Q:

How can you make a 3D model of the water cycle?

A:

A 3D model of the water cycle can be easily made using ordinary household items and the sun's warming power. To make the model, create a closed system where evaporation and condensation may be observed.

The requirements are simple. Begin with a bowl and a piece of plastic wrap. The first jar or bowl is filled to about a quarter's height with water. A rock or coffee mug is then placed inside. The plastic wrap is then placed on top, and the bowl is taped shut.

Placed in the sun, the water will first evaporate and then condense, eventually becoming liquid droplets that will "rain" down. A few drops of food coloring added to the water can enhance the visual effect.

  • Q:

    What is the water cycle?

    A:

    The water cycle, also known as the hydrologic cycle, describes the process of how water moves through Earth's environment. In general, water evaporates from oceans, then it condenses in the atmosphere as water vapor cools. When enough water gathers in clouds, it precipitates back to the Earth's surface as rain, hail, snow or sleet.

  • Q:

    Why is the water cycle important to humans?

    A:

    The water cycle is vital to human life because it delivers fresh water all over the globe. Most of the water on Earth is located in the oceans, which are too salty for humans to use. The water cycle helps distribute fresh, usable water for human use.

  • Q:

    What is accumulation in the water cycle?

    A:

    Accumulation is the part of the water cycle in which water gathers in large quantities such as rivers, lakes, oceans, glaciers, ice caps and aquifers, according to the U.S. Geological Survey. After water accumulates, it evaporates back into the atmosphere to start the water cycle over again. Accumulation occurs after water precipitates out of the sky.

  • Q:

    What would happen if the water cycle stopped?

    A:

    If the water cycle were to stop, lakes, rivers and groundwater sources would dry up, glaciers would disappear and precipitation would stop falling. All freshwater resources would be negatively impacted, and life on Earth would completely cease.
