Describe one benefit of volcanoes and one danger volcanoes pose?
they create new land. For example Hawaii. The eruptions can cause tsunamis
How did plate tectonics cause the formation of the hawaiian island?
The shifting of plates in the earth cause massive underwaer volcanic eruptions. Over time, the eruptions of the volcanoes cause a buildup of dried lava that eventually breached the surface of the ocean. These volcanoes are still erupting, causing the island to gradually grow.
What would happen if volcanic eruptions continued to occur on the sea floor?
There are volcanoes along the floor of the ocean that form a trench. When these volcanoes erupt, it can cause tectonic movements.
How do convergent and transform boundaries cause earthquakes?
It can cause earthquakes, volcanoes, oceanic trenches, mountains, tsunamis, and subduction.
How do volcanoes affect Hawaii?
Hawai'i was formed from volcanoes. The shape of the islands (volcanic mountains) affects the weather. Volcanic activity causes eartquakes, eruptions on the Big Island cause it to continue to grow, cause fires, close roads. Gasses from the volcanoes can cause vog (volcanic smog) and volcanoes have produced fertile soil in Hawai'i.
What is a disadvantage of volcanoes?
Volcanic eruptions can be very destructive and can threaten the lives of people living near them. Major eruptions can spread ash great distances, which can harm crops, damage machinery, and cause jet engines to fail in flight. Gasses released by large eruptions can cause climate shifts.
What type of plate boundary causes volcanic eruptions?
There are two plate boundaries that cause volcanoes. They are the divergent and convergent plate boundaries.
How a volcanoes opening affects eruptions?
Well, it could make the crater bigger. Or make it bigger. Or cause a caldera (a crater with collapsed walls)
Why are volcanoes made constructive plate boundary?
they are not as violent because the plates are sliding away from each other and it is a much smoother process
Was mount redoubt caused by an earthquake?
No. Mount Redoubt was formed by a subduction zone. While in som cases earthquakes can trigger volcanic eruptions, they do not cause volcanoes to form.
What do only the most violent volcanic eruptions feature?
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
What do underwater volcanic eruptions cause?
Underwater eruptions cause tsunamis and cause lava to form and underwater ridge.
