Science Seatwork on Volcanoes Flashcards
Most of the time, ________
boundaries are tied to
volcanic formations
Tectonic
What are all the parts of a volcano (in science slides)
Vent, Magma Chamber, Conduit, Crater, Caldera, Branch Pipe, Side Vent, Parasitic Cone, Sill
Describe the Vent of a volcano
opening or crack in the Earth’s crust caused by tectonic
movement
Describe the Magma chamber of a volcano
reservoir of magma
Describe the Conduit of a volcano
circular opening of the Earth’s crust where magma
forcibly comes out
Describe the Crater of a volcano
the summit of most volcanoes
Describe the Caldera of a volcano
wall part of the volcano that collapsed due to an
explosive eruption
Describe the Branch pipe of a volcano
created when magma rises up and passes through
other fissures
Describe the Side vent of a volcano
a vent formed from a branch pipe
Describe the Parasitic cone of a volcano
a cone on the side of a volcano formed from a
branch pipe
Describe the Sill of a volcano
hardened magma
Why do you think volcanoes develop side
vents if they already have a big main vent?
