Answer to Question 1

The Indian plate has moved northward into Eurasia, causing compression. First, there was subduction
of the seafloor that separated the two continents, which formed continental arc volcanoes. Then, when
the continental plates met, India continued to push into Eurasia. The motions resulted in thrust
faulting, reverse faulting, and folding, which thickened the crust to make the mountains.



Answer to Question 2

An orogeny is an episode of mountain building. A theory of mountain building must account for many
things: the long narrow ranges that occur at plate boundaries, intense deformation, granitic plutons and
regional metamorphism, and the uplift of shallow and deep marine sedimentary rocks

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease. However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.
