... as acidic, After many rain falls of Acid rain, the pH of a normal lake ( 5.8 ) to 4. Acid Rain has been known to reach the acidicy of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will i ...

... the beginning of time humans have been obsessed with the idea of where life comes from, and how it is created. Charles Darwin originated the idea of evolution. Another theory that is used to explain the origin of life is the big bang theory that states that life was created from a cosmic explosion. Yet another theory on the origination of life is the existence of God and that God created the earth and all of the life on earth. Victor Frankenstein is exactly like the scientists of today. Victor Frankenstein is trying to make a human being from other, deceased human beings, this could be compared to clonin ...

... the planets. The forming sun and planets were made up mostly of gas. They contained much more gas than dust. The earth was far bigger than it is now and probably weighed 500 times as much. The large body of dust and gas forming the sun collapsed rapidly to a much smaller size. The pressure that resulted from the collapse caused the sun to become very hot and to glow brightly. The newly born sun began to heat up the swirling eddy of gas and dust that was to become the earth. The gas expanded, and some of it flowed away into space. The dust that remained behind then collected together because of gravity. Altho ...

... thickening of the blanket is causing more heat to be trapped resulting in the warming of the earth. One great example of the Greenhouse Effect is the planet Venus. Venus's atmosphere had a thick layer of CO2, giving the planet's surface a temperature warm enough to melt lead. So What Does All This "Greenhouse" Stuff Have To Do With Me? As the temperatures rise, the waters get warmer and begin the melting process of the polar ice caps (Popular Science). Long term predictions of Global warming say that the melting of the polar ice caps will continue causing ocean waters to rise, resulting in massive coastal flood ...

... of harmful gases, liquids, or solids. , known as smoke pollution for many years, resulted from coal combustion (Hodges 526). Smog has been a problem in coal-burning areas for several centuries. Smog finally decreased when coal combustion was replaced by oil and gas combustion. is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. Particles also reduce visibility by ...

... According to the World Health Organization we began to see what AIDS truly was in the late 1970’s to early 80’s, mostly in men and women with multiple sex partners located in East and Central Africa, but also in bisexuals and homosexuals in specific urban areas of the Americas, Ausrtalasia and Western Europe. Aids was and is spread still through infected hypodermic needles which drug abusers are affected by, but also through transfusion of the blood and its components. And sadly, whenever a mother is infected, the unborn child will almost positively receive the virus before, during, or after the pregnancy. ...

... numerous. The reason for this recent surge in interest can be traced to the truly strange nature of quantum mechanical ideas. Quantum physics amounts to much more than a theory of atomic and subatomic processes, it represents nothing less than a complete transformation of our world view. "Its [quantum physics] implications for the nature of reality and the relationship between observer and observed are both subtle and profound. (Barenco)" A description of the world in which an object can apparently be in more than one place at the same time, in which a particle can penetrate a barrier without breaking it, in w ...

... to produce leutinising hormone (LH). As LH increases the size of the follicle increases until an egg is released. The corpus luteum formed in the follicle secretes progesterone that prepares the lining of the uterus for pregnancy. If fertilisation does not occur the lining of the uterus is discharged from the body in the process called menstruation. What is the birth control pill? The combined oral contraceptive pill (the pill) is a reversable, hormonal method of birth control. The pill consists of a mixture of two synthetic hormones similar to oestrogen and progesterone, the woman’s natural hormones which re ...

... to affect a few over that age. The peak age of those affected are eighteen to twenty-four months. Eighty percent of the cases involve children ages four and under. As shown in Figure 1, those affected are children usually age four or less. The graph of Figure 1 clearly shows that there is the greatest percentage of those diagnosed at the age of three or less. is very rare over the age of ten and any time that it is diagnosed to a patient above that age it should be interpreted with suspicion. The diagnosis may not be completely accurate because there is still as of yet no definitive way to test for , only the doctor ...

... or are they born like humans, and thus will they die? The answers to all these questions can be summed up in two words; stellar fusion. Therefore one can begin to understand the stars by understanding what fusion is, how it affects the life of a star, and what happens to a star when fusion can no longer occur. The first question one must ask is, "What is fusion?" One simple way of explaining it is taking two balls of clay and mashing them into one, creating a new, larger particle from the two. Now replace those balls of clay with sub-atomic particles, and when they meld, release an enormous amount of energy. Th ...
