Answer
Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.
Explanation
Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.
The correct answer is a law
Laws explain what occurs, not why it occurs. This is a law because it states that a limp stalk of celery will become crisp if put into ice water. There is no explanation why or how it occurs, only that it will happen.
Answer:
10 meters/second.
Explanation:
Unladen swallow consists of two species are <em>Hirundo domicella </em>and the <em>Hirundo spilodera</em>.
The average speed of unladen swallow comes out to be 10 meters/second. The maximum speed can go upto 13-14 meters/second. The speed of unladen swallow can be calculated by the formula given by Graham K. Taylor. According to graham the speed of unladen swallow is 3 times of the product of frequency and amplitude. ( v= 3fA, v is velocity, f is frequency and A is amplitude).
