every river system go through three stages of young adults and elderlythe stages of this development depends on the topographic gradient and flowupstream generally have large flow rate and high erosion ratethe lower is usually the older River with multiple bendrainwater does not flow on the surface into the flow, it will seep down to the groundso all the water repellent surface is called groundwaterrainfall precipitation duration is two factors influence the amount of runoffthe biosphere consists of all living plants, animals, and single-cell organismsthe atmosphere is part of the air that surrounds our planetthe atmosphere of our planet is composed of 79% nitrogen gas and under 21% oxygen, carbon-contained small amounts of ddioxin and other gasesthe lithosphere is the solid ice crust covered the entire planet. This crust covering the entire surface of the Earth from the top of Mount everest until the mariana trenchMarine log includes all water on or near the groundNinety-seven per cent of the amount of water on Earth is in the oceans, the remaining three percent is fresh water, three quarters of fresh water in solid and survive in the ice floorthe water cycle is the center of attention of Hydrogeology This cycle has no beginning nor end the water evaporates from the oceans and land surfacethe steam is taken up into the atmosphere to condense and reduce the water to the ground and oceans rainwater does not flow on the surface runoff will seep down to the ground so all the water repellent surface is called groundwater rainfall duration rains are two factors that affect the amount of the flow
