23. The water conservation strategy being used when a household uses eco-friendly cleaning products is C. limiting consumption.

24. The two farming practices that use water most efficiently are B. planting perennial crops and D. using drip irrigation.

25. El Niño affects climate by B. Warm waters move eastward, making coastal South America warmer.

26. The two situations described that are examples of a standards and measurements issue related to land reclamation are C. Vegetation introduced to a reclaimed site is an invasive species that isn't native to the area and D. Monitoring of water quality at a reclaimed site shows high levels of metals, like lead, in the water.

29. If the specific heat capacity of water were smaller than it is, it would affect oceans and climate by A. The oceans could absorb less heat, leading to greater swings in temperature on land.

31. Fresh water is a limited resource because B. Most water covering Earth is salt water.

32. To ensure that a beach nourishment project remains effective for as long as possible, C. Dredging should be done as close to the shore as possible.

34. The three ways mining for materials used in smart devices impacts the environment are A. increases soil erosion, B. degrades vegetation, and E. increases child labor.

35. A lack of access to safe, clean water affects communities by B. decrease in educational achievement.

36. The fall line is B. a tall, steep area where rivers form rapids and waterfalls.

23. The correct answer is C. limiting consumption. Eco-friendly cleaning products help reduce the amount of water consumed during household cleaning. These products are typically designed to require less water during use, thereby limiting the overall consumption of water.

24. The two farming practices that use water most efficiently are: B. planting perennial crops and D. using drip irrigation. Planting perennial crops allows for long-term water usage and reduces the need for constant planting and irrigation. Drip irrigation delivers water directly to the plant's roots, minimizing waste through evaporation or runoff.

25. The correct answer is B. Warm waters move eastward, making coastal South America warmer. El Niño is a climate phenomenon characterized by the warming of the central and eastern tropical Pacific Ocean. This warming affects the atmospheric conditions, leading to changes in weather patterns worldwide. Specifically, warm ocean waters move eastward, causing coastal South America to experience warmer temperatures.

26. The two situations described that are examples of a standards and measurements issue related to land reclamation are: C. Vegetation introduced to a reclaimed site is an invasive species that isn't native to the area and D. Monitoring of water quality at a reclaimed site shows high levels of metals, like lead, in the water. These situations highlight the challenges and potential issues in ensuring that land reclamation projects meet environmental standards, such as using appropriate vegetation and maintaining water quality.

29. The correct answer is A. The oceans could absorb less heat, leading to greater swings in temperature on land. Water's high specific heat capacity allows it to absorb and store large amounts of heat energy, regulating the temperature of surrounding areas. If the specific heat capacity of water were smaller, the oceans would be less effective at absorbing heat, leading to more extreme temperature fluctuations on land.

31. The correct answer is B. Most water covering Earth is salt water. Approximately 97% of the Earth's water is in the form of saltwater found in oceans, seas, and other saline sources. Only a small fraction, around 2.5%, is fresh water, and a significant portion of that is inaccessible or locked in ice caps and glaciers. This limited availability of fresh water makes it a valuable and finite resource.

32. The correct answer is A. Large, coarse grains of sand should be used. When implementing a beach nourishment project, using large, coarse grains of sand helps to make the replenished beach more resilient to erosion caused by waves and currents. Coarse sand particles are less prone to being washed away compared to finer particles.
