Tectonic plates are the name given to the different sections of the Earth’s crust. 
You can think of the earth like an egg, and the earth’s crust like the egg shell - a thin, rigid outer layer. 
The crust is made of hard rock, however the layer underneath (the mantle) is made of melted, or molten rock. This molten rock under the earth’s crust is constantly moving due to a process called convection currents, and this movement drags the crust above it. As the thin, hard rock of the crust is pulled around by the moving, molten mantle, it breaks apart, and crashes together. 
These broken sections of crust are your tectonic plates. 

The crust and the mantle of the earth are made up of rocks called tectonic plates. They usually fit together like a jigsaw. They are always moving a little which over a long period of time makes continents shift. This is called continental drift. Things like earthquakes happen when plate tectonics shake due to build up of pressure in the earth's crust. Hope that helps.

Tectonic plates, also known as lithospheric plates, are massive bodies of rocks. The lithosphere is made up of the Earths crust and upper mantle.

They move in 3 types of ways. 
1. Divergent: moving apart, forming rifts both oceanic and continental. 
2. Convergent: moving together, forming volcanoes and mountain ranges. 
3. Transform: rubbing side by side, forming fault valleys or undersea canyons. 

Earthquakes can occur along any of the 3 types of boundaries. 

There are 7 major plates and around 15 smaller ones all moving a few centimetres per year!





Geography

What are tectonic plates?

Headlands are coastal landforms created due to erosion.
Headlands are formed on a coastline where you have different layers of hard and soft rock next to each other, perpendicular to the sea. 
The headlands are made of hard, resistant rock. Next to the headland will be a band of soft, weaker rock. 
As the sea smashes against the coastline, the soft rock gets eroded (broken down) more quickly, and will retreat. The hard rock still gets eroded, but much, much more slowly.
As a result, the softer rock on either side of the hard rock gets eroded back, inland. The harder rock is now sticking out into the sea, creating a landform called a headland.
Hope this helps!

Hi!

A headland is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory*. A headland of considerable size often is called a cape.

*If you're not sure what a promontory is: A promontory is a raised mass of land that projects into a lowland or a body of water (in which case it is a peninsula).
