How does fossil evidence support Wegener's hypothesis of continental drift?
Similar fossils are found along continental margins that appear to join together.
Fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils.
Similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.
All of the answers here are correct

A rift valley
An island arc
A mountain range
Plates slide past one another horizontally at _______ boundaries.
transform
divergent
convergent
subductive
This graphic depicts
An oceanic plate meeting a continental plate resulting in subduction and volcanism.
Two continental plates meeting which results in mountain formation.
A rift forming between a continental and oceanic plate.
A transform boundary that experiences many earthquakes due to strike-slip faulting.
The crust and the uppermost mantle make up the _________.
lithosphere
asthenosphere
magmetic accretion zone
tectonic zone
The Mid-Ocean Ridge is a divergent fault on the floor of the Atlantic Ocean that helps explain continental drift. Which best describes where the oldest rock is on the floor of the Atlantic Ocean?
At the very center of the Mid-Atlantic Ridge
At the far edge of the ocean plate where it meets the continents
Near northern end of the ridge around Iceland
Near thr southern end beyond the tip of Africa
What type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?
evidence from ancient climates and plants
evidence from landforms
evidence from fossils
evidence from human ancestry and DNA lineage
The Andes have been formed as a result of the __________ of the Nazca plate and the South American plate.
convergence

the driving process behind the movement of tectonic plates
the reason why there are some many volcanoes in the center of continents
the opposite of the way convection works
