What happens to warmer in a convection current?
warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
What direction do convection currents move?
Warmer material in a convection current rises upwards.
Which way round does convectional current flow?
A convection current flows in a circular pattern, with warmer material rising and cooler material sinking (due to density differences). It should not be used with conveNtional current in electricty.
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Is there warmer air in a convection current?
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.
What is convection in liquid?
The convection is a current caused by warmer liquid rising and cooler liquid sinking.
A circular flow of warmer fluid and colder fluid is called?
convection current
What is the circulating current of warmer material?
teeth
What way does air move in a convection current?
Warmer air rises and as it cools will descend.
Type of current that creates warmer climates along a coastal area?
The type of current that creates warmer climates along coastal areas is called (Warm-Water)
A convection current that blows wind from the cooler sea toward warmer land during the day?
sea breeze
Why cant convection happen in solids?
Convection is the transfer of heat via the movement of warmer material nearest a source of heat toward colder regions, while colder material moves toward the heat source. Usually, the warmer material moves upward from the heat source (since "heat rises") and then is pushed outward toward colder regions, setting up a circulating current that pushes the colder material sinks downward and toward the heat source. Unlike conduction (where heat is transferred by direct contact with the heat source) or radiation (where the heat source sends out waves of heat), convection requires a circulating "current" -- where material moves or flows within a fluid, such as a liquid or gas. This flow is not possible within a solid -- where the material inside cannot move from place to place. Convection cannot occur in a vacuum, either, since there is no material to flow from one place to another.
