The rock cycle
I. what types of rocks are affected by volcanoes and how are they affected/formed?
A. "igneous rocks begin as magma in the rock cycle" "when lava cools enough it solidifies and turns into igneous rock" (Peter 44).
1. Close your eyes. Now imagine a bowl of ice cream; take that bowl of ice cream and pour some Hershey shell on it. At first the liquid drips down the ice cream and then it hardens and solidifies and becomes solid! Just like lava when it hardens into an igneous rock!
2. In other words, lava is the first stage of the rock cycle for igneous rocks and when it cools from being out on the surface it hardens to rock because it is too cold for it to be liquid.
B. igneous and metamorphic rocks are all kind of like cousins. (Molly 4).
1. you see, the rock cycle starts as lava. The lava reaches surface and becomes an igneous rock! Then due to weather and erosion it becomes a sedimentary rock (although that doesn't have to do with volcanoes). Then it sinks back into the earth over time and due to pressure and heat (sometimes from magma) it becomes a metamorphic rock. Then if it gets too near to magma it will melt and once it reaches the surface it will harden and become an igneous rock and start the cycle all over again!
2. The rock cycle is like cousins because they all come from the same process. Just like cousins all come from the same grandmother
C. in other words making a metamorphic rock with the help from magma is like making a grilled cheese sandwich because, you all ready have the bread and chesses but, you need the help from an oven or grill to make it all work. (Peter 45)
1. Intense heat such as magma from volcanoes helps to create a metamorphic rock.
2. So when a couple rocks are next to each other deep ...
is war fought with chemicals. The development of chemical weapons and defenses against these weapons are usually considered together in military training. These weapons can be designed to kill large numbers of people, disable them for a while, or destroy their food supplies. The weapons are usually effective without destroying property. Chemical ag...

The world is an orb of life. In its limited space all life forms compete to hold their own position. As Darwin concluded in his theory of evolution, ?only the strong and most advanced survive, while the weak perish and are pushed aside.? Evolution, the theory we use today to fuel our need to win and succeed in any organized competition. It is t...
For centuries, man has wondered on his position in the universe. Is he alone? Is he the divine creature? Is he descended from an ape or a godly being? Finding its major roots just recently after World War II, the idea of extraterrestrial life existing and visiting our planet has held us captivated. The probability of alien visitors, although not en...

There are 7 periods and 18 groups. The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869[1], who intended the table to illustra...
