Document Summary
Mass wasting (water on steep slopes, slopes covered in soil and dirt, landslides, flowing matter causing floods) Habitats (wetlands, etc don"t want all frogs to die) Global warming (climate change has a big water component because of water and temperature) Of the 2. 8%, 2. 15% is for glaciers and. Running water is the dynamic agent for many processes such as erosion, sediment transport and deposition. It is also essential for electricity generation (heps). Evapotranspiration: this is the sum of evaporation and plant transpiration from earth"s land and ocean surface to the atmosphere. Oceans lose more water by evaporation than they gain by precipitation. Land surface receives more water as precipitation than it loses by evapotranspiration. Continuous records are sampled over specific time periods (min, day) to obtain maximum, minimum and average over that time period. System: a region with defined boundaries that can receive input and provide output of a conservative quantity (such as mass, energy)
