Continents

Pangea

Pangea is a supercontinent that existed on Earth between 300 and 180 million years ago (Mesozoic). The word “Pangea” comes from Greek and is freely translated as “All-Earth”. Pangea was not the first supercontinent in Earth's history, but it is undoubtedly the best known of them. 1)

Alexander Island

Alexander Island (formerly Alexander I Land) is an island off the southwest coast of the Antarctic Peninsula², the largest on the continent. The island was discovered by Fabian von Bellingshausen on January 28, 1821, but until December 1940 it was thought to be part of Antarctica. It is separated from the continent by the George VI Strait, which is covered by a shelf glacier. 2)

Bentley Subglacial Trench

The Bentley Subglacial Trench is a trench beneath the surface of the Antarctic ice sheet where the rocky bed of West Antarctica is deepest below the sea surface. It is located between Ellsworth Land and Maria Byrd Land. It is the deepest part of the West Antarctic Rift, where the continent's lithosphere is thinnest, and also one of the places where the Earth's surface is lowest below sea level. 3)

Expanding ocean

The Atlantic Ocean is expanding by about 1.1 inches each year. As a result, Africa and South America, and Europe and North America are moving away from each other. 4)

Chimborazo

Chimborazo is an extinct stratovolcano located in the Andes range. It is the highest peak in Ecuador. Chimborazo is considered to be the peak furthest from the center of the Earth. This mountain was first climbed on January 4, 1880, by the English traveler and Andeanist Edward Whymper. In the Ketchua language, Chimborazo means “great snow mountain”. 5)
