Question

Explain briefly how dolphins locate the distance of an object in the water.

A. Dolphins use their keen sense of smell.
B. Dolphins emit sounds and measure the time it takes for echoes to return.
C. Dolphins rely on their excellent eyesight underwater.
D. Dolphins use magnetic fields to gauge distance.

Answer 1

Dolphins locate the distance of an object in the water through echolocation, by emitting sounds and measuring the time it takes for echoes to return. By analyzing the reflected sound waves, dolphins can determine the distance between themselves and the object.

Step-by-step explanation:

Dolphins locate the distance of an object in the water through a process called echolocation. They emit sounds and measure the time it takes for echoes to return.

By analyzing the reflected sound waves, dolphins can determine the distance between themselves and the object. This method is similar to how bats use echolocation to navigate and find food.
