Have you ever wondered why little rain can cause drastic floods? Why rainwater doesn't just stay in one place, it goes with the force of gravity? If you have, you’ve thought about a cycle called runoff. Runoff can be negative and positive. It can cause floods, or water your crops.
The amount of runoff depends on the surface of the Earth. If you have something like pavement you're prone to have more runoff. If you have something like soil, you're prone to have less runoff. Runoff can also be affected by slopes and the ground material.
Runoff water has many sources and flows into many sources. There are multiple reasons we have runoff. Runoff takes place when there is a lot of water that the land can't handle.
For less runoff, we can make
Water has three stages—liquid, gas and solid. Water on Earth can be liquid as rain, streams, or oceans. It can be a solid like hail, ice or snow. It can be a gas like vapor, steam or clouds. As described by the Department of Atmospheric Sciences (2010), the hydrologic cycle is the process of water changing from liquid to gas to solid. The energy of the sun drives the changes to water. When water is heated up, it evaporates, turning into a gas to form steam or vapor. The water vapor rises with warm air that when meets cooler air, condenses to form clouds. These clouds and water vapor can be transported around the world. Precipitation is when water falls to Earth, in warmer temperatures as liquid and in temperatures, as a solid. On Earth, precipitation can evaporate again or infiltrate the Earth to become groundwater. As ground water it can collect in oceans, rivers or on snowy mountaintops and glaciers. It can also be released back into the atmosphere via transpiration, when water evaporates off soil, trees. When water evaporates, the cycle starts again.
There are numerous stages that take place simultaneously in the hydrologic cycle and this includes evaporation. This is when the water alters from a liquid state into a gas. The damp air from the water rises into the atmosphere and when it cools, the vapor condenses and shapes into clouds. But those billows are not the only form the vapors make; it can also materialize as dew, fog and mist, which blanket the Earth, characteristically on a rainy or humid day. Evaporation takes place when water changes from a liquid state into a gaseous state, and ascents out of the pores of the earth and into the atmosphere as a vapor (“How”). While evaporation is taking place, condensation is also occurring. When the temperature in the air plunges, the clouds become heavy and as a result they relieve themselves of the extra weight, which is called precipitation. This produces rain, hail, snow and sleet, conditioned upon the temperate. As the precipitation falls, it enters the surface of the ground and percolates into the soil, which is called infiltration. The more porous the land is, the more the infiltration can take place. However, the ground cannot hold all of that water and floods. The excess rainfall, which is also called runoff that has not been absorbed makes its way into bodies of water, such as small ponds, rivers, lakes and parts of the ocean (“Summary”).
But one can’t look at “water” in a monolithic sense, because not all water is usable for drinking or irrigation. Usable water can be defined, in this instance, as a source that is reliable, consistent, and clean enough to drink or use for irrigation. This includes rivers, lakes, wells, but it does not include oceans or contaminated water. In some circumstances, the water that is at first promising can then become contaminated; water standing in irrigation ditches can become a fertile breeding ground for mosquitoes and other carriers of disease. In addition, the over-use or diversion of water can impact its quality, creating water heavy ...
A watershed is an area of land that contributes water to a river, lake, wetland, bay or any other body of water, small or large. Watersheds are also known as basins or drainage basins, as they do “drain” off into a larger body of water. There are watersheds all around us. Small streams and creeks are also considered watersheds; so even if you don’t know it, you too live in a watershed. Watersheds consist of all surface water, as well as all ground and underground water.
Love has the power to do anything. Love can heal and love can hurt. Love is something that is indescribable and difficult to understand. Love is a feeling that cannot be accurately expressed by a word. In the poem “The Rain” by Robert Creeley, the experience of love is painted and explored through a metaphor. The speaker in the poem compares love to rain and he explains how he wants love to be like rain. Love is a beautiful concept and through the abstract comparison to rain a person is assisted in developing a concrete understanding of what love is. True beauty is illuminated by true love and vice versa. In other words, the beauty of love and all that it entails is something true.
The rise in temperature is having a significant impact on levels of rainfall, which in turn effects water run-off. Satellite observations since 1987 have shown that, as global temperatures have increased, global mean precipitation has increased in parallel at a rate of 7.4 ± 2.6% per ◦C ...

For decades tourists and local beach goers have been flocking to Southern California in search of an inviting environment to relax and enjoy all the amenities a coastal climate has to offer. Yet despite the beauty and breathtaking atmosphere, many unforeseen factors may alter your perspective in regards to how frequently you visit these beach locations. In its current state many beach destinations surrounding the Orange County, California area are susceptible to urban runoff bringing copious amounts of pollution to the waterfront. As it stands urban runoff is attributing to the decline of water quality in numerous locations like Doheny Beach and Poche Beach, which for several years now have remained present on Heal the Bay’s Top 10 Beach Bummers list. With two of Orange Counties own beaches being present on the Top 10 list, it is now apparent that there is a breakdown in the system in regards to policies responsible for controlling runoff headed to the ocean.
Rain in reality is moisture condensed from the atmosphere that falls visibly in separate drops. To get rain, the water condensing in the clouds has to become heavy enough to fall to Earth. To become heavier, some will collide with other droplets and become larger, and others will grow as water condenses out the air directly into the droplet, and some will do so by both methods. Eventually, if the droplets keep growing, they will reach a mass where they can't stay floating in the cloud because they are too heavy and will start to fall as rain. Before it can rain, there must be moisture or humidity in the air. In order for there to be moisture in the air, water must evaporate. The best source for the air's moisture is the oceans and sometimes lakes. Air flows over these large bodies of water picking up moisture as it evaporates off the surface. The air then flows over the land and we feel it in the form of humidity. When air rises, such as up a mountain slope, or when encountering a cold front or warm front, the air cools and the moisture condenses into clouds and rain. Because of this, areas
A Drop Around the World is a fictional book that allows readers to follow a raindrop, named Drop, on an adventure. Drop goes through all of the phases of the water cycle and also visits many interesting places and people. Drop travels to many countries and during its travels, the drop of water goes through the various stages of the water cycle. The language and advanced vocabulary make this book complex and thought-provoking. The text expands the reader’s knowledge of geography and water cycle through pictures as well. I think this book will be a good choice because the author explains the water cycle in the point of view of the raindrop. The students will get an understanding of what a cycle is and how water changes during the cycle.
It follows, therefore, that the presence of wind will also increase evaporation. On still days, water evaporating into the air remains close to its source, increasing the local humidity. As the moisture content of the air increases, evaporation will diminish. If, however, a steady flow of air exists to remove the newly formed vapour, the air surrounding the water source will remain dry, “thirsty” for the future water. Condensation Condensation is the process whereby water vapour in the atmosphere is returned to its original liquid state.
Rain forms when water vapor condenses and falls, the more it condenses the more it falls. Some raindrops are not pure and are filled with other materials, this is known as acid rain. Acid rain is a huge problem all over the world. Acid rain is mixture of chemicals, like fossil fuels and the atmosphere, it then comes down as rain, snow, hail, and sleet. The burning of fossil fuels is the main cause of acid rain. When oil and coal are burned they create sulfur dioxide, nitric oxide, and nitrogen dioxide. (" Acid Rain | US EPA") The mixture of all the chemicals and heavy winds blow the compounds across many borders.
In the warmer summer season however glacial ice goes through a period of melting. The source of the Brahmaputra starts in the Himalayas and an increase in melted-water flowing through its drainage basin will increase channel flow, saturate soils and cause massive overland flow – a major cause of flooding. Another major cause is the cyclonic storms t... ... middle of paper ... ... urther problems some where else.
