Weak spot in the
crust where
magma comes to
the surface

What is magma?
Molten mixture of
rock-forming
substances, gases,
and water vapor in
the mantle

What is a batholith?
Mass of rock formed when a large body of magma
cools inside the crust

What is a Dike?
Magma that forces
itself across rock
layers and then
hardens vertically

What is lava flow?
The area covered
by lava as it
pours out of a
vent (top of
volcano)

Lava has made a river flow toward the
ocean. When it cools it will become rock.
![Page 9: Volcanoes - thehomeschooldaily.comthehomeschooldaily.com/.../2020/05/VOLCANOES.pdf · many volcanoes that rim the Pacific Ocean. ring of fire. Sakurajima is a stratovolcano on the](https://reader034.vdocuments.us/reader034/viewer/2022050403/5f810b9cdc73500716038d18/html5/thumbnails/9.jpg)
Dragon's teeth (in
Maui) is a unique
lava flow that was
influenced by high
waves as the
ancient lava flow
hit the ocean.

2 Main Types of Lava
Pahoehoe• Fast-moving,
hot lava
• Looks like solid
mass of
wrinkles,
billows, and
ropelike coils.
Aa
• Lava that is cooler and slower-
moving, not smooth

When magma or lava cools, they become igneous rock. Basalt,
obsidian, granite, and pumice are common igneous rocks.
Pumice is a light-weight igneous rock formed when lava encounters
water.

What causes volcanoes to form?
When two tectonic plates
collide, one plate slides on
top of the other while the
other is pushed down.
Pressure causes stored
magma to squeeze up
between the two plates.

Sakurajima is a stratovolcano on the island of Kyushu, Japan. It is part of the Pacific Ring of Fire.

What is a Hot Spot?
An area where magma
from deep within the
mantle melts through
the crust like a blow
torch.
![Page 17: Volcanoes - thehomeschooldaily.comthehomeschooldaily.com/.../2020/05/VOLCANOES.pdf · many volcanoes that rim the Pacific Ocean. ring of fire.

The older islands were once located above the stationary hot spot
but were carried away as the Pacific Plate drifted to the northwest .

What is an Island Arc?
A chain of volcanic islands
or mountains formed as an
oceanic tectonic plate
subducts under another
tectonic plate causing
magma to rise to the
surface.

What is the Vent?
Molten rock and
gas leave the
volcano through
an opening
Besides the main
vent at the top of the
volcano, there can
be a side vent too.

What is the Crater?
Bowl-shaped area that may form at the top of a volcano around the volcano’s central vent.

What is an ash cloud?
The cloud of ash
that forms in
the air after
some volcanic
eruptions
