lava flow

A

flows out the volcano onto the surface

17
Q

AA

A

blocky basalt with ragged clinkery surface

18
Q

Strata volcano

A

large steep sided cone over a subduction zone

  • made of andesite
  • lava runs fast
19
Q

Caldera forming eruptions

A

rhyolite volcanoes

-very devastating

20
Q

Pyroclastic flow

A

hot volcanic ash and steam that pour down because it is to dense to rise

21
Q

Volcanic weather

A

rain falling during an eruption because of the ash
