ILL MARK BRAINLIEST!! 1.What is a plate boundary?

2.What are three interactions can plates have? these are the three major types of plate boundaries.

3. In general what does the theory of plate tectonics explain?

1. Plate boundaries are the edges where two of the Earth's plates meet

2. The three types of plate interacts include divergent boundaries, convergent boundaries, and transform boundaries.

3. This is the theory that the Earth's crust is separated into plates that move over the Earth's mantle. As stated, they can move in ways such as coming together, spreading apart, and interacting at boundaries all over the planet, which can cause things such as volcanos and earthquakes. Scientists created this theory as a way to explain why certain events like these are caused.
