The bending of light rays happens when the light rays hits an object. It moves in various directions thereby letting us to view that object that the bounced off.
<u>Explanation:</u>
Light gets reflected to human eyes and other body parts, when they hit a flat mirror. The bouncing off is not accurate in human heads and other parts that faces the mirror. The refracted rays from human bodies starts to hit at different angles in the mirror and are reflected back accurately. This is the reason for the backward appearance of mirror images to human eyes.
The light is reflected backward to the point behind the mirrors that are of Convex type. Hence the obtained image will be smaller and farther that its originals. The light will be drawn into the mirror's center point and hence the resultant image will be larger than the original object because of the light reflected by a concave mirror type.

Explanation: Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption, salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry.
<span>Some of the people who live in the Sahara raise crops on irrigated land in an oasis. Others tend flocks of goats, sheep, and camels. These herders find grass for the stock along the desert's fringe or where sudden rains have fallen. They live in tents so they can move easily as soon as the grass is eaten in one place.</span>
