Answer to Question 1

Valley glaciers form U-shaped valleys that may have waterfalls leading into them suspended from hanging valleys formed by small tributary alpine glaciers that once fed the main valley glacier. At mountaintops, one might see pyramid-shaped horns standing above bowl-shaped cirques where glaciers sat at valley heads. The cirque may even hold a tarn, a residual lake after all the ice has melted from the accumulation zone. Sinuous rocky ridges (artes) may extend out from the horn, and if the terrain is near the ocean, a steep-sided fjord or two may connect the mountainous, formerly glaciated landscape to the sea.

Answer to Question 2

Till is unsorted sediment deposited directly by glacial ice. Stratified drift is sorted sediment deposited by glacial meltwater.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

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.
