tectonic plates
The large landmasses on Earth's crust are called continents. These are the major divisions of land on our planet.
Plate
A large segment of the earth's crust is known as a tectonic plate. These plates float on the semi-fluid asthenosphere and interact with each other at plate boundaries, where geological phenomena like earthquakes and volcanic activity occur.
Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
