Essay 1. final exam

The water cycle. WOW so much to say about it. Like everything the water cycle includes, analyze the flow of water, and features and process including the cycles of flooding, erosion, and deposition as they occur naturally.
Firstly let’s talk about what the water cycle includes; it includes evaporation is the process at which the water changes from a liquid to a gas or vapor. Why does the evaporation occur? Well it occurs because heat is necessary for an evaporation to occur. The energy used to create the evaporation is used to break the bonds that would hold the molecules together. This is primarily why the water cycle easily evaporates in a boiling point. Transpiration is the process by which the moisture is carried between the plants from the small pores on the underneath of leaves. Condensation is the process of a water vapor in the sir is changed to liquid water. Condensation is very important to the water cycle because it is responsible for the formation of clouds. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, or hail. This is primarily important in the water cycle because it’s the delivery of atmospheric water to the Earth. Infiltration remains in the shallow soil layer where it will gradually move vertically or horizontally through the soil and subsurface material. Surface runoff is the water that returns from the Earths precipitation and runs off the surface of the land and flows down the hill and goes into stream, rivers, and ponds. Through the surface runoff much of the water returns to the river, streams, and ponds again. Groundwater is located beneath the ground surface in a soil pore spaces. Groundwater is thought of as liquid water flowing through shallow aquifers.
Secondly it’s about the watershed, and the surface features, for example lakes, streams, and wet lands. A watershed is an area on land where all the water falls in it and the drains and off it goes to the same place. It can be as small as a footprint. Many large watersheds contain another smaller watershed. A stream flow is changing all the time, minute by minute.
Lastly but not least. Erosion is gravity driven process that moves so Deposition is the final step in the erosion depositional system. The smaller particles settle more slowly than the larger ones do.
