result; influence What is the definition of characteristic? a distinguishing feature or quality What is the definition of feature (land)? mountains and other important things on the earth's surface
