3. Earth’s structure
What is interesting about the shape of the continents? Name of ancient giant continent made up of all of Earth’s modern contents:
APEX page 1 – go over the puzzle with the students
APEX page 2 – simulation video
The continents appear to fit together like a puzzle because at one point, they actually were together! About 250 million years ago, the land that makes up Earth's continents was connected into one giant continent called Pangaea. Watch the video to see how Pangaea eventually broke up into the seven continents we know today. What changes do you think still happen in the Atlantic Ocean?

4. What is continental drift?
Examples of evidence of continental drift:
The idea that the continents are slowly moving is called continental drift . A German scientist named Alfred Wegener came up with this theory in 1915 when he was studying a map of Earth. He noticed that the continents seemed to fit together like pieces of a jigsaw puzzle — just as you saw on the first page of this study activity.

6. Earth’s interior Layers Thickness Description Crust 3 – 60 mi
Rocky, solid, outer most layer
Mantle
1,800 mi
Found just below the crust. Made up of extremely hot, partially melted rock that flows
Outer Core
1,400 mi
Found between the mantel and the inner core. Liquid metal that spins at a different rate than Earth, which causes Earth to act like a giant magnet.
Inner Core
800 mi
Innermost layer; made up of an extremely dense, solid metal layer.

7. Continental drift is caused by the movement of:
Tectonic Plates
Definition:
… which float on top of the:
Earth's crust is not all in one piece. It is broken up into many pieces; each part is called a tectonic plate . These plates float like giant, slow-moving rafts on top of the mantle. Sometimes they bump into one another. At other times they pull apart. But you usually can't feel their motion. That's because they move extremely slowly — about 1 inch per year.

9. Earthquakes Description: Happen more often at:
When giant plates bump into or grind past one another, stress builds up. The plates may break or snap. This leads to a sudden movement called an earthquake . When an earthquake occurs, the ground shakes. Sometimes it can shake so much that buildings collapse.
