Explain the relationship between plate tectonics, earthquakes and volcanoes. -Explain how Plate Tectonics create earthquakes.When the plates push together at convergent boundaries the compression forces create earthquakes. When the plates pull apart at divergent boundaries the tension forces can create earthquakes. When the plates slide past each other at transform boundaries they also catch on each other creating earthquakes.

Explain the relationship between plate tectonics, earthquakes and volcanoes.

-Explain how Plate Tectonics create volcanoes.When a plate boundary creates a subduction zone at a convergent plate boundary, the compression forces create stress fractures in the other plate. As the plate goes into the mantle, the magma is forced up through the fractures/cracks to create volcanoes. At a divergent plate boundary, the plates are pulled apart leaving a void that is filled by magma that may create volcanoes.

Explain the relationship between plate tectonics, earthquakes and volcanoes.

-Explain how earthquakes and volcanoes are related to each other, other than they are both caused by Plate Tectonics.Earthquakes and volcanoes are both formed at plate boundaries by the interaction of the plates. They are usually found in the same areas. Earthquakes often are a precursor to volcanic activity.

Explain at least three ways in which earthquake movements and/or volcanic activity may impact society. You need at least one example for each.

This is a list not an explanation. -Damage to structures: freeways, bridges, buildings, homes, water and gas lines, electrical lines, etc.

-Social and community challenges: lack of food, water, shelter, -job losses, higher prices, delayed flights, etc.

-Tsunamis: mass flooding and possible deaths.

Explain what role basaltic magma has in the formation of the Hawiian Islands. How does the basaltic magma influence the type of volcano the Hawiian Islands are and their shape?

The basaltic magma that created the Hawaiian Islands in being pushed up through a hotspot vent at the bottom of the Pacific Ocean. The basaltic magma is very fluid due to its low silica content. Because it is so fluid, it has a tendency to create “gentle” eruptions that allow the lava to flow out instead of blowing-up violently. Therefore, the resulting shield volcanoes created are very tall and wide because the lava can flow for great distances before it cools.
