Theory of Plate Tectonics

The crust of the Earth is divided into pieces. These are called tectonic pieces tectonic plates crustal slices Which of the following is not a type of crust? continental oceanic mountainitic What causes movement of the plates? Conduction of heat within the Earth's core Convection currents in the mantle Radiation of heat from the Sun Convection currents flow according to the following process: hot molten rock rises cool molten rock sinks cold molten rock rises hot molten rock sinks Identify the three types of plate boundaries. (SPELLING COUNTS!) Using the word list, fill in the blanks on the picture. Each word is used only once and SPELLING COUNTS! divergent transform convergent divergent convergent transform Read the following passage about plate boundaries and fill in the blanks using the word bank. (SPELLING COUNTS!) The border between two tectonic plates is called a boundary. All the tectonic plates are constantly moving — very slowly — around the planet, but in many different directions. Because of these differences, tectonic plate boundaries are grouped into three main types.A convergent boundary occurs where two plates are pushing toward each other (colliding).A divergent boundary marks two plates that are moving apart from each other (dividing).A transform boundary occurs where two plates slide past each other. Sea-floor spreading, mid-ocean ridges, and rift valleys all form along which type of plate boundary? Divergent Convergent Transform Mountains, subduction, and trenches all form along which type of plate boundary? Divergent Convergent Transform Crust is neither created nor destroyed along this tectonic plate boundary. Divergent Convergent Transform The crust and the uppermost part of the mantle is called the lithosphere asthenosphere outer rim
