Volunteering is generally considered an altruistic activity where an individual or group provides services for no financial gain. Volunteering is also renowned for skill development, and is often intended to promote goodness or to improve human quality of life. Volunteering may have positive benefits for the volunteer as well as for the person or community served.
The climate of a location is affected by its latitude, terrain, and altitude, as well as nearby water bodies and their currents. Climates can be classified according to the average and the typical ranges of different variables, most commonly temperature and precipitation. The Bergeron and Spatial Synoptic Classification systems focus on the origin of air masses that define the climate of a region.
