Due date: ___________________ Name ___________________________________________ Plate Tectonics Exercise (20 points) PLATE BOUNDARIES There are three different types of lithosphere plate boundaries associated with different types of topographic features and tectonic activity. These are: Divergent boundaries (also called “spreading centers). At divergent boundaries, plates are moving apart. The most common kind of spreading center is the midocean ridge where new ocean floor is created. Spreading

“Volcanic and seismic events are major pieces of evidence towards proving the plate tectonics theory is valid” Discuss the extent you agree with this statement. Plate tectonics is the theory used to explain the structures of the earth’s crust. Direct and indirect evidence can show us what is beneath our feet, or the composition of the crust. Volcanoes and earthquakes are both natural hazards, however are two of the most precise pieces of evidence to explain what is really happening up to 6371

the Continental Drift and the plate tectonics. These theories try to solve the question about the actual position of the continents and how they got there. There are so many terms and information to learn in order to understand these two theories for example plate boundaries, Fault, oceanic floor, volcanoes and more. Plate Boundaries A Plate Boundaries is the location where two plates meet. There are three different plate boundaries. The Divergent plate boundaries are where new crust

Plate tectonics is a process that Withgott and Laposata (2012) say is of extraordinary importance to the planet. The intense heat from the inner core of Earth sends convection currents that flow in a loop in the mantle. This pushes the mantle’s soft rock upwards as it warms and downward as it cools. As this process takes place, it drags these large plates of lithosphere along the surface. The movement of these plates is known as plate tectonics (Withgott & Laposata, 2012). Earth’s surface

meaning all lands in Greek. Many scientists didn’t believe Wegener’s theory of the continental drift back then. Today’s scientists know now that continents sit on massive slabs called tectonic plates. Tectonic plates are constantly interacting and moving called plate tectonics. After a period of time the tectonic activity changes the surface of the earth and reshapes and rearranging the landmasses. The scientific method attempts to explain the phenomena of the universe using a consistent, logical

Rosemary Morrison December 21, 2015 2 The Theory of Plate Tectonics Plate tectonics is the theory that the outer rigid layer of the earth the (lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other. The reason they are able to move is that the molten interior of the earth slowly rises toward the surface. As this hot viscous substance rises it moves the plates like pieces of a puzzle across the globe. Much like an escalator

up the overall region, what structural features that state has, like, mountains and faults. It also includes plate tectonic setting and also an overall geologic map. 3.1. Geologic map: [pic] 3.2. Plate tectonic setting: The middle of the North American tectonic plate actually contains the new Madrid fault zone. One of the attribute of this plate is, this plate is thinner and weaker near to its center. As a result, it formed a rift zone.
