(( 20 points ))
(( earth science ))

create an analogy or example to "show" someone what the each boundary does using non-scientific terms. then explain your reasoning.

your terms are:
- convergence boundary
- divergent boundary
- transform boundary

example: transform boundary is like two people playing tug of war. the pressure keeps building, the rope breaks and then the two people go flying. this works because the transform boundaries are always sliding by each other, building up pressure until something breaks and then the earth shakes.

Convergent boundary analogy - a  bus and a car collide into each  other.

Divergent boundary analogy - two magnets repel from each other.

Transform boundary analogy - two books are sitting next to each other and are touching all along one side. Push one of the books away and leave the other one in place.

Explanation:

The Earth's crust is divided into several hard and rigid tectonic plates that slide over the mantle. These plates have different shapes and sizes. They are in constant contact with each other so the movement of one plate causes the other plates to move. The major geologic features like faults, earthquakes, volcanoes, mountains, ocean basins and the origin of the continents at Earth's surface are due to the  movement of these plates toward or away from each other.

Tectonic plates can interact in three different ways : converge (move toward one another), diverge (move away from one another) or transform (slide past one another). The plate margins are the boundaries where plates meet and they are of three kinds: oceanic-oceanic, continental-continental, and continental-oceanic. Depending on the nature of the plate interaction and of the margins, different types of geologic activities occur.

A convergent boundary (two tectonic plates come together) is like a  bus and a car collide into each  other. When two plates converge, one of the plates sinks underneath the other and forms an ocean trench or a chain of volcanic islands or complex mountains ranges.

A divergent boundary (two plates move away from each other) is like two magnets repel from each other. When two plates diverge, a mountain chain (ridge) develops and seafloor expands or a new sea is born.

A transform plate boundary (two plates slide past each other) is like two books that are sitting next to each other and are touching all along one side. Push one of the books away and leave the other one in place. When transform motion occurs, two rock plates slide past one another at a margin and a crack or fault develops. As a result, an earthquake occurs due to the energy generated by this movement.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
