a form of energy that can travel through space. – are classified according to wavelength | Electromagnetic Waves |
the direct transfer of energy by electromagnetic waves. | Radiation |
a form of energy with wavelengths that are longer than red light. – not visible – felt as heat | Infrared Radiation |
has wavelengths shorter than violet light – cause sunburns, skin cancer and eye damage | Ultraviolet Radiation |
the total energy of motion in the molecules of a substance. | Thermal Energy |
the AVERAGE amount of energy of motion in each molecule. The higher the energy the hotter the object | Temperature |
Instrument that measures temperature | Thermometer |
the energy transferred from a hotter object to a cooler one | Heat |
the direct transfer of heat from one substance to another substance that it is TOUCHING – substances are IN CONTACT with each other | Conduction |
The transfer of heat by the movement of a FLUID (fluids are liquids or gases) | Convection |
the horizontal movement of air from an area of high pressure to an area of lower pressure. caused by differences in air pressure due to unequal heating. | wind |
instrument used to measure wind speed. | Anemometer |
winds that blow over a short distance. ** caused by unequal heating of Earth’s surface. | Local wind |
wind that blows from an ocean or lake onto the land | Sea breeze |
the flow of air from land to a body of water | Land breeze |
winds that blow steadily over a LONG distance. Movement of air between the equator and the poles | Global wind |
The curving of global winds caused by the Earth’s rotation | Coriolis effect |
