Which two plates are interacting off the northwest coast of North America and what type of plate boundary do they create?
Juan de Fuca Plate and North American Plate collide in a convergent subduction boundary.
200
What is the equation for density?
Density = Mass / Volume

How do density, temperature, and pressure change as you go deeper into the Earth?
They all increase

Use plate tectonics to explain why the Earth does not get larger over time.
New crust is created at divergent boundaries at the same rate that old crust is destroyed at convergent boundaries.
