4 this is created when volcanic ash is propelled into the atmosphere during an eruption.
6 a large elongated depression with steep walls formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems
9 a linear feature that exists between two tectonic plates that are moving away from each other.
12 an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide
13 an opening exposed on the earth's surface where volcanic material is emitted.
14 a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash
15 a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading.
16 a boundary where two tectonic plates collide and, because of differences in density, one dives beneath the other.
18 hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this.
19 How many major plates are there?
20 hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling
1 a circular depression in the ground caused by volcanic activity. It is typically a basin, circular in form within which occurs a vent (or vents) from which magma erupts as gases, lava, etc.
2 a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle
3 a large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill.
5 a channel for conveying lava up and out of the volcano
7 the powdery residue left after volcano's explosion
8 a long, narrow ditch.
10 mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust
11 a mound of viscous lava that has been extruded from a volcanic vent.
17 where two plates slide past one another
