Ch 10 review part B

the thin outer shell of Earth that is broken into several blocks

• asthenosphere
• terrane
• rifting
• lithosphere

boundary that forms where two plates collide

• continental drift
• transform boundary
• terrane
• convergent boundary

process by which new sea floor forms as magma rises through a rift

• paleomagnetism
• transform boundary
• sea-floor spreading
• lithosphere

hypothesis that the continents moved to their present positions

• paleomagnetism
• continental drift
• terrane
• divergent boundary

study of the alignment of magnetic minerals in rock

• paleomagnetism
• sea-floor spreading
• rifting
• divergent boundary

boundary where two plates slide past one another horizontally

• continental drift
• transform boundary
• rifting
• convergent boundary

layer of plastic rock just below the lithosphere

• terrane
• sea-floor spreading
• asthenosphere
• lithosphere

forming of cracks in weakened continental or oceanic crust

• paleomagnetism
• continental drift
• rifting
• lithosphere

boundary at which two plates move away from each other

• transform boundary
• continental drift
• convergent boundary
• divergent boundary

piece of lithosphere with a unique geologic history

• asthenosphere
• terrane
• sea-floor spreading
• divergent boundary
