 Directions  1. Take out a piece of paper  2. From your textbook Chapter 6.1, write the headings and subsections of each section.  A. For each heading and subsection, write the words/sentences that are in bold.  3. Pick one figure from the section, draw the figure and write a description.  4. Write 2 sentences about what you expect to learn from this section.  Example: Chapter 6.1 Running Water  The Water Cycle  Water constantly moves among the oceans, the atmosphere, the solid Earth, and the biosphere. This unending circulation of Earth’s water supply is the water cycle.  Infiltration  Transpiration  Earth’s Water Balance  Balance in the water cycle means the average annual precipitation over Earth equals the amount of water that evaporates.  The ability of a stream to erode and transport materials depends largely on its velocity.  Gradient  Channel Characteristics  Stream channel

 With the Earth’s water constantly moving among the oceans, the atmosphere, the solid Earth, and the biosphere, why doesn’t the ocean level change drastically?

Annual precipitation over Earth = Amount of water that evaporates This is true for over the Earth as a whole. In different areas, there is not this same balance. Ex: Over land, there is more precipitation than evaporation, but over the ocean, evaporation exceeds precipitation.

 The ability of a stream to erode and transport materials depends largely on its velocity.  Velocity is the distance that water travels in a period of time. Some rivers flow fast such as 15 mph and some rivers flow slowly such as less than 1 mph.  The higher the velocity, the more sediment that the water can transport.

 Gradient is the slope or steepness of a stream channel.  Streams are not perfectly flat. They slope and are steep in different areas.

 In two sentences, summarize what you have learned from Section 6.1.
