Answer to Question 1

Deserts are defined as regions where annual precipitation is less than 25 centimeters. A desert is recognized as being a dry place, although it can be either hot or cold.

Answer to Question 2

Water is 800 times denser than air. This observation means that the shear stresses exerted by blowing wind are much less than for flowing water. Sediment grains are also easier to move in water than in air because the grains effectively weigh less in water than in air because of the difference in fluid density.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
