Wind: the horizontal movement of air –Useful in many ways: 1. moderates surface temperatures 2. distributes moisture 3. cleanses the atmosphere -Wind is constantly blowing across Earth’s surface! –What sets the air into motion? *Differences in air pressure! -Air wants to flow from an area of high-pressure to an area of low-pressure. *For example: When…
Air Pressure: the force of air molecules exerted on a given area; the weight of the atmosphere as it pushes down upon Earth’s surface -Exerted in all directions because air molecules move in all directions. –Why aren’t we crushed by its weight? Because as the air is pushing in all around us, there are forces…
All things are made up of molecules When things get heated, they absorb heat energy With more energy, molecules are able to move faster When molecules move faster, the temperature rises What is Thermal Energy Thermal Energy is energy resulting from the motion of particles It is a form of kinetic energy and is transferred…
