Evaporation, Transpiration and Sublimation
The Sun is the powerhouse of the Earth’s water cycle. During the daylight hours the energy from the Sun heats the air and the surface of the ocean (Bethea, 2011). The energy from the Sun breaks the bonds of the water molecules, which results in liquid molecules of water evaporating from the oceans and water bodies and rising into the atmosphere as a gas known as water vapour (Graham, Parkinson, & Chahine, 2010). The water vapour molecules in the atmosphere are pure water, because salt and other particles remain behind (NASA, n.d.). NASA (as cited in Bethea, 2011) estimates almost 90% of water vapour in the atmosphere comes from the oceans and water bodies.
The remaining 10% of water vapour in the atmosphere is the result of transpiration by
plant vegetation (Graham et al., 2010). Transpiration occurs as plants take in ...

..., it would be interesting and beneficial to have small groups draw and label a picture of a river showing where it starts and ends as well as the direction of the current (Dove, Everett & Preece, 1999). Vygotsky (as cited in Eggen & Kauchak, 2010) theorised that learning is enriched when it takes place in a social context. Group work allows students to become cognitively engaged in activities and discussion, enhancing the learning experience. Giving students equivalent high–level tasks supports peer scaffolding, as more knowledgeable peers scaffold the learning of other group members (Eggen & Kauchak, 2010).
There is no separate curriculum for children with diverse abilities like James. Instead, the diverse nature of students in any classroom requires the teacher to support all students to succeed by modifying and accommodating language and lesson plans as necessary.

- Week 2 Essay 1 Kimberly High Water is one of the most critical resources on the Earth that most of us take for granted. When it comes to biological system, water also plays a significant role. Describe the properties of water as they relate to biological systems. We have learned through our reading these past two weeks that live evolved from water as single celled organisms and then gradually through time evolved to land, so it would make since that water would play a very important part of the makeup of many living things on this planet....

- ... There is no set beginning and end of the water cycle. Nonetheless, there are three main necessary components of the cycle which include evaporation, condensation, and precipitation. During the process of evaporation water changes from a liquid state to a gaseous state. The process of evaporation “provides nearly 90 percent of the moisture in our atmosphere” (The Water Cycle). In order for evaporation to occur, heat must be present. Just as water boils and evaporates faster when heat is applied than it would if you were to only place a pot of water on the stove....

- Water is essential for humans and organisms to live “Drinking water, “2008). Water covers most of the world and makes up more of the world than land. Water comes from different sources. Water may surround us but there are still shortages. Water allows us to live but it could be harmful to our bodies when polluted. Humans and natural disasters can cause damage to the water supply It is important to conserve water whenever possible (“Drinking Water, “2008). Oceans make up two-thirds of the Earth (“Drinking Water,”2008).... [tags: Drinking Water Shortage]

- ... “Since the 1800s, concentrations worldwide have increased from approximately 280 ppm (or 0.028%) to around 365 ppm (0.0365%). The increase seems trivial, but it also means that some 3 gigatons (3 billion metric tons) of are being added to the atmosphere every year” (“The Greenhouse Effect”). For example, United States produces almost two billion tons of carbon dioxide by burning fossil fuels to make electricity (MacMillan). Studies show that the average temperature of the earth has increased rapidly over the past fifty years (MacMillan).... [tags: Global warming, Earth, Greenhouse gas]

- ... Human factors have a massive effect of the increasing water scarcity on Earth. Firstly, overuse of water is a very key issue which must be dealt with. Water is being overused on people, land, animals and many others things. Clean drinking water is also used for recreational things with no concern for the effects that it may have on the world around them. Secondly, water pollution is a huge problem. Humans only have 1% of all the water in the world which can be consumed yet so much of it is wasted through pollution in the forms of oil, chemicals, faeces and litter....

- The Earth spins around an axis. The Earth takes (a bit more than) one day to go around once. This axis is pointing off somewhere in space. This axis (mostly) doesn’t move. At the same time, the Earth is orbiting the Sun. It takes (a bit more than) one year to go around once. The plane of the Earth’s orbit (mostly) doesn’t move. The spin axis of the Earth’s daily rotation is not perpendicular to the plane of the Earth’s orbit.It is tilted (approximately) 23.4 degrees. The angle of tilt (mostly) doesn’t change....

Opposing efforts to repeal polluter pay laws, Senator Nelson use tax money to promote spills clean up instead of polluter punishing (Nelson, n.d.; OnTheIssues, n.d.). To address consumption of oil, Senator Nelson supports raising standards of CAFE and using alternative fuels. Alternative energy financing through the government is also supported by Senator Nelson (Nelson, n.d.; OnTheIssues, n.d.).... [tags: Global warming, Earth, Greenhouse gas, Atmosphere]

- In today’s society, anywhere from Hong Kong to Detroit, Michigan, a major disregard to Earth and its inhabitants, substantial resources, and well-being has been created; in other words, the Earth has been taken advantage of. With all earth’s inhabitants being unconscious of their actions and how it directly effects Earth, we have unknowingly increased the amount of carbon dioxide (CO2) in our oceans, atmosphere, and planet in general. With this detrimental amplification in the amount of CO2 on Earth, we, as inhabitants to this infected planet, should show more concern with the Earth’s temperature, phases and stages, and reactions we have self-created....

- Carbon dioxide is an important gas that is vital for plant life. This compound is made of a carbon atom and two oxygen atoms. Only 0.0397 of the atmosphere is composed of carbon dioxide. Even though carbon dioxide only makes up a small percentage of the atmosphere, lately increases in the amount carbon dioxide released into the atmosphere have shown to cause an adverse effect on the earth. The rise in amount of carbon dioxide in the atmosphere has caused the earth’s temperature to steadily rise.... [tags: Global warming, Carbon dioxide, Earth]

With ice melting that means glacial retreat is in effect to and is one of obvious effect of global warming. Only 25 glaciers bigger than 25 acres are now found in Montana 's Glacier National Park, where about 150 glaciers were once found, according to the U.S. Geological Survey. A similar trend is seen in glacial areas worldwide..(Effects of Global Warming). With the retreat of glaciers, fresh water will soon be restricted in some parts of the world that rely on that fresh water from the glaciers.... [tags: Water, Earth, Polar ice cap, Climate]
