00:00.000 --> 00:11.400
Volcanoes come in several types, each with unique features.

00:11.400 --> 00:13.560
Shield volcanoes.

00:13.560 --> 00:19.880
Shield volcanoes have broad, gentle slopes built by flowing lava that spreads out easily.

00:19.880 --> 00:25.520
The low viscosity allows the lava to spread out in thin layers, creating a shield-like

00:25.520 --> 00:27.000
shape.

00:27.000 --> 00:33.040
An example is Mauna Loa in Hawaii is one of the largest shield volcanoes in the world.

00:33.040 --> 00:38.440
Its eruptions produce lava flows that can travel many kilometers, creating new land as

00:38.440 --> 00:41.360
they cool and solidify.

00:41.360 --> 00:43.760
Dome volcanoes.

00:43.760 --> 00:49.400
Dome volcanoes have steep, rounded sides formed from thick lava that piles up close to the

00:49.400 --> 00:53.120
vent, creating a dome-shaped structure.

00:53.120 --> 01:00.320
Mount St. Helens lava dome in the USA is a prime example formed after the 1980 eruption.

01:00.320 --> 01:02.520
Composite volcanoes.

01:02.520 --> 01:08.280
Composite volcanoes or stratovolcanoes are steep and conical built from layers of lava,

01:08.280 --> 01:12.760
ash, and volcanic debris from explosive eruptions.

01:12.760 --> 01:18.600
Mount Fuji in Japan is a classic example known for its symmetrical cone shape.

01:18.600 --> 01:20.520
Cinder cone volcanoes.

01:20.520 --> 01:26.960
Cinder cone volcanoes are small, steep-sided cones created from volcanic debris like ash

01:26.960 --> 01:30.560
and cinders that fall back around the vent.

01:30.560 --> 01:37.440
Pericotine in Mexico is a famous cinder cone that appeared suddenly in a cornfield in 1943.

01:37.440 --> 01:44.320
It continued to grow and erupt for several years, creating a cone of volcanic debris.

01:44.320 --> 01:49.120
Each type tells a story of different volcanic activity and landscape formation.
