SCIENCE 3
mountain shaped buildup formed by eruptions.
Cone
bowl-shaped opening at the volcano's top
Crater
- molten rock moving on the surface of
Lava Flow
- hot molten rock beneath the Earth
Magma
rock and ash fragments from eruptions
Pyroclastic
opening where magma and gasas escape
Vent
- thickness that controls lava's flow
Viscosity
slow wearing away of rocks and land by wind, water, or rain.
Erosion
- burst out with lava, ash or gas from a volcano..
Erupt
- breaking down of rocks into smaller picces over time.
Weathering
- watching or obscrving something carefully for changes,
like volcanic activity.
Monitoring
- Gases released from a volcano that can signal activity.

Description:
Broad, gently sloping volcanoes shaped like a warrior's shield.
SHIELD VOLCANO
Characteristics:
Built almost entirely of fluid (runny) lava; non-explosive eruptions; usually safe unless water enters the vent.
SHIELD VOLCANO
Description:
Large, steep-sided volcanoes made of alternating layers of lava flows, ash, and volcanic debris.
COMPOSITE VOLCANO (STRATOVOLCANO)
Characteristics:
Symmetrical cone shape, viscous lava that flows slowly, conduit system where magma rises.
COMPOSITE VOLCANO (STRATOVOLCANO)
Description:
The simplest type of volcano, formed from fragments of solidified lava (cinders) ejected from a single vent.
CINDER CONE VOLCANO
Characteristics:
Steep slopes, wide crater, circular or oval cone; built from loose pyroclastic fragments.
