Most tectonic playes have both oceanic and continental crust. How are oceanic and continental crust different?
Oceanic crust is thinner and denser than continental crust

What is the difference between Lava and Magma?
Magma under earth's surface, Lava on earth's surface

What is the Focus and what is the epicenter
Focus is the location of an earthquake along the fault Epicenter is where exactly on earth's surface

Two types of seismic waves are body and surface. What is the main difference between body waves and surface waves.
Body waves travel from focus, surface waves travel from surface (epicenter)

Pyroclastic flows are the most dangerous type of volcanic eruption. Extremely hot gases and fragment of rock travel at speeds over 100 km per hour. Which type of volcano is made mostly of pyroclastic materials?
Cinder Cone
400
What causes earthquakes to happen?
Rocks along an underground fault move suddenly and release energy.

Why do tectonic plates sink due to convection?
The hotter the lava gets it acts as quick sand resulting the plate to sink
