History Of Plate Tectonics
Test Description: 8.9 A Describe the historical development that supports plate tectonics theory
Instructions: Answer all questions to get your test result.
1) A scientist found fossils of the same tropical fern in Africa, Antarctica, and Australia. What conclusion can the scientist make?
A
Birds who eat the fern also live in Africa, Antarctica, and Australia.
B
More evidence is needed.
C
The fern can live in any climate.
D
The continents have moved away from each other.
2) One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?
A
The ancient atmosphere in both places was identical.
B
Plants on both continents have similar flowers
C
Fossil remains of the same land-dwelling animal
D
The rates of weathering of rock are similar
3) Even before modern observations provided evidence that supports the Theory of Plate Tectonics, people developed theories that the continents were once joined together. Using only maps, they observed that -
A
the oceans have decreased in size throughout the history of the earth.
B
the shapes of continents appeared to allow them to fit together
C
continents with the most moderate climates were located near the Equator.
D
most of the larger land masses are in the Northern Hemisphere.
4) The most recently formed crust on Earth would be found where -
A
plates are moving sideways past each other.
B
one plate is sliding under another plate.
C
wo plates are moving apart from each other
D
two plates are pushing directly towards each other
5) Examining rocks that form on either side of the Mid-Atlantic Ridge provides evidence that supports Plate Tectonics. This is because we see evidence of plate movement in the fact that as we look at rocks farther and farther from the ridge, the rocks -
A
are made up of smaller particles.
B
become thicker and thicker
C
have higher iron content.
D
are consistently older.
6) German Scientist that developed theory of continental drift
A
Hess
B
Hertzsprung
C
Russell
D
Wegner
7) This theory explains the moving of continents, but could not answer what made the land masses move.
A
continental drift
B
sea floor speeding
C
Pangaea
D
plate tectonics
8) Which of the following is NOT evidence of continental drift theory?
A
movement of convection currents in the mantle causes the plates to move
B
Coal deposits are found in climates today where they couldn't have formed
C
Fossils of the same animal are found on separate continents
D
the shapes of the contents fit together like puzzles
9) The large super-continent that was thought to have existed was called --
A
Glossopteris
B
Pangaea
C
Mesosaurus
D
Laurasia
10) Rock clues were used to support the theory of continental drift because --
A
None of the above
B
Fossils were found in the rocks
