4
Clouds of hot ash and chunks of molten rock,
shooting out of a vent at high speed.
5
Characterized by calm rivers of red-hot lava.
6
A hole in the Earths crust through which magma
rises to the surface.
7
The area deep beneath the Earths surface where
magma collects.
8
During the 1980 eruption of this volcano, 600 km2
of forest was flattened and scorched.
9
The area surrounding the Pacific Plate which
contains almost 75 of the worlds active
volcanoes.
10
The newest Hawaiian island, still covered by
water.
11
The location of Mount Rainier.
12
Where volcanoes are most likely to form.
13
Places within tectonic plates that are directly
over columns of rising magma.
14
These explosions usually pose a greater threat
to property than to human life.
15
This can smother crops, causing food shortages
and loss of livestock.
16
Many of these may occur as magma shifts and
rises within a volcano.
17
This can cause sunlight to be blocked,
resulting in a drop in global temperatures.
18
This volcanic mud is created when hot volcanic
ash mixes with water.
19
This type of volcano is made of only pyroclastic
material.
20
This type of volcano has alternating layers of
lava and tephra.
21
This type of volcano has gently sloped sides
and a wide base.
22
These landforms are created when empty magma
chambers collapse.
23
These are created when lava flows over a large
area of land after it escapes from a crack in the
Earths crust.
24
This type of lava is runny and hardens with
wrinkles that look like rope.
25
This element causes magma to thicken, and
sometimes block a volcanos vent.
26
Magma will liquify when this decreases.
27
This lowers the melting temperature of rock.
28
This causes hot magma rises to the surface of the
Earth.
