When there is rain the forests holds a lot of rainfall to the soil through roots of plants. The water then sinks deeper in the ground and replenishes the supply of the water table. If there was the removal of these forests then water from rain would flow simply through the soil surface and not be retained. Another effect may be the water from rain will not stay in the soil at all and the process of evaporation would immediately set in therefore not replenishing water table. This would lead to wells drying up.
The hypothesis of this experiment goes as follows, If we place potato cells in a salt solution, then the cells will shrink. They will shrink because when the salt is added the water in the potato, where there is high concentration, will move to the outside of the potato where there is low concentration.
The lake is about 20 miles long and 8 miles wide. Lake levels and size vary because of heavy agricultural use, and in years of drought. The border of Utah and Idaho goes right across the center of the lake. The lake is 250,000 years old and is formed by Fault Subsidence, which continues today making the lake deeper on the East side.

Treacherous rainfalls are also able to produce landsides. In Snow Facts for Kids, on the website www.sciencekids.co.nz, the highest amount of rainfall recorded in a one year’s time was 25.4 meters or 1000 inches in Cherrapunji, India. Also large amounts of snow can create huge drifts. And snow can also stick to tree limbs causing them to break and fall on houses and cars. Snow can also stick to power lines and cause power outages.
The inability of rain will led to increase heat and that may lead to have dryer soils and that would have a big impact in our agriculture. Productivity will decline. Even though if that happens irrigation to fill water needs could be a way to help the need of rain. The soil of Indiana is a major natural resource that temperature changes will affect, hotter drier summers, would be the main cause of loss soil organic matter and will result an increased soil respiration. Loss of soil will decrease the ability to retain moisture and specially essential nutrients for plant growth.
When acid rain falls, it sometimes raises the levels of acids in certain soils, removing nutrients from the soil that helps plants grow. Because the nutrients are removed from the soil, it makes it hard for plants and trees to resist diseases, insect infestation and bad weather. Acid rain also raises the acidity of steams, rivers, and lakes, which can harm and sometimes kill life in the water. The acids in acid rain also react with the CaCO3 in marble and limestone, which can cause damage to statues and buildings. Lakes with limestone beds are less affected by acid rain because the limestone reacts with the acids in acid rain.
It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees to take up water. Trees' leaves and needles are also harmed by acids and makes trees and plants less able to withstand cold temperatures, insects, and disease. How does it affect animals? Acid rain makes waters acidic and causes them to absorb the aluminum that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.
| Soil Erosion | Tree major practices | Rosa Flores 2/18/2013 | Three major practices that expose soil to erosion and how they can be corrected. Soil erosion is the loss of soil caused by particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrade the soil to a coarser, sandier, stonier texture. The major causes of soil erosion are over-cultivation, overgrazing, and deforestation. They are creating problems to create a more sustainable society but it can be corrected.
Consequences The most conspicuous effect of cultural eutrophication is the creation of dense blooms of noxious, foul-smelling phytoplankton that reduce water clarity and harm water quality (Figure 2). Algal blooms limit light penetration, reducing growth and causing die-offs of plants in littoral zones while also lowering the success of predators that need light to pursue and catch prey (Lehtiniemi et al. 2005). Furthermore, high rates of photosynthesis associated with eutrophication can deplete dissolved inorganic carbon and raise pH to extreme levels during the day. Elevated pH can in turn ‘blind' organisms that rely on perception of dissolved chemical cues for their survival by impairing their chemosensory abilities (Figure 3) (Turner & Chislock 2010).
Thus, the chemical enters the natural food chain. A bug would absorb the pesticide, and be eaten by a bird or other insectivore. That animal would then absorb whatever of the pesticide the bug hadn't metabolised or ejected. From there, it would be passed on through the food chain and be spreaded. It is actually not very useful, because although it kils pests, it does not solve the pest problems permanently( Conditions should be changed to end up this problem.).
