Scale now used to measure larger earthquakes
Moment Magnitude Scale
Who first presented the idea of the supercontinent Pangaea
Alfred Wegener
The term for plants that naturally grow in areas without any human interference
natural vegetation
Which plate boundary creates the most powerful earthquakes?
convergent boundary
The Appalachian Mountains are much lower and more rounded than the Rockies because of this long-term natural process
Erosion

Pacific Ocean
The age of amphibians and fish

natural vegetation is determined by which 2 factors
climate and soil
The imaginary line that divides the Earth into the Northern and Southern Hemispheres is called this
the equator
4 ways eroded material is transported and deposited
Wind, Water, Ice (Glaciers), Gravity
When two plates slide past each other horizontally, they form this type of boundary — like the San Andreas Fault in California
Transform Boundary
Era pangaea formed
Paleozoic
the boundary between the tundra and the taiga/boreal forest region
the tree line
The deepest point on Earth’s surface is located in this oceanic trench (at a convergent boundary)
Marianas Trench
Two environmental impacts of glacial retreat
After a major earthquake, smaller tremors that follow are called this
Aftershocks
What province AND provincial park in Canada were the most significant dinosaur fossils found at (now UNSECO protected)
Dinosaur Provincial Park, Alberta
This phenomenon occurs when mountains block moist air, causing one side to be wet and the other side dry, creating deserts or dry grasslands
