epicenter- Point on earth’s surface directly above the focus of the earth quake

plate- Slab of earth’s lithosphere that can move around on the planet’s surface

Seismometer- Equipment that measures seismic waves and other ground motions

# data[].attributes.body
Convection cell- Hot material rises and cool material sinks in a circular pattern

Seafloor spreading- Mechanism for moving continents. The formation of new seafloor at spreading ridges pushes the lithosphere plates on earth’s surface

Plates boundary- Location at which two plates come together

In the cold war, when they were testing atomic bombs, they used seismometers which measured seismic waves and other ground motions. Such as earthquakes. The seismometer put epicenters where the earthquakes were. They outlined the tectonic plates. This is because the plates move. The plates boundaries move away from each other, towards each other, and next to each other. Not only can this movement create earthquakes, it can also create mountain ranges, volcanoes and other features of earth's surface. The movement of earth's plates is caused by convection in the mantle, seafloor spreading is caused by the same thing.
