Washington DC Standards
DC.6.5. Weather and Climate: Broad Concept: Weather (in the short run) and climate (in the long run) involve the transfer of energy in and out of the atmosphere. As a basis for understanding this concept, students:
6.5.3. Explain that a great deal of heat energy is absorbed when water evaporates and is released when it condenses. Illustrate that this cycling of water and heat in and out of the atmosphere plays a critical role in climatic patterns.
DC.6.6. Resources: Broad Concept: Sources of materials differ in amounts, distribution, usefulness, and the time required for their formation. As a basis for understanding this concept, students:
6.6.1. Explain that fresh water is limited in supply and uneven in distribution; describe why it is essential for life as we know it and also for most human activities, including industrial processes.
6.6.2. Recognize that fresh water is a resource that can be depleted or polluted, making it unavailable or unsuitable for humans.
6.6.8. Explain the important role of the water cycle within a watershed.
