Scientists use the light year because nothing can travel fast than light. Therefore, in any given time frame, light will travel farther than any other substance or particle in the universe. For more precise measurements, scientists use astronomical units. One AU is equal to the distance between the earth and the sun. For anything less, scientists usually use kilometers. For extremely large, interstellar distances, light years are very useful. You wouldn’t want to measure the distance between Earth and Proxima Centauri in kilometers or even AU. The lightyear gives a simple, relative measurement.

Which of the following best explains how a hurricane can increase an area’s susceptibility to future storms?
spayn [35]
<h3>Correct answer choice is:</h3><h2>d.  Erosion caused by hurricanes can leave coasts more exposed to storms. </h2><h3>Explanation:</h3>

Important erosion, rapture, and removal of solids happen through storms. Beach erosion is a typical consequence of the high waves that transpire when hurricanes pass onto land. The decline of sand makes the beach to grow narrower and deeper in elevation. Storm loops take the sand offshore, keeping and depositing the sediment in great sandbars.
