2The Earth is Made of 5 Physical Parts LithosphereAsthenosphereMesosphereOuter CoreInner Core
3Lithosphere The cool, outermost layer of the earth. The Lithosphere consists of:CrustRigid, uppermost part of the mantle.The Lithosphere is divided into 2 huge pieces called Tectonic Plates.
4AsthenosphereThe solid, soft layer of the mantle below the lithosphere.The Asthenosphere is made up of mantle rock that flows very slowly, allowing the tectonic plates to move on top of it.
5Mesosphere Middle Sphere The Mesosphere is the solid lower part of the mantle below the asthenoshpere.
6Outer & Inner Core Outer Core Inner Core The outer shell of the Earth’s coreIt is made of liquid iron and nickel.Inner CoreA sphere of solid iron and nickel.
7Plate TectonicsPlate Tectonics is the theory that the lithosphere is divided into tectonic plates that move around on top of the Asthenosphere.There are 3 types of Tectonic Plate Boundaries:ConvergentDivergentTransform
8Convergent BoundaryThe boundary that is created when two tectonic plates collide.There are 3 types of Convergent Boundaries:Continental/ContinentalContinental/OceanicOceanic/Oceanic
9Continental/Continental When two tectonic plates with continental crust collide, they buckle and thicken, pushing the continental crust upward.
10Continental/OceanicWhen a tectonic plate with continental crust crashes into a tectonic plate with oceanic crust, the oceanic plate slides under the continental plate.The region where oceanic lithosphere sinks into Asthenosphere is called a subduction zone.
11Oceanic/OceanicWhen two oceanic plates collide, one of the oceanic plates is subducted, or sinks, under the other.
12Divergent BoundaryThe boundary that is created when two tectonic plates separate.Also called rift zones.As the two tectonic plates move apart, magma rises to fill the gap.At a mid-ocean ridge, the rising magma cools to form new oceanic lithosphere.
13Transform BoundaryThe boundary that is created when two tectonic plates slide past each other horizontally.As the two tectonic plates slide past one another, they are not smooth, they grind and jerk as they slide, producing earthquakes.
