How is thermal energy produced and dilivered to you through a flat iron?
An electric iron has a heating element that offers electrical resistance. The resistance causes friction to occur in the electrons and causes a heating effect.
How is wind collected or generated?
The Generation from the result of the uneven heating on the Earth's surface.
Why is an electric skillet called oil core?
Oil core electric skillets are top of the line! the heating element is encased below the surface and submerged in oil to provide even heating across the entire pan surface. Ever see that burn ring on the surface of a old standard electric skillet? Very uneven cooking.
What is the link between the uneven heating of the earth's surface and air movement?

Surface currents are caused by friction between which two elements?
the ocean surface and wind
Are the elements air and wind 2 separate elements?
Air and wind are not elements. There are not located on the Periodic table so they can not be considered elements. Wind is caused by uneven heating on the earths surface, so wind is just another form of air.
Is the lid for the Precise Heat Electric Skillet made of glass?
Yes the Precise Heat Electric Skillets lid is made of glass. It also features a non stick cooking surface and a great heating element.
What season is it when the sun is heating earths surface the most?
It is summer when the sun is heating earths surface the most.
When are weather systems set in motion?
by the unequal heating of the earth's surface. by the unequal heating of the earth's surface.
