Now that you know about plate tectonics, you should learn about boundaries. As you already learned, the crust is divided into many different plates, and the plates move around on the mantel. Sometimes, the mantle is more solid and sometimes it is more watery, the plates move faster when the riding on the more watery mantle and slower when on more solid mantle. The plates move and when plates interact with each other, they form boundaries. There are three types of zones, one of them is the spreading zone, another is fault zone, and the last is converging zone. The spreading zone is mostly found under the sea. These zones are formed when the plates move away from each other. The opening constantly open up and opening into the mantle. When the mantel hardens, new earth is formed, the plates then keep moving apart and keeps on creating new earth.
Another type of boundary is a fault zone.
A fault zone is when two plates slide past each other. No new earth is formed, no earth is lost. Sometimes earthquakes occur at these fault zones. The third type of zone is the converging zone.
A converging zone is formed when two plates move together. Sometimes, when two plates meet, the denser plate slides down and join the mantle, creating earthquakes and sometimes even volcanoes, but when the plates crash head on, mountains form. That is what happens at the zones.
