5 Unit 5 Lesson 1 What Is the Water Cycle?
Water on the Move Water moves between Earth’s surface and the atmosphere through a process called the water cycle. The sun provides the energy needed for water to move through the water cycle. Copyright © Houghton Mifflin Harcourt Publishing Company

7 Water on the Move Evaporation is the change from a liquid to a gas.
Unit 5 Lesson 1 What Is the Water Cycle? Water on the Move Evaporation is the change from a liquid to a gas. Sunlight heats up water particles near the ocean’s surface, causing water to evaporate. When water evaporates, it forms an invisible gas called water vapor. Copyright © Houghton Mifflin Harcourt Publishing Company

Water on the Move Water can also evaporate from plant leaves through a process called transpiration. Copyright © Houghton Mifflin Harcourt Publishing Company

9 Unit 5 Lesson 1 What Is the Water Cycle?
Water on the Move The atmosphere is the mixture of gases that surrounds Earth. Water vapor rises into the atmosphere. In the atmosphere, water vapor cools to form clouds. Copyright © Houghton Mifflin Harcourt Publishing Company

12 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down As water vapor rises into the atmosphere, it cools. When water vapor loses enough energy, it condenses to form liquid water. Condensation is the change of a gas into a liquid. Copyright © Houghton Mifflin Harcourt Publishing Company

13 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down Water vapor condenses around tiny particles of salt and dust in the atmosphere to form water droplets. Copyright © Houghton Mifflin Harcourt Publishing Company

14 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down When billions of droplets are close together, they form clouds. Clouds can contain liquid water, ice crystals or both. Copyright © Houghton Mifflin Harcourt Publishing Company

15 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down Clouds can form high in the sky or just above the ground in the form of fog. Copyright © Houghton Mifflin Harcourt Publishing Company

16 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down As water droplets and snow crystals grow inside clouds, they become too heavy and fall to Earth as precipitation. Precipitation is water that falls from clouds to Earth’s surface. Rain, snow, and hail are all forms of precipitation. Copyright © Houghton Mifflin Harcourt Publishing Company

18 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down Precipitation that falls into the oceans may quickly evaporate back into the atmosphere. Copyright © Houghton Mifflin Harcourt Publishing Company

19 Unit 5 Lesson 1 What Is the Water Cycle?
What Goes Up Comes Down Precipitation that falls on land may be temporarily stored, it may flow across the land, or it may be used by living things. Depending on where it falls, water from precipitation may move quickly or slowly through the water cycle. Copyright © Houghton Mifflin Harcourt Publishing Company

Where Does Water Go? How does precipitation get into the ground to become groundwater? Copyright © Houghton Mifflin Harcourt Publishing Company

23 Unit 5 Lesson 1 What Is the Water Cycle?
Where Does Water Go? When precipitation occurs, much of the water will not reenter the atmosphere right away. Some water will seep into the ground. Water that is stored underground is called groundwater. Groundwater can be found near the surface or very deep underground. Copyright © Houghton Mifflin Harcourt Publishing Company

24 Unit 5 Lesson 1 What Is the Water Cycle?
Where Does Water Go? Runoff is water that cannot soak into the ground and instead flows across Earth’s surface. Too much precipitation may cause runoff, which flows into streams, rivers, and lakes. Runoff may also flood low-lying areas. Copyright © Houghton Mifflin Harcourt Publishing Company

25 Unit 5 Lesson 1 What Is the Water Cycle?
Where Does Water Go? Precipitation that falls in cold places may become part of a glacier. A glacier is a large, slow-moving mass of ice. Copyright © Houghton Mifflin Harcourt Publishing Company

26 Unit 5 Lesson 1 What Is the Water Cycle?
Where Does Water Go? Water can be stored in glaciers for a very long time. Eventually, glaciers will met. Melting glaciers can increase the amount of runoff in a place. Copyright © Houghton Mifflin Harcourt Publishing Company

30 Unit 5 Lesson 1 What Is the Water Cycle?
A Precious Resource Fresh water can come from rivers, lakes, and aquifers. An aquifer is a body of rock that stores groundwater. Aquifers are huge, underground water reservoirs. Copyright © Houghton Mifflin Harcourt Publishing Company

31 Unit 5 Lesson 1 What Is the Water Cycle?
A Precious Resource The water in an aquifer can run low or be polluted by human activities. Precipitation adds water to aquifers in places called recharge areas. Copyright © Houghton Mifflin Harcourt Publishing Company
