Changing Earth Ch. 1 Review Who am I?
I’m an area of volcanic activity that develops above rising plumes of magma. Hot spot
I’m the huge underwater mountain ranges that are present in every ocean and circle the earth. mid-ocean ridges
I’m one plate sinking beneath another. Subduction
I state that Earth’s lithosphere is broken into huge, moving slabs of rock driven by motions in the mantle. Theory of plate tectonics
I’m the name that Alfred Wegener gave to the huge supercontinent that he proposed had once existed. Pangaea
I’m the place where older crust is destroyed because two plates converge, or push together Convergent boundary
I occur where two plates move past each other in opposite directions. Transform boundary
I’m the hypothesis that proposed that Earth’s continents were once joined in a single landmass and then gradually moved apart Continental drift
I’m the layer of hotter, softer rock in the upper mantle. Asthenosphere
I’m a plate with oceanic crust sinking under a plate with continental crust. Oceanic -continental subduction
I’m the layer of liquid metals that surrounds the inner core. Outer core
I’m the motion created when heated material continually rises, cools, and sinks. Convection current
I’m the thin layer of rock that surrounds the Earth. Crust
I’m the gap that forms as tectonic plates move apart Rift valley
I am the layer at the center of the Earth. Inner core
I am the three pieces of evidence that proved Wegener’s Continental Drift theory to be correct. Fossils, climate and geography
I am the main driving force of plate tectonics. convection in the astenosphere
I am the part of the Earth that makes up a tectonic plate crust and upper most mantle
I am a boundary that is also known as a spreading center. Divergent boundary
I am the pattern formed by magnetic minerals at a mid-ocean ridge. Same on either side of the ridge
I was formed after a continental- continental collision of the African and European plates. The Alps
Hint: How do the studies of the ocean floor- and everything that is happening there- help explain the theory of plate tectonics?

Plate Tectonics CHAPTER the BIG idea The movement of tectonic plates causes geologic changes on Earth. Earth has several layers. 1.1 Continents change.
Inner core – hot, solid iron and nickel Outer core – hot, molten iron and nickel Mantle – hot rock Crust – solid outer layer of the Earth 1.
1.1 Earth has several Layers. Denser material sinks Less dense material rises to the top.
