Water Cycle and Pollution

By: Maddy Grawe

What is the water cycle?

The water cycle consists of several key components that interact with each other to create life. The water cycles components include evaporation, condensation, precipitation, and transpiration. Evaporation is the process of liquid water turning into a gas and leaving up into the atmosphere. Condensation is the condensing of water molecules in gas form in the atmosphere. Precipitation is the downfall of liquid or solid water/ice from the atmosphere to the Earth pulled down by gravity. Transpiration is the process of water leaving plants and turning into water vapor.

Water within the Water Cycle

Surface water is any form of water that sits above the ground surface. A majority of the water evaporated in the water cycle comes from the surface water. Runoff is a form of surface water that often create water sources such as lakes, rivers, ponds, and streams from precipitation flowing downhill/mountain due to gravity. When this happens, whatever way a certain amount water flows gets called a watershed. Ground water is any water within the ground. Minerals in the ground often filter and clean out polluted water. Underground water in rock and soil creates aquifers. All these things account for a huge part of the water cycle.

Pollution in the Water Cycle

Pollution is everywhere around us. One of the major forms of it is water pollution, which directly affects the water cycle. There are three types of human caused water pollution, which include chemical, nutrient, and organic/bacterial. There is also naturally caused pollution such as sediment. Sediment Pollution is when erosion takes sediments to places they are not normally supposed to be. Humans, however, can cause erosion therefore creating sediment pollution.

Questions to Consider

When is there too much pollution?

Will the water cycle ever stop?

How can you prevent water pollution?

Why is water pollution getting worse?
