Antarctic plate facts for kids
The Antarctic Plate is a huge piece of Earth's outer layer. It's like a giant puzzle piece that makes up the continent of Antarctica. This plate is located at the very bottom of our planet, around the South Pole. It's one of the seven main tectonic plates on Earth.

The Antarctic Plate
The Earth's surface is not one solid piece. Instead, it's broken into many large sections called tectonic plates. These plates are always moving, but very slowly. The Antarctic Plate is one of the largest of these moving pieces. It includes the land of Antarctica and the seafloor around it.
Where is the Antarctic Plate?
The Antarctic Plate is found at the very bottom of the world. It covers the entire continent of Antarctica. It also includes the ocean floor that surrounds the continent. This giant plate is bordered by several other large plates. These include the Pacific Plate, Nazca Plate, South American plate, African Plate, and Indo-Australian plate. There are also smaller plates nearby. These are the Scotia plate, South Sandwich plate, and Shetland plate. They are often considered part of the Antarctic region.
What is the Antarctic Plate Made Of?
The Antarctic Plate is made of two main types of crust. One part is the continental crust. This is the thick, lighter rock that forms the land of Antarctica itself. It also includes the continental shelf. The other part is the oceanic crust. This is thinner and denser rock. It makes up the seafloor around Antarctica.
How Does the Antarctic Plate Move?
All tectonic plates are constantly moving. The Antarctic Plate is no different. It moves at a speed of about 4 to 20 millimeters each year. This is roughly the speed your fingernails grow. This movement happens because of forces deep inside the Earth. The edges of the Antarctic Plate are surrounded by "spreading centers." These are places where new oceanic crust is being formed. This pushes the plates apart.
