Question

WHICH ONE OF THE FOLLOWING SITUATIONS WOULD YOU EXPECT TO CREATE THE HIGHEST WAVES IN THE OCEAN

A.a 50 –kilometer-per hour wind blowing for 5 hours across a 100-kilometer-wide area of ocean/.

B.a 50-kilometer per hour wind blowing for 10 hours across a 1000 kilometer wide area of ocean.






a 100 kilometer per hour wind blowing for 5 hours across a 100 kilometer wide area of
ocean.



A 100 kilometer per hour wind blowing for 10 hours across a 1000 kilometer wide area of ocean

Answer 1

Of the two choice you have, I believe that answer B is correct , if choosing between A & B; if the other two responses were to be labeled C & D, respectively, the correct answer would be D.

According to Wikipedia:

[edit] How waves are formed and measured

A wave creating spray.The great majority of waves one sees on an ocean beach result from distant winds. Three factors influence the formation of "wind waves":

Windspeed
Length of time the wind has blown over a given area
Distance of open water that the wind has blown over; called fetch
All of these factors work together to determine the size and shape of ocean waves. The greater each of the variables, the larger the waves. Waves are measured by:

Height (from trough to crest)
Length (from crest to crest)
Steepness, or slope (either the angle between crest and trough, or the "steepness ratio," of the wave's height to its length)
Period (length of time between crests)
There are theoretical limitations, however, for each variable. The smaller the fetch, the smaller the largest wave can be for a given wind speed, regardless of how long the wind blows.

Answer 2

a 100 kilometer per hour wind blowing for 5 hours across a 100 kilometer wide area of ocean

Answer 3

The last one. Because the more distance the wind blows, the more affect it will have on the water. This is the use of the term "fetch". The distance over which the wind blows over a body of water.

I'm sure there's some math to use, too, but I don't have time for that so I'm going with my gut instinct.

Answer 4

nicely permit me in basic terms whip out the ole McDougal Littell Earth technological expertise e book I even have in my closet o wait, maximum folk answering this have not got your textbook the questions could be severe high quality
