A Tectonic Plate is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can be very diffrent, from a few hundred kilometers to thousands of kilometers.
Two of the biggest tectonic plates are the Pacific and Antartic plates are among the largest. The Pacific tectonic plate is 103 million kilometers and is the largest. The Antarctic plate is 60 million kilometers and is the fifth largest and is estimated to move 1 centimeter per year.

What is a Teconic Plate boundary? A tectonic plate boundary is a place where tectonic plates meet.
Their are 3 types of boundaries
1.Convergent Boundaries- Boundary formed by collison of two lithospheric plates.
2.Divergent Boundaries- Boundary formed by two tectonic plates that are moving away from each other.
3.Transform Bondary- Boundary that is formed when two tectonic plates slide past each other horizontally
Scientists use a system of satellites called the Global Postioning Systmem (GPS) to measure the movement of tectonic plates. GPS systems constantly beams a signal to GPS ground stations. Tectonic plates move about 1-3 centimeters per year.
