Climate

•Weather is short-term changes in the atmosphere, such as changes in temperature, air pressure, humidity, wind, and precipitation. Climate is the average weather pattern of an area over a long period. •The differences between weather and climate can be summarized as follows: Weather Climate •Weather patterns are caused by the flow of the atmosphere. In the temperate zones, weather conditions usually move from west to east. •The seasons—summer, winter, spring, and fall—are cycles of weather cause…
