When the crust is stretched by rock moving in opposite directions, compression occurs.

• True

• False

How does folding affect Earth's surface?

• Folding causes the crust to buckle, and over time, to rise up and form mountains.

• Folding causes the crust to sink.

• Folding causes the crust to bend in half.

• Folding has no effect on Earth's surface.

Why is it dangerous to live along a fault line?

• It's not dangerous at all!

• The plates are sliding past each other here and this can cause serious changes to the landscape, including a fracture in the crust.

Which type of stress occurs at convergent boundaries where plates push into each other?

• tension

• compression

• shear

Which type of stress occurs at transform boundaries where plates slide past each other?

• tension

• compression

• shear

What is syncline?

• A downfolded portion of rock layers.

• An upfolded portion of rock layers.

• A word Ms. Powell made up.

What is anticline?

• A downfolded portion of rock layers.

• An upfolded portion of rock layers.

• A word Ms. Powell made up.

In Earth Science, what is a fault?

• It is who is to blame.

• It is a fracture where pieces of earth move up, down and sideways.

• It is a break in Earth's crust where pieces don't move.

Because we rarely witness dramatic changes in the Earth, we can conclude that the Earth is not changing very much.

• True

• False

What plate boundary is illustrated?

• convergent

• divergent

• static

• transform
