Plate Tectonics for Kids Video
The earth beneath our feet is constantly moving but it is too slow for us to notice. It moves anywhere from 1 to 6 inches in a year. These movements are caused by forces deep in the core of Earth. It is believed that earth’s outer crust is not a single piece and made up of huge fragments. These fragments are known as plate tectonics. All these plates fit together like a cracked shell. These plates make up the outer shell of Earth called lithosphere. Edges of these plates are known as boundaries or margins. Tectonic plates are around 62 miles thick.
Quick Facts: –
- The movement of plate tectonics is responsible for all different phenomena like earthquakes, mountain formation, volcanoes etc.
- There are two main types of tectonic plates which are Oceanic and Continental.
- Oceanic crust is formed at sea-floor spreading centers and Continental crust is formed through arc volcanism.
- There are total seven major plates and twelve minor plates.
- Convection cells are believed to be what keeps these plates moving.
- The entire concept of plate tectonics was developed in the 1960s from an earlier concept of continental drift.
- A German scientist, Alfred Wegener is referred to as the father of plate tectonics.
- At the edges of tectonic plate boundaries, there are cracks known as faults.
- There are three different types of plate boundaries which are convergent, divergent, and transform.
- Convergent boundaries are where plates move apart; divergent boundaries are where plates move into one another and transform boundaries are where plates move sideways to each other.
- The San Andreas Fault in California is an example of transform boundaries.
