All over our planet, the i ocks and the water are touching and brushing together. Sometimes invisible fragments of rocky minerals are stolen and dissolved in the water. Sometimes larger fragments aie washed away and swept along by running rivers. Most of the worlds water is held in the enormous ocean basins Some is held in smaller hollows to form lakes and streams. But on the continents, a great deal of water is absorbed by always moving unless there their with watei pockets henever they can. Many rocks aie mixtures of harder and softer minerals Seeping water and running water lend to dissolve their softer materials and wash them away. In time, this leaves cracks and porous pockets in layers of limestone. form when Oilier pockets "ravelly pebbles aie sealed together with muddy cements. All these potous locks fill then pockets whenever water happens to be moving in the right dnection. For example, a poition of the rain and melting snow sinks down through the numbly soil. If the bedrock below the soil is shale or some oilier dense layer, it sinks no fai- - is something around to stop it When free to roam, it flow's until it meets its downhill own level. This may be a high mountain lake or the mighty ocean. All this water is on or in the earth's crust, where it brushes against a vast assortment of rocky minerals.

Water, of couise. is fluid. grained sandstones tend to fill stal-lm- cei-la- ther. The water either settles in soggy puddles or washes away in streams. But many rocky layers below the surface are riddled with pores. As the rain sinks down, they absorb it until all their pores are full. More Much Water s Thank goodness those rocks are down theie.
