Howdy
Here is my latest poll:

In this poll you should have answered it in the previous page and the answer is: convection. Convection is a means of energy transfer in which material heats up and becomes less dense then it originally started. Once a material is less dense it tends to rise as more dense material comes into contact with heat source and eventually will also become less dense and rise therefore creating a circular movement of material. My question to you is why does the material become less dense?
Please leave your response by clicking on comments and leave your answer to the above question. If you are one of the first to repond be sure to check back and see what others are saying and look for my posting which will give you my answer to the question.
Talk to you later.
