California is in a drought and farmers believe our only option is to take water from under the ground. But‚ groundwater depletion is causing a lot of bad things to happen. It is making the layer of clay above collapse‚ when the clay collapses the dirt above gives way and sinks. This sinking causes sinkholes and is very dangerous. The sinking also damages pipes‚ buckles walls of irrigation canals‚ and cracks homes. Although the sinking is already a big enough threat the water in general could

Global Warming: An exponential threat We currently live in a highly globalized world from every point of view (technological‚ scientific‚ cultural‚ economic‚ communicative‚ etc.) hence‚ one of the most negative effects that generated globalization has been the growing ecological imbalance that has harmed the planet. The global warming has become of the most dangerous threats and challenges to face in the 21st century. Many companies and factories are currently one of the main factors which

This is only expected to rise with major medical and technological advancements on top of more people being born. Humans need various resources to survive; one of the main ones is food.

the reaction time if you had reduced the hydrochloric acid by half? Explain why. 4. What should you have learned about reaction rates? 1. The kind of graph that resulted when I plotted the mL of thiosulfate against the time in seconds was an exponential decay. 2. The graph tells us that the rate of reaction increases when there is more thiosulfate as the reaction took more time when there was less thiosulfate. This is shown on the graph by the increasing volume of thiosulfate corresponded to a

exhibits and Exponential Growth period during Phase A of the given graph. This is visible from the graph because of the distinct J-shaped curve of the graph‚ this indicates that the curve is Exponential. The curve starts with stable phase not seeming to increase because the growth is slow due to the small population known as the Lag Phase. Then the growth build momentum and grows at an accelerating pace until environmental conditions prevent for their growth‚ this is known as the Exponential Growth Phase

Essay ozone depletion is a serious problem presently facing the world. The ozone layer protects humans‚ animals‚ and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair‚ but the problem still exists. The ozone layer is a region of the stratosphere containing ozone‚ or O3 gas. The ozone layer is necessary to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However‚ manufacturing and household chemicals

Ozone depletion and Volatile Organic Compounds Christina Stelmach SCI/ January 20‚ 2013 Christine Snyder The atmospheric issue that I chose to write about is the Ozone layer depletion and the indoor air pollutant is Volatile Organic Compounds. I am going to talk about the cause and effect of each of these issues and also efforts to mitigate the issues. Our Earth’s Ozone layer protects all life from the sun’s harmful radiation. Due to all human activities damage has been done to our

a relation in which each element of the domain is paired with exactly one element in the range. Two types of functions are the exponential functions and the logarithmic functions. Exponential functions are the functions in the form of y = ax‚ where ’’a’’ is a positive real number‚ greater than zero and not equal to one. Logarithmic functions are the inverse of exponential functions‚ y = loga x‚ where ’’a’’ is greater to zero and not equal to one. These functions have certain differences as well as

Choose one of the forecasting methods and explain the rationale behind using it in real life. I would choose to use the exponential smoothing forecast method. Exponential smoothing method is an average method that reacts more strongly to recent changes in demand than to more distant past data. Using this data will show how the forecast will react more strongly to immediate changes in the data. This is good to examine when dealing with seasonal patterns and trends that may be taking place. I would
