What is the name of the hotspot in the continental crust of the North American Plate?
Yellowstone Hotspot
Name a plate next to the North American plate
Pacific, Cocos, Caribbean, Juan de Fuca, Eurasian
What type of plate boundary is at the Mid Atlantic ridge
Divergent boundary
Give an example of a hotspot that has formed islands
Hawaiian hotspot
On what plate is Australia located
Australian Plate
Give an example of a convergent boundary
Peru-Chile trench, Indian-Eurasian plate, cocos-North American plate, Java trench, Kurile Trench, Aleutian trench

Where is the nazca plate located

What happens at an oceanic - continental convergent boundary
The oceanic plate gets pushed beneath the continental plate
What is a hotspot?
A hotspot is an area of unusually hot magma rising from the mantle and leads to volcanic activity
What was the name of the previous supercontinent on Earth?
Pangaea
Explain why the ocean floor has different ages at different plate boundaries
New oceanic crust is formed at divergent boundaries on the ocean surface, as new crust is formed it pushes old crust to subduction zones
The Hawaiian islands were formed by hotspots, but why are there many of them?
Hint: think of plate tectonics
The ocean floor is moving over the hotspot beneath the earths crust
True or False: we don't have any fault lines close to New York
False
