Here’s the matching of the Plate Tectonics terms from Column A with their descriptions in Column B:
-
The rise of hot less dense magma and the fall of cooler, more dense magma in the asthenosphere creates this process:
(s) Thermal Convection -
Animal Fossils that were found on several different continents, that could not have swam the ocean to get there:
(e) Lystrosaurus & Mesosaurus -
Tropical Plant fossil found in Antarctica that suggests the climate of Antarctica has changed from tropical to arctic!:
(y) Glossopteris -
The name of the process that creates new ocean crust at the Mid-Ocean Ridge:
(p) Sea Floor Spreading -
Stable interior portions of continental crust:
(a) Cratons -
Wegener's unsupported Theory that the continents were all one big landmass, and then moved apart to present day:
(v) Continental Drift Theory -
Explosive volcanic eruptions that produced dangerous amounts of lava, gas and ash:
(r) Pyroclastic flow -
The name of the Supercontinent:
(l) Pangaea -
Plate boundary that collides together:
(q) Convergent boundary -
Plate boundary that separates:
(w) Divergent boundary -
Conservative Plate boundary that doesn't create landforms, but just slides past each other:
(j) Transform boundary -
The area around the Pacific Ocean is called the Ring of Fire because oceanic crust converges with continental crust and creates one big ___________________ (string of coastal volcanoes):
(h) Volcanic arc -
Two oceanic plates collide, resulting in this string of volcanoes out in the middle of the ocean:
(u) Island arc -
A Vocab word that means "shape of the land" and describes different landforms and features:
(b) Topography -
Point underground where an Earthquake originates:
(c) Focus -
Point on the surface, directly above where the earthquake originated:
(k) Epicenter -
Theory that explains why the Continents have moved: Convection in the asthenosphere have moved the plates in the lithosphere:
(d) The Theory of Plate Tectonics -
In a convergent boundary between two crusts of different densities, the more dense crust will sink down. This is called:
(f) Subduction -
When oceanic crusts subduct under another crust, this DEEP landform in the ocean is created:
(m) Trench -
Geologist and Naval officer Harry Hess discovered the longest underwater mountain range when he was looking for enemy submarines during World War II. He named it the:
(n) Mid-Ocean Ridge -
A plate boundary that results in Earthquakes is called a:
(t) Fault -
Hawaii was made from one of these, where magma plumes upward through the middle of a plate:
(x) Hot spot -
A study of ocean floor rocks, and how the iron and nickel alignment suggest the Earth's poles have reversed several times:
(i) Paleomagnetism -
Convergent boundary of two continental crusts (with similar density) uplift to form this landform:
(o) Mountain (non-volcanic) -
Equation for a Volcano= pressure + crack in the crust+ this molten material __________ as it exits the crust:
(g) Lava
This is the complete mapping of terms from Columns A and B.
