Layers of the Earth Crossword

The solid, plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it
Earth's crust and solid upper mantle -broken into tectonic plates
a layer of molten (liquid) iron and nickel that surrounds the inner core of Earth
a dense sphere of solid iron and nickel at the center of Earth
movement of material due to heat and density
the amount of matter in a given volume, increases with depth in the Earth
The strong, lower part of the mantle between the asthenosphere and the outer core
cooler, more dense mantle material
hot, less dense mantle material
The heat source inside Earth that causes the convection currents. (The breakdown of a elements which releases energy in the form of heat)
This is a process in which more dense materials of a planet sink to the center, while less dense materials stay on the surface.
What raised Earth's temperature during its formation
vibrations that travel through Earth carrying the energy released during an earthquake
seismic waves that compress and expand the ground like an accordion (travel through all layers of the Earth
A type of seismic wave that moves side to side. (Only travels through solids)
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane due to plates moving
the sudden occurrence of a violent discharge of steam and volcanic material due to plates moving
