Beaty CKLA Unit 5 Geology Mountains and Undersea

Rocks pushed up into huge folds by moving tectonic plates create

• fold mountains

• fault block mountains

• dome mountains

Gigantic blocks of rock moving up and down along faults create

• fold mountains

• fault block mountains

• dome mountains

Magma pushing up and cooling below the surface in the mantle makes a bulge in the crust creating

• fold mountains

• fault block mountains

• dome mountains

Mid ocean ridges on the seafloor and Wegener's theory of continental drift are explained by

• seafloor spreading

• Pangaea

Which describes the Mid Atlantic Ridge?

• a warm, bright area on the sea floor

• a long, rugged underwater moutain range

• hydrothermal vents

Which animals live around hydrothermal vents and seamounts?

• white crabs

• giant tube worms

• football sized clams

• all of these

Match the cause to its effect:

Tectonic plates move APART very slowly

• islands are formed

• mountains are formed

• seafloor spreading

Match the cause with its effect.

One tectonic plate slides UNDER another

• a trench is formed

• hydrothermal vents are formed

• islands are formed
