CONTINENTS

A continent is one of several large landmasses on Earth. They are generally identified by convention, with seven regions commonly regarded as continents – they are (from largest in size to smallest): Asia, Africa, North America, South America, Antarctica, Europe, and Australia. The names Oceania or Australasia are sometimes used in place of Australia.

Plate tectonics is the geological process and study of the movement, collision and division of continents, earlier known as continental drift. Continental drift is the movement of the Earth's continents relative to each other. The hypothesis that continents 'drift' was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However, it was not until the development of the theory of plate tectonics in the 1960s, that a sufficient geological explanation of that movement was found.

LANDFORMS

Landforms are natural features of the landscape, natural physical features of the earth's surface, for example, valleys, plateaus, mountains, plains, hills, ...

How are Landforms Made?

Some landforms are created by the action of wind, water, and ice. This action physically changes the Earth's surface by carving and eroding land surfaces, carrying and depositing soil, sand and other debris.
 
Crustal movement and other tectonic activity inside Earth create landforms; mountains, faults, sinks, and volcanoes.
