Volcanoes & Earthquakes

The movement of Earth's plates creates enormous forces that ...

• squeeze all rocks to the inner core

• squeeze or pull you to the epicenter

• squeeze or pull the rock in the crust

• happen every single day on mars

What is stress?

• A force that makes the earth very upset

• A force that acts on buildings/skyscrapers

• Forces that can't change the shape or volume on Earth

• A force that acts on rock to change its shape or volume

How many kinds of stress can occur in Earth's crust?

• 7

• 3

• 2

• 5

One kind of stress is tension that...

• pulls on the crust

• stretches rock so it becomes thinner in the middle

• squeezes rocks

• stretches and pushes rock further away

Compression is...

• when rocks are pushed together

• pressing two rocks together

• squeezes rock until it folds or breaks

• when no stress occurs

Shearing will..

• pushes a mass of rocks in the same direction

• push a mass of rock in two opposite directions

• causes masses of rock to slip

• cause stress to increase by five times the amount

Which of these geological features result from slowly moving over a hot spot?

• plateaus

• islands

• canyons

• deltas

At which location does the movement of tectonic plates form isolated volcanic islands, such as Hawaii?

• transform boundary

• divergent boundary

• subduction zone

• hot spot

Which geological feature most likely caused the formation of Mount St. Helens Volcano?

• converging boundaries

• diverging boundaries

• transform faults

• rift zone

Which of the following helped in the development of the theory of plate tectonics?

• measuring the depths of oceans near deep-sea trenches

• detecting magnetic striations on land once covered by glaciers

• understanding the ways organisms adapted to topographical change

• understanding rock formations of a similar age occurring on two separate continents
