Inside earth

Question Answer
Oceanic crust The topmost layer that includes basalt, and feldspar.
Continental crust Is the layer of granitic, sedimentary and metamorphic rock.
Lithosphere The ridged outer part of the earth, consisting of the crust and upper mantle.
Asthenosphere The upper layer of earths mantle, below the lithosphere
Mesosphere
The layer beneath the asthenosphere that is strong made of part of the mantel.
Mantle The layer of rock between the eartha??s crust and core.
Outer core The liquid layer of earths core that lies beneath the mantle and surrounds the inner core.
Inner core The solid dense center of our planet extends from the bottom of the outer core to the center of the earth, which is about 6,380 km beneath the surface.
Alfred Wagner Scientist who looked at pieces of the land on eartha??s crust.
Pangea A huge continent
Continental drift The hypothesis that states that the continents once formed a single land mass
Mid ocean ridge Are mountains chains that form where tectonic plates pull apart.
Sea flour spreading
Convection currents
The process by which new oceanic lithosphere forms.
A current fluid that results in convection
Plate boundary
Convergent boundary Is the boundary between the plate tectonics when they collide.
A tectonic boundary where two plates are moving away from each other.
Divergent boundary The boundary between techtonic plates that are moving away from each other
Transform boundary The boundary between tectonic plates that are sliding past each other horizontally.
Subduction Sideways downward movement of the edge of a plate of the eartha??s crust into the mantle beneath another plate.
Theory of plate tectonics Lithosphere is broken into plates and pieces and those plates are moving.
Volcanoes A mountain or Hill typically conical having a crater or vent through which lava,rock fragments, hot vapor, and gas are being or have been erupted from the eartha??s crust.
Earthquake A sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the eartha??s crust or volcanic action.
Hotspot A small area or region with relatively hot temperature in comparison to its surroundings.
