1
How could the fossils of an ancient living thing be on different continents?
Land masses must have been connected in the past.
Meteor impact threw them across the ocean.
Glacier ice lowered the ocean for creatures to walk across.
By flying or floating across oceans.
2
Evidence of ancient plant and animal life found on different continents is what type of proof?
Fossil Evidence
Age of Rock Evidence
Mountain Evidence
Sea Floor Spreading
3
Where should someone look to find the oldest rock on the planet?
At divergent boundaries.
At mid ocean ridges.
At rift valleys
Where plates subduct.

7
What fact could Alfred Wegener not provide evidence, leading to disbelief in his theory?
Fossil Correlation
Continental Shape
Sea Floor Spreading
Strong enough force to move plates.
8
What is occurring at mid ocean ridges?
Tectonic plates are slowly pulling apart.
Tropical plants are forming there.
Two plates are colliding, causing subduction.
Large amounts of water are being added to magma there.
9
Where is new rock constantly being formed near the surface?
Ocean trenches
Strike slip fault lines.
Colliding continental plates.
Mid ocean ridges.
10
How do mountain ranges help prove plate tectonic movement?
Measuring how tall they are proves motion.
Different ages and rock types prove it is moving around.
Same age & rock type mountains line up on diff continents.
Measuring how short they are proves motion.
11

Earthquake
Rift Valley
Tsunami
Ocean Trench

Mountains
Rift Valley
Trench
Subduction Zone
