Shallow earthquakes are common where plates separate along what boundary.
What is a divergent boundary?
500
Scientist use wave motion, wave speed, and type of material the wave travels through to determine.
What is classifying a seismic wave?
500

The denser plate sinks under the more buoyant plate in the process.

What is subduction?
500

Gas in the atmosphere that absorbs and reradiate  thermal energy from the sun.

What is greenhouse gases?
500
Volcanoes that are not associated with plate boundaries.
What is a hotspot?
