Pangea, a supercontinent that included South America, Africa, Antarctica, India, and Australia, began to disintegrate slowly millions of years ago. Tectonic plates can move apart at increasing rates up to 20mm per year, causing violent earth movements, heat, and volcanic activity. Millions of years ago, a supercontinent now called Pangea contained what would later become […]

There are three types of plate boundaries: transform, divergent, and convergent, which cause geological phenomena such as earthquakes and mountains. Examples include the San Andreas Fault, Mid-Atlantic Ridge, and Himalayas. Tectonic plates are large, disconnected pieces of the earth’s crust, floating […]
