ES 7 b Plate Boundaries ES 9 Earth History

Layer E is likely this type rock:

• Sedimentary
• Metamorphic
• Igneous
• Gneiss

In which type of stress occurs as the plates move away from each other?

• convergent
• tension
• divergent
• shear

In which type of boundary do the plates come toward each other?

• convergent
• transform
• strike-slip
• divergent

This law states that the oldest rocks are found near the bottom and youngest are near the top of the sedimentary pile.

• law of relative age
• law of themodynamics
• theory of continental drift
• law of superposition

Oceanic plates separate from each other at a divergent plate boundary at the bottom of the ocean.  Magma comes up and cools between the plates, forming...

• a mid-ocean ridge
• a rift valley
• a trench

Which of the following is in the correct order from oldest Era to most recent?

• Paleozoic, Cenozoic, Mesozoic

Layers of sedimentary rock that are deposited on top of each other over time is known as:

• foliated metamorphic
• the law of equal position
• stratigraphy
• absolute age

Hot magma can rise at a subduction zone, and break through the crust in a/an...

Layer P is also known as:

• a sedimentary layer
• a foliated metmorphic rock
• a clastic rock
• an intrusion

Oceanic crust slides underneath continental crust at a convergent boundary. This is called a...
