Unit 4 Lesson 1 The Water Cycle
Florida Benchmarks SC.6.E.7.2 Investigate and apply how the cycling of water between the atmosphere and hydrosphere has an effect on weather patterns and climate. SC.6.E.7.4 Differentiate and show interactions among the geosphere, hydrosphere, cryosphere, atmosphere, and biosphere. Copyright © Houghton Mifflin Harcourt Publishing Company 2

What Goes Up … What is the water cycle?
Unit 4 Lesson 1 The Water Cycle What Goes Up … What is the water cycle? Movement of water between the atmosphere, land, ocean, and living things make up the water cycle. Water and snow moves downward due to gravity. Water vapor moves upward. Copyright © Houghton Mifflin Harcourt Publishing Company 3

How does water change state?
Unit 4 Lesson 1 The Water Cycle How does water change state? Water on Earth is found as a liquid, solid, or gas. Water absorbs energy as it melts from solid to liquid. Water absorbs energy as it evaporates from liquid to gas. Copyright © Houghton Mifflin Harcourt Publishing Company 4

How does water change state?
Unit 4 Lesson 1 The Water Cycle How does water change state? Water releases energy when it condenses from gas to liquid or when it sublimates from solid to gas. Water releases energy as it freezes from liquid to solid or deposits from gas to solid. Copyright © Houghton Mifflin Harcourt Publishing Company 5

How does water reach the atmosphere?
Unit 4 Lesson 1 The Water Cycle How does water reach the atmosphere? Water reaches the atmosphere through evaporation, transpiration, and sublimation. Evaporation occurs when liquid water changes to water vapor. Most evaporation comes from Earth’s oceans. Copyright © Houghton Mifflin Harcourt Publishing Company 6

How does water reach the atmosphere?
Unit 4 Lesson 1 The Water Cycle How does water reach the atmosphere? Transpiration is the release of water vapor into the atmosphere by plants. Sublimation is when solid water changes directly to water vapor without first becoming a liquid. Sublimation can occur when dry air blows over ice or snow.

How does water reach the atmosphere?
Unit 4 Lesson 1 The Water Cycle How does water reach the atmosphere? Rank the letters A, B, and C according to the amount of water each releases into the atmosphere. Copyright © Houghton Mifflin Harcourt Publishing Company 8

What happens to water in the atmosphere?
Unit 4 Lesson 1 The Water Cycle What happens to water in the atmosphere? Condensation is the change of state from gas to liquid. Condensation can occur as clouds, fog, or mist, or on the ground as dew. Precipitation is any form of water that falls to Earth from clouds. Rain, snow, and hail are forms of precipitation.

How does water move on land and in the oceans?
Unit 4 Lesson 1 The Water Cycle How does water move on land and in the oceans? Water that flows over land and into streams and rivers is called runoff. Water seeps into the ground through infiltration. Water underground is called groundwater. Copyright © Houghton Mifflin Harcourt Publishing Company 10

How does water move on land and in the oceans?
Unit 4 Lesson 1 The Water Cycle How does water move on land and in the oceans? Glaciers flow downhill and sometimes flow into the ocean. Winds move ocean water on the surface long distances. Cold or salty water will sink in the ocean, forming deep ocean currents that move large amounts of water. Copyright © Houghton Mifflin Harcourt Publishing Company 11

Water Works What does the water cycle transport?
Unit 4 Lesson 1 The Water Cycle Water Works What does the water cycle transport? The water cycle moves energy and matter. Energy is transported by changes in state and by the movement of water from place to place. Matter is transported by the vast amounts of water that move all around the world.
