Tectonics
The theoretical supercontinent that existed long ago and broke up into the continents we observe today
What is Pangea
Vast mountain ranges deep below the ocean's surface
What are Mid-Ocean Ridges
This type of rock is formed from eroded and weathered rock pieces being deposited in layers
What are sedimentary rocks
Molten rock that is found underground
What is Magma
Magma that has erupted onto Earth's surface
What is Lava
The theory that a supercontinent broke up and formed the continents we observe today
What is the Theory of Continental Drift
Deep underwater troughs on the seafloor
What are Ocean Trenches
This type of rock is formed directly from lava or magma
What is Igneous Rock
These 2 forces change rocks into metamorphic rocks
What are Heat and Pressure
This plate boundary is formed when tectonic plates move toward each other
What is a convergent boundary
Evidence from these remains or traces of ancient living things that are found on different continents helped contribute to the theory above
What are fossils
The process by which new ocean crust continuously forms along mid-ocean ridges and is destroyed at ocean trenches
What is Sea-floor Spreading
This type of rock is formed from heat and pressure being applied to other forms of rock
What is Metamorphic Rock
These 2 forces break down rocks and minerals and create small pieces of rock
What are weathering and erosion
This is a break in the Earth's crust along which movement occurs
What is a fault
A theoretical ancient Giant land mass that dominated the southern hemisphere
What is Gondwana
This is the theory that continents continually grow and are consumed back into the Earth
What is the Theory of Plate Tectonics
These 2 types of rock can be changed into other types of rock through heat and pressure
What are igneous and sedimentary rocks Alex
When magma cools underground, it forms this type os igneous rock
What are intrusive igneous rocks
A vent in the Earth's crust through which molten rock flows
What is a Volcano
This scientist is credited with developing the theory of moving plates on Earth's surface in 1912
Who is Alfred Wegener
This area is created by a thinner oceanic plate moving under a thicker continental plate
What is a subduction zone
This is a natural, solid, inorganic substance with a definite chemical composition and a crystal structure
What is a Mineral
Igneous rocks are formed by these 2 processes
What are high heat and pressure
A curved line of vents in the earth through which magma flows, and forms parallel to a plate boundary
What is a Volcanic Arc
