Rocks and Minerals
Rock
A Solid combination of minerals
Pangea
The name of the supercontinent
Volcano
A mountain through which lava, rock, hot viper, and gas erupt from the earth's crust.
Crust
The thin rocky outer layer of the earth
Geology
The study of planet earth including its composition and structure.
Minerals
A natural inorganic solid ( no carbon atoms) with a crystal-like structure and chemical characteristics
Plate Tectonics
The modern accepted theory is that giant plate pieces of the earth's Lithosphere move about slowly on top of the asthenosphere.
Earthquake
A shifting movement in the lithosphere tectonic plates that realise energy
Core
The metal center of the earth
red + Blue=
Purple
Igneous Rock
A rock that forms magma and 02 decrease
Mid-Ocean Ridge
A Chain of underwater mountains in all of earth's oceans with a deep volcano valley running through the central crest.
Fault
The line between two colliding plates
Mantle
A inner thick layers of hot solid rock
Density
How compact the atom are
Sedimentary Rock
A rock forms over time as sediment gets squeezed together via erosion, deposition, compaction, and cementation.
Sea-Flooring Spreading
The process by which new oceanic crust is made at mid-ocean ridges and older oceanic crust moves away.
Epic center
The location of the earthquake on earth surface
Outer Core
The center of the earth made up of liquid metal
Rock formed on the surface of earths crust
Metamorphic Rock
A rock is formed by changes in temperature pressure chemical reactions deep underground.
Subduction of Oceanic Plates
When old oceanic plates sink beneath the continental plates forming a trench and become destroyed by the mantle forming new magma.
Focus
The location of the earthquake underground
Lithosphere
