Recommended: Question about water cycles
Water is always on the move. Rain falling where you live may have been water in the ocean just days before. And the water you see in a river or stream may have been snow on a high mountaintop.
Water can be in the atmosphere, on the land, in the ocean, and even underground. It is recycled over and over through the water cycle. In the cycle, water changes state between liquid, solid (ice), and gas (water vapor).
Most water vapor gets into the atmosphere by a process called evaporation. This process turns the water that is at the top of the ocean, rivers, and lakes into water vapor in the atmosphere using energy from the Sun. Water vapor can also form from snow and ice through the process of sublimation and can evaporate from plants by a process
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”).
In the video series Water’s Journey: Hidden Rivers of Florida, the narrator and scientists discuss the connections between human society above ground and the quality of aquifers below ground. The first part of the video series discusses the preparation and introduction of the mission of Wes Skiles, Tom Morris, and Jill Heinerth. The video begins with discussing connections between human society above ground, and the quality of aquifers below ground and how water is such an important part. The narrator also defines Earth as a water planet, due to the fact that it is the most important resource and all living things depend on it. Then, the movie begins discussing Florida’s aquifers and the process of how water can travel through the aquifers
... of dust in the air. It condenses when it hits the dew point. When it condenses it becomes a liquid again or turns into either ice, hail, rain, sleet or, snow. These water particles eventually come together and form clouds. Precipitation in the form of ice, rain, sleet, snow and hail comes from clouds. Clouds move around the world, propelled by air currents. Water vapor is also emitted from plant in a process called transpiration. Excessive rain or snowmelt can produce overland flow to creeks and ditches. Runoff is visible flow of water in rivers, creeks and lakes as the water stored in the basin drains out.
“Round and Round the Water Cycle” by Barbara A. Bradley is a great read about teaching the water cycle to K-2 elementary school students. She talked about how the water cycle is important to teach student at a young age because it helps them have a more sophisticated understanding later on in their school. In Bradley’s article, she lays out a ten-day unit on the water cycle, including pictures, diagrams, resources, and Ms. Bey’s (the teacher who conducted the lesson) findings when doing the lesson with her students. Ms. Bey went through the four components of the water cycle in those ten days. She had her students keep a science journal and write about their findings when they discussed evaporation, condensation, precipitation, and collection. Throughout the lesson that was taught, the students where asked questions, asked their own questions, and recorded everything in their journals. The students were also introduced to new vocabulary and learned what the new vocabulary meant through books and science experiments
The global pattern of atmospheric heating and circulation is the high precipitation in the tropics which is produced by high rates of evaporation and subsequent concentration of water vapor in ascending air masses. Energy from the sun heats up earth but unfortunately it doesn’t distribute it evenly across the surface of the earth. The tropics receive more heat radiation than they produce the arctic or the polar region produce more radiation than they receive. The clouds formed in this way produce the heavy precipitation associated with the tropics. The mechanisms of high precipitation at temperate latitudes is produced when warm, moisture-bearing subtropical air meets cold polar air, which forces condensation of the water vapor in the subtropical air mass. Precipitation is mainly to do with the temperature of the air. Higher the airs temperature the more moisture it can hold, and vice-versa. Since the tropics are warmer the air holds more moisture and won't lose it until it interacts with colder air, which is usually at mountains as cold air is forced up into the hot air by the ...
Once upon a time high above the earth, fluffy white clouds drifted through the atmosphere. In the clouds lived a family Droplet of water, round and content with life. For as long as I could remember, I spent my days lying on my back, relaxing and soaking up the sun's warm rays. One day, I took my usual place in the sun but the light didn't seem to be as bright. In fact, as the day went on, it grew darker and darker, loud claps of thunder shook the cloud, and the Droplet felt as if he were getting so heavy he could hardly move. This is called precipitation.
Rainwater contains more gas than groundwater, especially the content of CO2 and O2. At the transport process, water vapor is mixed and dissolved gasses and other compounds in the air. Therefore, rainwater contains dust, bacteria, and various compounds present in the air.
Water vapor goes into the air, and releases latent heat of condensation. The water vapor turn into clouds and rain warming the surrounding air. The hurricanes winds then spiral around and around and push the water vapor into the
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.
Air is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, water vapor, and other gases. Air molecules are in constant motion. As they move, they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all of the air molecules in the Earth's atmosphere pressing down on the Earth's surfaces. We can measure air pressure to help us predict weather conditions around the world. Temperature also affects air pressure because air contracts when it cools and expands when it is heated. So if air above a region of Earth cools, it does not extend to as high an altitude as the surrounding air. In this case, its pressure at higher temperature is lower than in the surroundings even when the pressure at the surface is the same as in surrounding areas. Then air flows into the cooler region at high altitude, making the total weight of air above the region greater than in the surroundings. This is a "high". The cool air descends to the earth's surface. Near the surface, the falling air spreads out,
A naked male figure rested upon a stone dais, within a small room with stone walls. The dais was cracked at the base, causing it to slant down towards the floor. But the floor couldn't be seen, as murky water had filled the room, up to the figure's feet. His eyes opened, a breath of air filled his lungs.
The hydrosphere contains all the Earth’s water found in the atmosphere, oceans, lakes, streams, and groundwater. The Earth became cool enough for liquids to form early in the planet’s history. A lot of people make dams, reservoirs, and levees to try to hold, move water which pollutes and damages ecosystems and kills wildlife. Water is everywhere under the ground, but you can only use it if it is being contained in an aquifer. Surface water pollution is a major issue in the United States and elsewhere around the world.
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.
The amount of water that is on earth at any one time remains fairly constant because the water is moving form one reservoir into another such as river to ocean or ocean to atmosphere. This cycle involves the exchange of energy causes a change in temperature. This is why when evaporation occurs, it takes energy from its surroundings and cools the environment. While condensation occurs energy is released and the surrounding environment becomes warmer. The atmosphere is a mixture of nitrogen, oxygen, and other gasses that surround the earth. The atmosphere is made up of five layers known as the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. The troposphere is the lowest layer of the earth’s atmosphere; it is also where all weather on earth takes place. The stratosphere is the second layer of the atmosphere, right above the troposphere. Above the stratosphere is the mesosphere and above that is the troposphere. The uppermost region of earth’s atmosphere is the exosphere. The air in the exosphere is extremely thin and almost the same as space. One of the many reasons the earths atmosphere is important is because it blocks
It includes the water found in lakes, reservoirs, and groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today.
