Weather Weather Brenda Lewis George M. Pullman Elementary School 11702 S. LaFayette Ave. 11311 S. Forrestville Ave. Weather is the condition of the atmosphere around us. We see and feel the weather in the wind, rain, sunshine, frost, or fog. Atmosphere is the blanket of air around the earth.
Wind is defined as moving air.
Atmospheric pressure pushes downward and affects everything on the earth, including your body. You would be crushed by this force if your body did not have its own internal forces which push outward. One body force that you may be familiar with is air in your lungs. The students should conclude that wind is moving air. Pressure is defined as force per unit of area, and it pushes against the earth's surface all the time, but air is constantly moving and changing so the amount of pressure it exerts on any one particular place varies.
