Tectonic Plates
Inner Core: A ball of hot, solid meatls. Outer Core: A layer of liquid meatls that surrounds the innner core Mantle: Earths Thickest layer, measuring nearly 2,900 kilomenters.
Lithosphere: the layer made up of the crust and the rigid rock of the upper mantle. asthenosphere: a layer of hot, soft rock in the upper mantle.
Tectonic Plates: when the lithosphere is broken down iinto many large and small slabs.
Continenet's change position
Continental Drift: the hypothesis that Earth's continents move on Earth;'s surface Pangea: When all the continents are conjoined
Mid-ocean ridges: huge underwater maountain ranges. Convection: energy transfers by movement of a material. Covetion Current: a motion that transfers heatenergy in a material.
Theory of plate tectonics: a theory statibng that eartjs lithosphere is made up of of huge plates that move around and change size over time
Earth's Layers
Boundaries
Divergent Boundary: occurs were plates move apart Convergent Boundary: occurs werer plates push togethar Transform boundary: Occurs were plates scrape past each other
Types of Plates
Subduction: when one plate sinks beneath another Continenet-continenet collision: were 2 plates carrying continental crust push togethar oceanic-oceanic subductuin: were one oce plate with oceanic crust sinks below a nother. oceanic-continenetal subduction: were oceanic crust sinks below continenetal crust
