Rain is one of the main source of fresh water. Some of the rain water that falls on the land surface may flow into rivers, streams or oceans. This is called runoff water. The runoff water either flows into the rivers or get stored into the lakes to form a fresh water source.
Surface water : After rainfall, water gets collected in the low- lying areas to form pond and lakes. In hilly regions, the runoff water falls from higher areas to form rivers that flows into valleys. The river further flow to seas or oceans. All these water sources from the surface water of the earth.
Underground water : During the summer season or in case of failure of rainfall, people depends on the water from underground sources for domestic and agricultural purposes.
Rain water get collected in the soil by seeping into the gravel and rocks at the bottom. The excess amount of water moves deeper into the ground and fills the spaces in the rocks. This is known as ground water. The level of ground water is known as water table.
