What does the word convection mean in science terms?
Most substances expand as they get hotter. When a gas or a liquid expands within an environment of denser and cooler gas or liquid, it will rise. What often happens to the rising material is that at some point it cools off and returns downward, so a circular current is formed, rising and falling. That is called a convection current. Convection can be defined as a heat driven motion of a fluid.
What is the energy transferred from a hotter object to a cooler one referred to?
Energy in transit from a hotter body to a cooler body is called HEAT.
What is the energy transferred from a hotter object to a cooler one is referred to as what?
heat transfer
Which way does thermal energy travel?
From the hotter to the cooler
Can energy pass to a hotter subject to a cooler object?
There's no scientific reason why heat energy can't flow from a cooler objectto a warmer object, making the cool one cooler and the warm one warmer.But the probability of it is so small that the statement "That never happens." isused in the field of Thermodynamics as if the statement were a law of nature.
Do plates become more dense or less dense when they become cooler?
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
Is the sounthern cooler or hotter?
hotter
What actions are going on in the mantle?
Convection currents. It's when hotter material floats to the top, and the cooler and denser material goes and gets hot again.
What happens to the temperature and the density of the the material?
When the material gets closer to the core it gets hotter and more dense.
What are convection current and how are they formed?
Convection currents in the earth originate in the mantle. The liquid moves in a circle pattern as the hotter magma rises and the cooler magma falls. This can also be observed in any fluid material, gases or liquids.
Why will the sun get hotter and hotter?
It wont, as the sun expands over time, the sun will become cooler and cooler.
What happens to the temperature and density of the material in the earth?
When the material gets closer to the core it gets hotter and more dense.

Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
Heat is transferred from?
hotter to cooler areas?
