Name Period Date Plate Tectonics, Continental Drift, and Seafloor Spreading Study Guide Answer the questions using the assignments in your science notebook. Write down which assignment helped you find the answer. Question What is any trace of an ancient organism preserved in rock? What is the word for what happens when tectonic plates move at any kind of boundary? What is another name for a colliding boundary? What is the word that describes when one tectonic plate slides beneath another? What is the amount of mass in a given volume? What happens to hot material and cold material when in the same container? What is the form of heat transfer in Earth's mantle which causes tectonic plates to move? What is the canyon-like feature which forms at a subduction zone? What is the country which is sometimes referred to as a sub-continent, that crashed into Asia and formed the Himalaya mountains? What is the idea that the Earth's continents were once together in a single landmass and have since drifted apart? What is the name of the supercontinent that may have existed in the past? What is another name for a sliding boundary? What is a piece of Earth's lithosphere which floats on top of Earth's mantle? What is another name for a spreading boundary?
