Fish give off a base, ammonia (nh3, as waste. how does the release of ammonia affect the ph of the water in an aquarium? what can be done to correct the ph of the water?

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
