The ocean is a vast reservoir of kinetic energy, but it's also a challenging place to generate electricity. Which of these does NOT present a challenge when using wave energy to provide electrical energy?

A.)Waves are too inconsistent to be useful

B.)Salt water can corrode metal components

C.)Storms and forceful waves can damage power systems or loosen them from their moorings

D.)Barnacles and other sea creatures can cling to exposed surfaces, blocking intakes and weighing down machinery

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
