increases the acidity of the water. Chronic acidification may reduce the levels of nutrients such as calcium‚ which‚ over time‚ may weaken the fish and other plants and animals in an aquatic ecosystem. Most of the effects on forests are subtle. Acid deposition may influence forest vegetation and soils. Acid rain weakens the trees’ natural defenses‚ making them more vulnerable to diseases. It has been cited as a contributing factor to the decline of the spruce-fir forests throughout the Eastern United

Student Field Report Example Introduction Slightly to the north of Dayton Pond in Wallingford‚ Connecticut‚ just off of Dayton Hill Road‚ there is a small park consisting of a parking lot and two manicured soccer fields (Appendix A). Although we did have goals‚ we had not come to the park to play games. No‚ there were soil pits to be dug‚ something that we at Brown Pit Associates take quite seriously. Fortunately for the soccer teams that occupied the fields‚ we were not interested in the soils

Mangroves are highly specialized ecosystem‚ which are characterized by salt resistant plants growing in the inter tidal areas along sheltered seacoasts and estuaries in the tropical and subtropical regions. India has approximately 31‚5000 ha of mangrove out of which about 65000 ha are along the west coast. Gujarat and Kerala coasts have the most degraded mangroves‚ while Maharashtra‚ Goa and Karnataka have occasional luxuriant pockets. They form extensive and highly productive forests characterized

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

Flowing 2‚350 miles from Lake Itasca to the Gulf of Mexico‚ the Mississippi River is the fourth longest river in the world with a watershed spanning thirty-one states and two Canadian Provinces (Mississippi River‚ n.d.). The Mississippi River provides a suitable habitat to many species because of its suspended-sediment flow regime. However‚ damaged caused to the river by human intervention has caused the sediment flow trends in the 19th and late 20th century to decline. In 1936 to 1950‚ the average
