____ are volcanoes that have very steep sides
Cindercone
Volcanic mountains
Lava
. hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this:
waves that travel slower than p waves, only moves through solid rock, and moves at right angels to primary waves causing works to move up and down and side to side
Secondary waves

P wave
a longitudinal earthquake wave that travels through the interior of the earth and is usually the first conspicuous wave to be recorded by a seismograph.
