_____ used to project sound waves to detect depths and sizes of objects. This allowed us to finally map the ocean floor!
SONAR TECHNOLOGY
Mesosaurus , Cygnognathus, Lystrosaurus, & Glossopteris found in places were found on separate continents and nowhere else. (Fossil, Climate, Mountain, Geometric)
FOSSIL
New crust can form at places in the ocean where two plates pull apart from each other.
DIVERGENT
Meteorologist who believed that the Earth was once a supercontinent called Pangaea. As time progressed these continents, moved and drifted apart.
ALFRED WEGNER

GEOMETRIC
______ is sliding past each other
TRANSFORMING
A theory stating that the Earth's continents have been joined together and have moved away from each other at different times in the Earth's history
CONTINENTAL DRIFT

17
______ moves plates by pulling them down at subduction zones
GRAVITY
_____ moves the plates as rising magma pushes at the mid-ocean ridge.
PRESSURE
These plates move sideways past each other and create a break in the Earth’s crust called a fault.

SEAFLOOR SPREADING - MIDOCEAN RIDGE
TRANSFORM BOUNDARIES FORM WHAT?
EARTHQUAKES
He came up with the idea that the continents move because the ocean floor is getting wider.
