Consider the following statements regarding one of the major geochemic...
Statement 1: Precipitation near the equator falls as rain into the ocean.
This statement is correct. Near the equator, the climate is generally warm and humid. As warm, moist air rises, it cools and condenses, forming clouds. These clouds then produce heavy rainfall. Since the equator is surrounded by vast oceans, a significant portion of the precipitation falls directly into the ocean.
Statement 2: Water vapor is a greenhouse gas that helps regulate the temperature of the Earth's atmosphere.
This statement is also correct. Water vapor is the most abundant greenhouse gas in the Earth's atmosphere. It plays a crucial role in regulating the Earth's temperature through the greenhouse effect. Water vapor absorbs and re-emits heat radiated from the Earth's surface, trapping it in the atmosphere. This process helps to maintain the Earth's temperature within a suitable range for supporting life.
Statement 3: Globally, precipitation far exceeds evaporation.
This statement is incorrect. The water cycle involves the continuous movement of water between the Earth's surface, atmosphere, and back. Precipitation refers to the process of water falling from the atmosphere to the Earth's surface, while evaporation refers to the process of water changing from a liquid to a vapor and returning to the atmosphere.
Globally, evaporation and precipitation are generally balanced, forming a cycle. The amount of water evaporating from the Earth's surface is approximately equal to the amount of water returning as precipitation. Therefore, the statement that precipitation far exceeds evaporation is not accurate.
Conclusion:
Based on the analysis, the correct statements are:
1. Precipitation that falls near the equator is most likely to fall as rain into the ocean.
2. Water vapor is a greenhouse gas that helps to regulate the temperature of the Earth's atmosphere.

Consider the following statements regarding one of the major geochemic...
- Oceans cover around 70% of Earth’s surface, so most precipitation falls right back into the ocean and the cycle of evaporation and precipitation begins again.
- The presence of water vapor in the atmosphere is one of the things that makes Earth livable.
- Like carbon dioxide, water vapor traps heat in the atmosphere and helps keep surface air temperatures on Earth in a habitable range.
- Temperatures on planets without water vapor in the atmosphere, like Mars, stay as low as -100° C.
- Evaporation and precipitation are balanced over Earth's surface. In other words, if evaporation increases, precipitation also increases.
