Solution to "Parts of a Volcano" Worksheet
Below is the correct labeling for each blank box in the diagram, based on the provided terms and the visual cues in the image.

####
Step-by-Step Explanation with Labels:
1.
Topmost gray cloud (above the volcano):
- This is the
ASH CLOUD – it's the large plume of ash and gas rising from the eruption.
-
✔ Label:
ASH CLOUD
2.
Opening at the top of the volcano where lava erupts:
- This is the
CRATER – the bowl-shaped depression at the summit.
-
✔ Label:
CRATER
3.
The main vertical channel through which magma travels upward:
- This is the
CONDUIT – the pipe-like structure connecting the magma chamber to the surface.
-
✔ Label:
CONDUIT
4.
Side opening on the volcano’s slope where lava flows out:
- This is the
SIDE VENT – an auxiliary vent that allows lava to escape laterally.
-
✔ Label:
SIDE VENT
5.
Lava flowing down the side of the volcano:
- This is the
LAVA FLOW – molten rock that has erupted and is moving downhill.
-
✔ Label:
LAVA FLOW
6.
Small particles of volcanic material falling from the sky:
- These are
ASH FALL – fragments of rock and glass ejected into the air during an eruption.
-
✔ Label:
ASH FALL
7.
Horizontal intrusion of magma between rock layers:
- This is a
SILL – a sheet of igneous rock formed when magma intrudes between layers of sedimentary rock.
-
✔ Label:
SILL
8.
Large underground reservoir of magma:
- This is the
MAGMA CHAMBER – a pocket beneath the volcano where magma collects before an eruption.
-
✔ Label:
MAGMA CHAMBER
9.
Vertical path from the magma chamber to the surface (same as conduit but sometimes used interchangeably):
- This is the
VENT – the opening or passage through which volcanic materials exit.
-
✔ Label:
VENT
10.
Layers of rock forming the Earth's crust surrounding the volcano:
- These are the
ROCK LAYERS OF THE EARTH'S CRUST – shown as horizontal strata beneath the volcano.
-
✔ Label:
ROCK LAYERS OF THE EARTH'S CRUST
