CH1 00:58 Meterorology - study of the atmosphere and weather Earth’s motions and energy from the sun act on the atmosphere to produce weather, in  turn creating basic pattern of global climates Weather - (constantly changing): the state of the atmosphere at a given time and place. Climate: the description of aggregate weather conditions, the sum of all statistical  weather information that helps describe a place or region.  Variations, extremes, and probabilities of different types of weather occurring Climate data cannot predict the weather. Climate is what you expect, weather is what  you get The nature of weather and climate is expressed in terms of the same basic elements  (quantities/properties that are measured regularly) 1. Temperature of the air 2. Humidity of the air 3. The type and amount (coverage) of cloudiness 4. The type and amount of precipitation 5. The pressure exerted by the air 6. The speed and direction of the wind These elements constitute the variables by which weather patterns and climate types  are depicted Earth’s spheres: tons of interaction between spheres, spheres aren’t separated by well  defined boundaries, numerous interrelated parts.  Geosphere: solid Earth Atmosphere: gaseous envelope Hydrosphere: water portion Biosphere: Life

Geosphere Solid Earth, that lies beneath the atmosphere and ocean. Extends from surface to center of the earth, depth of 6400km  Largest of Earth’s four spheres Atmosphere Life-giving gaseous envelope surrounding the earth More than 99percent of the atmosphere is within 30km of the Earth’s surface Provides air for life and protects from dangerous radiation emitted by the Sun The energy exchanges that continually occur between the atmosphere and Earth’s  surface and between the atmosphere and space produced the effects called weather W/o atmosphere, Earth would be lifeless and may of the processes and interactions that  make the surface a dynamic place could not operate Hydrosphere A dynamic mass that is continually on the move, evaporating from the oceans to the  atmosphere, precipitating to land, and running back to the ocean again The global ocean accounts for 97 percent of the earth’s water. The ocean covers 71percent of the earths surface to an average depth of 3.8km Hydrosphere also includes (remaining 3 percent of Earth’s water) fresh water found in  clouds, streams, lakes, glaciers, and water found underground  Clouds play a vital role in many weather and climate processes.
