Study Guide Unit 9 - The Water Cycle
This unit addresses the movement of water through the crust, ocean, and atmosphere
#1 Students will recognize the significant role of water in earth processes.
Explain that a large portion of the Earth’s surface is water, consisting of oceans,
rivers, lakes, underground water, and ice.
Relate various atmospheric conditions to stages of the water cycle.
Describe the composition, location, and subsurface topography of the world’s oceans.
Explain the causes of waves, currents, and tides.
#2 Students will describe various sources of energy and with their uses and conservation.
Explain the role of the sun as the major source of energy and its relationship to wind and water energy.
Questions – students will be asked to answers these questions throughout the unit.
#1 How does the location of water on Earth's surface and the conditions of the atmosphere affect its path through stages of the water cycle?
#2 How does the amount of saltwater differ fromthe amount of freshwater on Earth?
#3 Does salt water and fresh water movethrough the same water cycle?
#4 Where does salt in the ocean come from?
#5 Why does water continually move through the water cycle?
