Thank you Ms. Sue

DHGAMES is right, I got 100%

1. The correct answer is B. The water cycle is the unending circulation of Earth's water supply. This includes processes such as evaporation, condensation, precipitation, and the flow of water through rivers, lakes, and oceans.

To arrive at this answer, we can eliminate options A and C because they only refer to specific aspects of the water cycle (distribution of drinking water and recycling of water after industrial use) rather than the entire process. Then, we can eliminate option D because it focuses on just one step of the water cycle (evaporation) and does not encompass the full cycle. This leaves us with option B as the most comprehensive and accurate description of the water cycle.

2. Your answer is correct. Plants release water into the atmosphere through a process called transpiration. Transpiration is the movement of water vapor from plants into the air, primarily through small openings on the underside of leaves called stomata. Evaporation, on the other hand, refers to the process by which water changes from a liquid state to a vapor state at the surface of bodies of water or moist surfaces.

3. Your answer is correct. Balance in the water cycle means that the average annual precipitation over Earth equals the amount of water that evaporates. In other words, the water cycle is a continuous cycle where the amount of water that falls to Earth as precipitation (rain, snow, etc.) is approximately equal to the amount of water that evaporates from the Earth's surface and transpires from plants into the atmosphere.

To confirm this answer, we can examine the other options. Option B states that water that falls to Earth only enters oceans, which is not true as water also enters rivers, lakes, and groundwater. Option C is incorrect because the amount of water that falls to Earth does not necessarily have to weigh the same as the amount that condenses in clouds. Option D is also false because water that evaporates from Earth's surface does not remain forever in the atmosphere; it eventually condenses and falls back to the Earth as precipitation.

You're welcome.
