Energy and Heat Transfer

Andrew covington, Veronica Lockwood, Taylor saladyga

In what 3 ways is heat transferred to the atmosphere?

1. Conduction- the transfer of heat between two parts of a stationary system, caused by a temperature difference between the parts. Example: when you stir a hot liquid with a metal spoon, the spoons soon becomes hot2. Convection- the movement of gases or liquids in response to a nonuniform temperature distribution. Example: heat air rising, cooling, and falling.3. Radiation- transmission of energy in the forms of waves. Example: heat from the sun warming ur face and you getting sunburned.

What is the term used to refer to the direction that the sun's rays hit Earth and how does it affect the amount of energy reaching the surface?

hotter at equator; cooler at polescauses energy to spread out over wide areadifferent parts of Earth's surface absorb different amounts of energy

What does energy transfer between the Earth's surface and the atmosphere create?

The Constantly moving air creates wind and weather.

How do land and water compare in their abilities to absorb and transfer heat?

water absorbs 90%forest absorbs 85%cities absorb 95%sand absorbs 55%

Which part of Earth receives more of the sun's energy per unit area; the poles or the equator? Why?

The poles because they get the direct rays and the poles get the slanted rays which are longer.
