Science 7 Review - Section E3 & E4

What name did Alfred Wegener give to the single land mass?

• Ponga

• Panago

• Pangaea

• Pentagon

All of the following are pieces of evidence that help explain continental drift, except for:

• folded mountains

• Glossopteris fossils

• glacial deposits

• gold deposits

The science community rejected Wegener’s idea because they believed that mountains formed when the crust wrinkled like the skin of a dried-up _________.

• apple

• pear

• grape

• orange

Mountain ranges found on the ocean floor are called:

• abysses

• pillow lava

• ridges

• trenches

Because rock is moving away from the mountain ranges found along the mid-Atlantic ridge, new rock is being formed. This sea-floor spreading indicates that the rock closest to the continents is

• harder

• softer

• older

• younger

What is involved in geothermal activity?

• water within the crust is superheated by lava

• water within the mantle is superheated by lava

• water within the crust is superheated by magma

• water within the mantle is superheated by magma

The place where tectonic plates meet is called a:

• boundary

• convergence

• divergence

• transform

A place where two tectonic plates slide past each other is called a:

• converging boundary

• diverging boundary

• subduction boundary

• transform boundary

When one tectonic plate collides with another tectonic plate, what is likely to form along the edge?

• fossils

• mountains

• river valleys

• sedimentary rocks

Over 500 million years ago Alberta was tropical and the border with British Columbia was:

• an underwater trench

• a mountain range

• a fluvial landform

• a shallow sea
