Biology - CORRECT ANSWER B. The Organization of Life The Water Cycle Read the following excerpt from Wikipedia: The water cycle involves the exchange of energy, which leads to temperature changes. For instance, when water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate. The evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It is also involved in reshaping the geological features of the Earth, through processes including erosion and sedimentation. The water cycle is also essential for the maintenance of most life and ecosystems on the planet. The water cycle is responsible for: A. Erosion B. Evaporation C. Transporting minerals D. Maintenance of life and ecosystems E. All of the above - CORRECT ANSWER E. All of the above Seasons on Earth are caused by: A. Proximity to the equator B. Zeus C. Gravitational pull of the moon D.

By burning the Earth's store of carbon, mankind is able to create the energy needed to operate our communities. However, we must be careful as we do so. By releasing more carbon into the atmosphere than is being locked up, we risk causing damage to the delicate carbon cycle." The Carbon Cycle. (2013). Geography for kids, The study of our Earth.
