When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
What will rise and what will sink?
a stone will sink and a feather would rise
How does convection in the earth's mantle cause magma to rise?
it works like air and a radiator the heated air rises and cools then falls and the process is repeated again and again
Why rock is heated forms magma?
The rock melts, just like most other solids do when heated. Magma is to rock as water is to ice.
In volcanic areas groundwater heated by magma is a source of what?
In volcanic areas the heated water is a source of escape for the volcanic gases. Water heated by magma gets very hot and needs to have a place to go or the ground will explode.
Do molecules rise or sink after they are heated?
Rise
Does heated air rise or sink?
rise
When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
Why does magma rise when it is nearer to the core?
Water that is heated expands and rises to the surface of the tray. Similarly, the magma expands and rises to the surface of the tray. Similarly, the magma nearer the core expands and rises to top of the mantle.
Why does magma rise toward the crust and not sink into the mantle?
By being less dense than, so slightly buoyant in, the surrounding rock.
Will a liquid sink when its hotter than the liquid around it?
No, usually it will rise, since the density of most liquids will decrease as it is heated up.
What is it called when magma or steam that has been heated by magma?
lava!
What will rise and what will sink?
a stone will sink and a feather would rise
How is convection current related to earth's mantle?
It allows for the cycling of magma that is cooler than the rest to sink further down under where it's warmer and the warmer magma to rise up further because it is less dense and get cooler where the cooler magma used to be.
Why might molten rock rise and sink beneath the earths surface?
changes in buoyancy due to changes in density differences between the magma and surrounding rock.
Does atoms and molecules of gases and liquids are heated they sink?
after atoms and molecules of gases and liquids are heated, they sink?
What is the water for geothermal power plants heated by?
Magma-heated rock.
