The majority of earthquakes and volcanoes occur along _____. (This is a term, not a place.)
Plate boundaries
15
What layer is located in between the crust and the (outer) core?
The mantle
15
made up of the oceanic crust, the continental crust, and the rocky outer layer of the mantle; it is broken into plates which float on the top part of the mantle and move a few centimeters every year.
Lithosphere
15
What is the underlying force that drives plate tectonics?
Convection Currents
15
Convection currents occur in which layer of the Earth?
Mantle
15
What causes Earthquakes?
movement of the tectonic plates
15
What is the boundary that has plates sliding past each other?
Transform
15
What kind of plate boundary is around the ring of fire, causing 50% of the world's volcanoes?
