Tectonic Plates Flashcards
Faulting
When tension and compression associated with plate movement is so great that blocks of rock fracture or break apart
Folding
Occurs where the crust is pushed up as plates collide which causes the crust to rise up in folds.
Ocean Ridge
An elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crusts forms from upwelling magma.
Ocean trench
Steep depressions in the deepest parts of the ocean and are the deepest regions on the earth.
Subduction
Movement of the edge of one tectonic plate under another
Tectonic
Pertaining to the structure or movement of earth’s crust
Isotope
atom with the same atomic number, different number of neutrons
Convection
The process where heat causes fluid (gas or liquid) to rise and bring up heat
Fossil Fuel
An energy source (fuel or gas) made from ancient plant or animal remains
Fossil Record
A piece of evidence for evolution that shows the development of organisms over time across the world
Fossil
The remains or an impression of a plant or animal that existed in a past geological age
Igneous
Rock that is formed from cooled magma or lava
Lithosphere
The section of Earth that is composed of rock
Magma
Melted rock inside of the the Earth
Metamorphic
Rock formed when igneous or sedimentary rock is put under pressure, heated, or reacts chemically
