continental drift
Choose all of the pieces of evidence that support the Theory of Continental Drift.
Animal and plant fossils
Fit of continents
Rock sequences
Glacial evidence
A remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in Earth’s crust.

Wegener is credited with which theory?
Continental Drift
Sea-floor Spreading
Subduction
Plate Tectonics
A technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water.
fossil
Pangaea
subduction
sonar
The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
fossil
tectonic plates
subduction
sonar
A theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle.
fossil
tectonic plates
continental drift
sonar
Which of the following is NOT a characteristic of tectonic plates?
Any plate can have part or all of an ocean basin and/or part or all of a continent.
Continents and ocean basins move on their own without the plates moving.
The plates are what are moving and carrying the continents and ocean basins with them.
The plates move through the mechanism of continental drift.
