The lithosphere: Rigid outer shell of the earth. Composed of crust and upper most part of the earths mantle.
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, THIS happens...
eruption.
What is the range of the fuji scale?
F0 - F5
What is the relationship between volcanoes and earthquakes?
The earthquake activity of numerous volcanoes is closely monitored to provide warning signs of an imminent eruption. Large volcanic eruptions, especially the explosive type, can release huge amounts of energy that can be recorded by seismographs even far from the source.
- Both linked to plate tectonics.
In an eruption, ___________ shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.
gases and rock
