what do water come from?
<answer> It comes from rain which has soaked into the soil and gradually been absorbed by porous underground rocks such as chalk and limestone. <context> Below ground we take water from stores called ‘aquifers’ – they may be out of sight but they are a critical source, providing three-quarters of all your water. The water in the aquifers comes from rain which has soaked into the soil and gradually been absorbed by porous underground rocks such as chalk and limestone. Once stored within these sponge-like rocks the water can move through pore spaces towards springs, rivers or the sea, or it can be pumped up to the surface.
