Review Sheet for Plate Tectonics Test
_______________________________________________________
Continental Drift:
1. Who came up with theory of
continental drift? ALFRED WEGNER
2. List evidencethat the continents were
once all together.
FOSSILS
LANFORMS
CLIMATE CHANGES
SHAPE – FIT LIKE A PUZZLE
ROCK LAYERS MATCH UP
3. Why was Wegner not believed? COULD NOT EXPLAIN HOW CONTINENTS MOVED
4. Explain why fossils of the Glossopteris, a tropical plant, were discovered in
Antarctica? ANTARCTICA WAS ONCE IN A WARMER CLIMATE
Layers of the Earth:
5. Label the layers of the earth.
LITHOSPHERE
6. What happens to temperature and density
uppermost part of
CRUST
as you go from the surface of the Earth to
mantle and crust
the core? IT INCREASES
ASTHENOSPHERE
Somewhat soft part
of mantle on which
the plates float
MANTLE
7.
What layer includes the crust and the
upper most part of the mantle?
OUTER CORE
LITHOSHPERE
8. What is the uppermost most part of the
mantle that the plates float on?
ASTHENOSPHERE
INNER CORE
Plate Tectonics:
9. What is the theory of plate tectonics? THE
GEOLOGICAL THEORY THAT PIECES OF EARTH’S LITHOSPHERE ARE IN CONSTANT
SLOW MOTION
10. Where are the youngest rocks in the ocean found?
NEAR THE MID OCEAN RIDGE
11. Where are the oldest rocks in the ocean found?
FARTHEST AWAY FROM THE MID OCEAN RIDGE
12. What causes the plates to move?
CONVECTION CURRENTS IN THE ASTHENOSPHERE
13. What is the most frequent cause of major earthquakes?
SLIDING OF TECTONIC PLATES
14. Fill in the boxes below.
Boundary: : DIVERGENT
Effect: MID OCEAN RIDGE,
RIFT
Stress: TENSION
Boundary: CONVERGENT
Effect: MOUNTAINS,
TRENCHES, POSSIBLE
VOLCANOES (SUBDUCTION)
Stress: COMPRESSION
Boundary: : TRANSFORMING
Effect: EARTHQUAKES
Stress: SHEARING
15. The oceanic plate is SUBDUCTED below the continental plate in a convergent
boundary because the oceanic plate is MORE dense then the continental plate. When
this happens, the oceanic plate returns to the MANTLE.
16. Why does subduction not occur when two continental plates converge? THEY ARE
THE SAME DENSITY
17. What land feature is created during the collision of two continental crustal plates?
MOUNTAINS
18. What is formed when a river slows down and deposits sediment as it enters the sea?
A DELTA
Mapping:*take a good look at how the side and upper views compare*
1. What do contour lines represent on a topographic map? LINES OF =ELEVATION
2. What do contour lines that circle up represent? HILL OR MOUNTAIN
3. What do close together contour lines represent? STEEP SLOPE
B
A
4. What is the contour interval of
this map? 10 METERS
5. What is the elevation of point X?
30 M
6. What is the difference in
elevation between A and B? 0M
1 mile
