molten rock that has reached above Earth's surface

• hot spot

NGSS.MS-ESS3-2

one of the ingredients that determine whether a volcanic eruption will be explosive or not

• silica

• tephra

• lava

• pyroclastic flow

volcanoes occur here; these locations are NOT found at plate boundaries but instead in the middle of plate areas where there is very hot magma

• vent

• pyroclastic flow

• andesitic

• hot spot

destructive mass of very hot volcanic ash and debris flowing down slope at great speed

• pyroclastic flow

• tephra

• granitic

• magma
