Plate Tectonics, Types of Rock & Layers of the Earth

spreading ridge

• Processes that break down a rock to form sediments.
• the region where magma breaks through Earth's surface, continually forcing apart old rock and forming new sea floor
• A weak spot in the crust where magma has come to the surface
• made liquid by heat; melted

trench

• A deep, steep-sided canyon in the ocean floor.
• Process in which sediment is laid down in new locations.
• small, solid pieces of material that come from rocks or living things
• a valley formed by the separation of tectonic plates

Lithosphere

• The shaking that results from the movement of rock beneath Earth's surface.
• A rigid layer made up of the uppermost part of the mantle and the crust.
• A deep, steep-sided canyon in the ocean floor.
• Most geologists think that the movement of Earth's plates is caused by

Asthenosphere

• made liquid by heat; melted
• Process by which sedimentary and metamorphic rock are formed into igneous rock
• The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
• The soft layer of the mantle on which the lithosphere floats.

plate tectonics

• A plate boundary where two plates move away from each other.
• After they are deposited, sediments, such as sand, are turned into sedimentary rock when
• The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
• A type of rock that forms from an existing rock that is changed by heat and pressure

divergent boundary

• A plate boundary where two plates move away from each other.
• in tectonic plates, the site at which an oceanic plate is sliding under a continental plate.
• The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
• A plate boundary where two plates move toward each other.

plate boundary

• A plate boundary where two plates move toward each other.
• Long chains of mountains within ocean basin
• The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
• the region where two tectonic plates are in contact

Subduction

• The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
• in tectonic plates, the site at which an oceanic plate is sliding under a continental plate.
• A type of rock that forms from an existing rock that is changed by heat and pressure
• A plate boundary where two plates move away from each other.

• A plate boundary where two plates move away from each other.

transform boundary

• the region where magma breaks through Earth's surface, continually forcing apart old rock and forming new sea floor
• A plate boundary where two plates move past each other in opposite directions
• A plate boundary where two plates move away from each other.
• molten rock
