warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
The type of current that creates warmer climates along coastal areas is called (Warm-Water)
convection current
When a weather phenomenon called El Nino happens, the eastern Pacific is warmer than normal.
It gets warmer, has a lesser volume. It is called melting.
A convection current, however, this can also occur with gases.
On the tip of Cape Hatteras. It actually looks as if two oceans are colliding.
A convection current in air will have warmer air near to the heat source and this will rise. Then it gradually loses heat to the surroundings and sinks again, so there is warmer air in parts of the current and cooler air in other parts.
teeth
The Earth is warmer than in previous natural cycles.
when the day gets warmer dew melts
a surface current is warmer becasuse it isn't near the bottom of the ocean its near the top so it gets more heat
