Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Antarctic Plate?Approximately 103 million square kilometers
2. What is the location?Underlies the continent of Antarctica and the surrounding Southern Ocean
3. What is the average movement speed?1 to 2 centimeters per year
4. Why does the Antarctic Plate move?The plate moves because forces from mid‑ocean ridges and transform faults around it push and pull it. These forces cause it to drift toward the South Pole over time.
5. What happens when the Antarctic Plate meets other plates?When it meets plates like the Nazca or South American Plate, it can push down and create deep trenches or volcanoes. These interactions also cause earthquakes along the plate’s edges.

Oceanic Lithosphere: The rigid outer layer of Earth composed of the crust and upper mantle, forming the ocean floor.
Mid-Ocean Ridge: An underwater mountain range, formed by plate tectonics where new oceanic crust is created.
Transform Fault: A fault along which the movement of the two blocks is purely horizontal.
Subduction Zone: An area where one tectonic plate slides beneath another, often leading to volcanic activity and earthquakes.
