Plate Tectonics

When comparing the Earth's crust to the core, the core is.....

• less dense, cooler, and has more iron
• less dense, hotter and less iron
• more dense, hotter, more iron
• more dense, cooler, less iron

When two continental plates collide what may form?

• mountain range
• rift valley
• volcanic islands
• deep ocean trench

How were these mountains most likely formed?

• Transform boundary
• Divergent boundary
• convergence of two continental plates
• convergence of an oceanic and a continental plate

What land form usually forms above a hot spot?

• barrier island
• volcanic island
• peninsula
• continent

What would explain the formation of this trench?

• Sea Floor Spreading
• Weathering & Erosion
• Convergence of ocean plates
• Transform boundary faulting

What type of boundary is the San Andreas Fault?

• Transform
• Divergent
• Convergent
• Convergent/Transform

What is pangaea?

• all the continents
• only Europe and Asia
• only South America & North America
• North & South Pole

The theory of plate tectonics is a result of....

• knowing that Pangaea was a super continent
• why the continents have always been in the same place
• finding older rocks near continents and younger rocks near the center of the oceans
• similar fossils being found on all continents

What tectonic plate fault occurred in the picture?

• Divergent
• Transform
• Convergent

If the same type of mountain evidence was found in both South America and Africa, which statement would be FALSE?

• The continents were once joined together
• The evidence was found in the same hemisphere
• Some of the same mountains were once on both continents
• Every mountain range has the same rocks
