A water footprint is a way of measuring the total volume of fresh water used by a nation, to produce the goods and services consumed by that nation. The water footprint includes the water content of goods imported into the country minus goods exported. Once, countries largely grew their own food, but an increasing number no longer do because they are running out of freshwater.
Humans that live in countries where water is scarce can now import virtual water. Virtual water is the amount of water used to grow food crops, raise livestock, or make other products that are exported out of that country. In other words, water scarce countries can now import high water consuming products, like rice and cotton, while exporting low water consuming products, like citrus fruits. Major water exporters include The United States, Canada, Austria, Argentina, and Thailand. Major importers of virtual water include Japan, Sri Lanka, Italy, South Korea, and the Netherlands.
There are serious environmental consequences to exporting this much water. The virtual water trade is emptying the Colorado River and the Rio Grande, which both now fail to reach the ocean for much of the year. Exporting water is sucking dry what was once the country's largest underground water reserve, the Ogallala aquifer beneath the high plains of the Midwest. The Ogallala is being depleted faster than it can be replenished by rain. The water is being shipped away. This water is being exported in the form of crops or livestock. It will enter a water cycle in another part of the world, never to replenish the Ogallala again!
1. Describe the problem: Exporting water is sucking dry the ocean.
2. Which process in the water cycle (condensation, precipitation, infiltration, runoff, evaporation, or transpiration) is being impacted? Explain how it is being impacted.
3. What can humans do to solve this problem?
Answers
Water is one of the most important things to you, and to all living things. The fact that you can measure the volume of room temperature water with a beaker is a clue that room temperature water is in liquid form. If you keep raising the temperature of that water, it will eventually begin to boil, bubbling up and releasing steam. The steam is an example of what? *
Answers
Answer:
steam is and example of vapor and gas.
Answer:
evaporation
Explanation:
because the water boils and steam leave so it's evaporation
How does a number line describe the location of an object?

SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend, Sandy, told him that he should try using Clean-O detergent, a new brand of laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants three times each, the pants washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water. 1) What was the problem SpongeBob wanted to investigate? 2) What was the problem SpongeBob wanted to investigate? 3) What is the dependent variable? 4) What should be SpongeBob’s conclusion?
Answers
Answer:
1) SpongeBob investigated whether Clean-O detergent is a good laundry soap. 3) the dependent variable is the color of the pants/how clean the pants were. 4) SpongeBob's conclusion should be that Clean-O detergent is not a good detergent.
