3.Outer Core 4. Inner Core 5. The deepest zone of the mantle is much hotter than the upper zone.
Hot material rises to the top of the mantle and then cools and sinks.
This rising and sinking happens in a circular motion. When the mantle flows it moves the plates. A transverse plate boundary has two plates sliding by each other. Both plates are moving in opposite directions. A transverse boundary is like a tear in the Earth's crust.
