The local climate of specific place or habitat, as influenced by landscape features.

The planting, cultivation, and harvesting of a single species of crop in a specified area.

A popular term used to describe the heating effect due to the trapping of long wave (length) radiation by greenhouse gases produced from natural and human sources.

A body of water that contains brackish (highly saline) water that forms layers of differing salinity (stratifies) that absorb and trap solar energy. Solar ponds can be used to provide heat for industrial or agricultural processes, building heating and coo ...
