Document Summary
Bring a pen + student id + basic calculator. Hydrograph: plot the change in flow, compares time and amount of precipitation. We live on a planet of water --> about 70% of the earth"s surface is occupied by water, water is fundamental to life and without it, there would be no biological processes and would not influence geomorphic processes. All three phases of water (liquid, ice, gas) are fundamental to our living (it also influences the hydrological cycle) Freshwater --> 30% is in ground water, 70% is in glaciers and 1. 2% is located in the surface. Total global water --> 96. 5% is in oceans, 0. 9% is in saline water and. Precipitation --> how water is returned to land. Precipitation: is one of the key drivers in the hydrological cycle, since it returns water from the atmosphere to the land surface, it would also deliver rain, snow or hail. It also delivers different fluxes --> evaporation, transpiration and surface run off.
