Convection currents form when warm air rises and cold air sinks. What causes the warm air to rise and the cold air to sink?
a deference in density
When warm air rises and cool air sinks in what is it called?
Convection Currents
What role do convection currents play as you heat a pot of water?
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
What is a convection current caused by?
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.
What forms when heated air expands and cooler air sinks below the warmer air?
Convection currents
What caused the plates to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.

What causes us to think that heat rises?
Because of convection: heat rises and cold sinks
What are Convetion Currents?
convection currents are when hot rock from deep inside the the earth rises but cooler rock near the surface sinks

Convection Currents
What causes convection currents to form in oceans?
Lighter, warm material rises while more heavier, cool material sinks. It is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
How is convection currents used in a refrigerator?
cold air sinks to the bottom of the fridge whilst the warm air rises
What causes the earth plate to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
In the Earth's mantle heat is transferred in large convection currents. Within these currents?
, hot material rises towards the surface and cooler material sinks back down towards the Earth's core. This is called mantle convection and is driven by the heat generated from the Earth's core and the heat released from radioactive decay within the mantle. The motion of these convection currents is responsible for plate tectonics and the movement of continents over time.
What role do convection currents play as you heat a pot of water?
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
