Answer to Question 1

Particles larger than 64 millimeters in diameter are called blocks when they are made of hardened lava and bombs when they are ejected as incandescent lava. Because bombs are semimolten upon ejection, they often take on a streamlined shape (like a football) as they hurtle through the air.

Answer to Question 2

A conduit is a path up which magma travels to the surface, a vent is the surface opening at the top of a conduit, and a crater is a bowl-shaped depression at the summit of a volcano.
