Answer 1

Here are the answers to your questions:

11. All of the following are ways in which WATER & ENERGY are interdependent EXCEPT....
Answer: water provides energy to livestock for drinking
(Drinking water does not represent a direct interdependency between water and energy in the context of energy production/usage.)

---

12. Agricultural runoff can be best described as...
Answer: the water that leaves crop fields and often carries pollutants into fresh water sources
(Agricultural runoff refers to rainwater or irrigation water that flows over fields and can carry fertilizers, pesticides, and other pollutants into nearby water sources.)

---

13. Why is rainwater harvesting important in sustainable farming practices? (Choose 2)
Answers:

1. It reduces the demand for using groundwater for irrigation
2. Allows water to be stored for future use
   (Rainwater harvesting is essential for conserving water and reducing the reliance on groundwater.)

---

14. Although about 70% of earth's surface is covered in water, about how much of that water is freshwater?
Answer: 2.5%
(Only a small fraction of the Earth's water is freshwater, most of which is trapped in glaciers and ice caps.)

---

15. The human race is using the freshwater from our groundwater aquifers faster than it can be replaced. This overuse can result in the following:
Answer: all of the above are impacts
(All mentioned impacts - the water table being lowered, the ground sinking, and salt water mixing into our freshwater supply - are consequences of aquifer overuse.)

---

16. One of the biggest impacts on the water cycle by global warming is....
Answer: the increased rate of evaporation
(Global warming leads to higher temperatures, which increases the rate of evaporation of water from oceans, rivers, and lakes into the atmosphere.)
