Let's solve the
"Volcanoes" worksheet step by step.

Part 1: Label the parts of a volcano
We are given a diagram of a volcano and a word bank:
Word Bank:
- lava
- ash
- magma
- crater
- central vent
- side vent
Now, let’s identify each labeled part in the diagram (based on standard volcano anatomy):
1.
Top center – explosive eruption with particles: This is
ash being ejected.
2.
Red molten material flowing down the slope: This is
lava.
3.
Molten rock beneath the surface: This is
magma.
4.
The large opening at the top of the volcano: This is the
crater.
5.
Vertical tube from the magma chamber to the surface: This is the
central vent.
6.
Smaller openings on the side of the volcano: These are
side vents.
So, matching the labels:
-
Top left arrow →
ash
-
Top right arrow →
lava
-
Middle left arrow (underground) →
magma
-
Bottom left arrow (tube) →
central vent
-
Side arrow (on flank) →
side vent
-
Top of volcano (opening) →
crater
>
✔ Labeling Summary:
> - Top left:
ash
> - Top right:
lava
> - Middle left:
magma
> - Bottom left:
central vent
> - Side:
side vent
> - Top opening:
crater

Part 2: Fill in the blanks
Now, let’s complete the sentences using the vocabulary.
1.
When molten rock called _______ comes from the Earth’s mantle.
→
magma
*(Magma is molten rock beneath the Earth's surface.)*
2.
When it reaches the surface of the Earth, it is then called _______.
→
lava
*(Once magma reaches the surface, it is called lava.)*
3.
Clouds of tiny particles emitted from a volcanic eruption are called _______.
→
ash
*(Volcanic ash consists of fine particles of rock and glass.)*
4.
The largest tube through which magma travels to the surface is the _______ of a volcano.
→
central vent
*(This is the main conduit for magma to reach the surface.)*
5.
Sometimes lava comes out of a smaller tube called a _______.
→
side vent
*(Side vents are secondary openings on the sides of a volcano.)*
6.
The _______ is the bowl-shaped opening at the top of a volcano.
→
crater
*(The crater forms at the summit where eruptions occur.)*
