- Wandering Continents. If you could visit Earth as it was millions of years ago, it would look very different. The continents have not always been where they are today.
- Continental Features. The surface of the continents has changed many times because of mountain building, weathering, erosion, and build-up of sediment. Continuous, slow movement of tectonic plates also changes surface features.
- North America. North America, the third-largest continent, extends from the tiny Aleutian Islands in the northwest to the Isthmusof Panama in the south.
Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form the geographical region Oceania. In geology, a continent is defined as "one of Earth's major landmasses, including both dry land and continental shelves".
3 days ago · Islands may be classified as either continental or oceanic. Oceanic islands are those that rise to the surface from the floors of the ocean basins. Continental islands are simply unsubmerged parts of the continental shelf that are entirely surrounded by water.

Continents are often thought of as distinct landmasses and may include any islands that are part of the associated continental shelf. When multiple continents form a single contiguous land connection, the connected continents may be viewed as a single landmass.
Nov 29, 2023 · A continent is one of Earth's seven main divisions of land. From largest to smallest, the continents are: Asia, Africa, North America, South America, Ant arctica, Europe, and Australia. Usually, all nearby islands are also considered to be part of a continent. Japan, for example, is part of the continent of Asia.
Any land area surrounded entirely by water is considered an island. The exception to this definition is a land area of continental size, such as Australia, which is considered a nation-continent. But Iceland, also a nation, is much smaller and is considered an island.
