Answer:

27,000

Explanation:

The provided statement talks about an estimate of energy release by an Earthquake with a magnitude of 4 to a magnitude of 7. According to the statement, for the moment magnitude scale, 31.5 times more energy is released with increase of one magnitude scale. Therefore, if we take a rounded value of 31.5 as 30 and multiply it three times (30 X 30 X 30) to represent 3 scales (4 to 7) on moment magnitude scale, we will get 27,000 times more energy.

NeTakaya

Answer:

The correct answer is - B. The seeds are in berries that are eaten by birds and dropped as waste away from the plant.

Explanation:

The mountain ash trees contain red berries fruits that attract birds and other organisms. These birds eat these berries and eat berries and fly over the hills or mountains and after digesting they drop the seeds of these berries with the digestive waste. These berries grow on the mountains far from the original source as birds carry them by flying away after eating.

Thus, the correct answer is option B.
