Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.

Answer:
The waves travel across the ocean out of the area where the wind is blowing. Wave approaches the shore it touches bottom, and the base is slowed down, the water at the top of the wave moves faster, and causes the wave to break.
Explanation:
Gravitation between two objects increases when the distance between them decreases.
When the mass of an object increases, its gravitational pull also increases.
