types of volcanoes
Volcanoes that are common along divergent plate boundaries at oceanic hot spots. They are large with gentle slopes of basaltic lavas.
What is Shield Volcanoes?
When tiny particles of pulverized volcanic rock and glass shoot high into the atmosphere.
What is..Volcanic Ash Eruptions?
Vibrations in the ground that result from movement along breaks in Earth's Lithosphere.
What is Earthquakes?
Volcanoes that are large, steep-sided, and result from explosive eruptions of andesitic and rhyolitic lava and ash along convergent plate boundaries.
What is Composite Volcanoes?
When magma has low viscosity , gas can escape easily, when the magma erupts at the surface and it forms lava flows. These eruptions are (relatively!) gentle.
What is an Effusive eruption?
Breaks in the Lithosphere
What is Faults?
What is Cinder cones?
When volcanoes spew lava powerfully.
What is an Explosive Eruption?
large, rigid sections of the Earth's lithosphere (crust and upper mantle) that move and interact, causing earthquakes, volcanoes, and mountain ranges
What is Tectonic Plate?
Volcanoes that are not associated with plate boundaries.
When volcanoes erupt mainly Water Vapor, Carbon Dioxide, Sulfur Dioxide, Hydrogen Sulfide, and Hydrogen Chloride.
What is Gas Eruption?
Large, basin-like depressions formed after a volcano collapses following a massive eruption, often resulting in a large crater or depression.
Fast-moving, hot, and destructive current of gas and volcanic debris that flows down the slopes of a volcano, often at speeds exceeding 100 km/h.
What is Pyroclastic flow?
