What evidence did Alfred Wegener use to support his theory of continential drift?
Fossil discoveries
The Himalayan Mountains
Ancient maps of the world
Charts of seismic activity
What is true of tectonics plates?
They are constantly moving
Earthquakes cause them to move
They don't move for centuries at a time
There are fewer & fewer of them
What is the underlying force that drives plate tectonics?
Ocean tides
Volcanic eruptions
The rock cycle
Convention currents
What makes the plates move?
Conduction in the mantle
Convection in the mantle
Why did other scientists did no believe in Wegener’s theory?
He could not explain how the continents moved
He didn’t have evidence
His data was wrong
He didn’t use the right technology to gather data
What did Alfred Wegener call the single supercontinent that he suggested existed about 200 million years ago?
Eurasia
Pangaea
Atlantis
Gondwana
What piece of evidence for Continental Drift states that the same plant and animal fossils are found on continents separated by oceans.
Continent Shape
Fossil/Climate Evidence
Landform/Rock Evidence
Glacial Evidence
What piece of evidence for Continental Drift states that similar types and ages of rocks are found on different continents?
Continent Shape
Fossil/Climate Evidence
Landform/Rock Evidence
Glacial Evidence
What cold environment feature was evidence to support the theory that the continents used to be joined?
Same rocks were found on different continents
Glacial grooves were found on different continents
Fossilized evidence of the same organism found on different continents
Africa and South America look like puzzle pieces that fit together
According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?
Animals easily and frequently travel from Africa to South America.
Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).
Land bridges once existed that connected the continents.
South America and Africa were once connected together.

What is the significance of Harry Hess's discovery of mid-ocean ridges?
They are the deepest parts of the ocean
They are sites of new crust formation
They are the oldest parts of the ocean

What process is responsible for recycling old oceanic crust back into the mantle?
Erosion
Sea-floor spreading
Subduction
Weathering
Subduction is the process where:
new oceanic crust is formed
oceanic crust thickens due to solidification of magma
one plate is pushed down into the mantle beneath another plate
two plates push together forming a mountain

Come together
Move apart
Slide side by side
