How important is this cycle to Earth? Essay

Evaporation is the transformation of liquid water into water vapor.On the other hand, if the water does not rise to the air through evaporation after a typhoon, cyclone, or a massive storm, then most parts of the Earth would remain flooded and eventually, all the lands would be submerged underwater.Basically, runoff water remains on the surface and then subsequently flows to large bodies of water such as oceans, rivers, lakes, and seas among others (Encyclopedia of the Earth, 2007).The hydrologic cycle or the water cycle is basically the incessant and continuous flow and movement of water, beneath, above, and on the Earth’s surface (Encyclopedia of Earth, 2007).One example is sublimation which is the direct transformation of solid water,...

Design And Construction Fundamentals Of Earth Dams Environmental Sciences Essay

Spillway plays an important role in earth dam since it allows excessive water to flow without overtopping the dam wall.Although the downstream face of the embankment is not affected by reservoir water, it may get eroded by heavy rain flowing down the face of the dam, causing the formation of gullies and finally collapse of the whole dam.As for foundation failure, it occurs because of excessive pore water pressure which reduces the strength of the soil which it may not be able to resist the shear stresses induced by the embankment.Earth dam is built for the purpose of storing water and is made of compacted earth.Earth dams, also called earthen or earth-filled dams are generally built in or near drainage line which has the variety of purpo...

Earth from Space Essay

In general, it can be said that the astronauts took much notice of the more general features of the earth, focusing on the earth as a whole and not in terms of the multitude of land and water varieties that comprise it on closer inspection.For instance, one can easily recognize the seemingly boundless bodies of water occupying the larger regions of the earth.Since much of the earth is covered in water, and much of the planet’s water comes from the Pacific Ocean, it is only expected from astronauts to immediately take notice of the Pacific.Earth from Space.Satellite images also reveal how almost a third of the earth is comprised of those vast quantities of sea water, thereby prompting observers to not fail to see the deep blue blanket of ...

Investigation into the Importance of Titan

There is also speculation that this process didn’t occur on the Earth at all and that life had an extraterrestrial origin, being carried to Earth from space in comets, meteoroids and dust particles.The essential conditions for life, at least as we know it on Earth, are water, supplies of the necessary chemicals from which living cells are constructed and energy.Ice has a higher albedo than water and if a large enough hole was made the decreased albedo could have caused a runaway melt.7 It is known that Titan is comprised mostly of ice, but early in its existence, when it resided in a hotter Universe, it is possible that it had liquid water on its surface.This is a crucial point because all known life requires liquid water as a solvent.

The Earth in Space ‘Tides’

Tide occurs because of gravitational pull of various objects on Earth; primarily gravitational force of the Moon and Sun at the same time rotation of Earth.In diurnal tides, one high and one low water tide occur each day and can be seen on Northern Gulf of Mexico and SE Asia.The word ‘tide’ is used for defining the alternating rise and fall of water in sea level with respect to land.In semi-diurnal tides, two high and two low water tides occur each day and can be commonly seen on Atlantic coasts of the United States and Europe.When the Moon is in line with the Sun, new Moon (between the Earth and Sun) and full Moon (opposite side of Earth), the gravitational forces act in a line to produce tides higher than at other times.

The Water Cycle

Water that runs off into rivers flows into ponds, lakes,or oceans where it evaporates back into the atmosphere.The cycle continues.Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into the vapor.The earth has a limited amount of water.That water keeps going around and around and around in what we call the “Water cycle”.It is the only way that Earth can be continually supplied with fresh water.The sun is the most important part of renewing our water supply.It can be solid (ice),a liquid (water), or gas (water vapor).Clouds lose their water as rain or snow,which is called percipitation.Condensation is water vapor in the air gets cold and changes back into liquid, forming clouds.If heat is taken away f...

Ocean/atmosphere general circulation Coursework

The two systems work hand in hand to regulate temperature, circulation of water and influence weather and the climate.Longitudinal circulation features, on the other hand, are caused by disparities in temperature, which is in turn influenced by the differences in specific heat capacities of water and land.This, therefore, explains how flow in the atmospheres of Venus, Earth, and Jupiter are consistent with their relative rotation rates and is attested by practical fluid experiments.The effect of rotation of Earth also generates another important frictional force.Ocean and atmosphere circulation, the distribution of water and land masses as well as the topography of land moderates the worlds’ climate.
