1a. Think about Earth’s hydrosphere and the sources of water on Earth. Use the diagram to help you answer the question. Which series shows Earth’s sources of water from largest to smallest?

• Lakes and rivers → Polar ice caps and glaciers → Oceans → Groundwater
• Groundwater → Polar ice caps and glaciers → Lakes and rivers → Oceans
• Oceans → Polar ice caps and glaciers → Groundwater → Lakes and rivers
• Oceans → Lakes and rivers → Groundwater → Polar ice caps and glaciers

1b. Use your selection in Question 1a to compare salt water and fresh water on Earth. Which type does Earth have more of?

• Fresh water
• Salt water
• Earth has equal amount of both
• Earth has no water

1c. Earth's salt water is found in which bodies of water? Select THREE answers.

• Oceans
• Seas
• Bays
• Lakes
• Rivers

1d. Earth's fresh water is found in which bodies of water? Select FOUR answers.

• Lakes
• Rivers
• Ice caps/Glaciers
• Groundwater
• Oceans

Fresh water is an important resource for the rice fields and people of Bali. Bali receives about 200 centimeters of precipitation each year. The data table below shows what happens to that precipitation. 2a. Think about what can happen to precipitation that reaches the ground on Bali. Which answer is BEST to fill in the blank?

• Enters ocean
• Goes into Mount Batur
• Becomes groundwater
• Becomes a cloud

2b. Use the table below to answer the following questions. How much precipitation on Bali will become water vapor in the atmosphere?

• 15 cm
• 110 cm
• 75 cm
• None of the above

2c. As more people visit Bali, they use more and more fresh water. To meet this demand (need), Balinese cities use groundwater. On Bali, when fresh groundwater is removed, salt water from the ocean can take its place. When salt water seeps into the ground, which two of Earth's systems do you think will be impacted FIRST?

• Hydrosphere
• Atmoshpere
• Geosphere
• Biosphere

Use the climate connections chart to answer this question. A warmer atmosphere due to increases in greenhouse gases leads to warmer oceans. What does having warmer oceans lead to? Select three correct responses.

• Melting snow and ice
• Stronger storms
• Rising sea levels
• Changing seasonal patterns
• More evaporation

A drought causes the farmers crops to die. Which of Earth's systems are interacting in the statement above. Select TWO answers.

• Atmosphere
• Geosphere
• Biosphere
• Hydrosphere

Wind blows away the loose soil. Which of Earth's systems are interacting in the statement above. Select TWO answers.

• Hydrosphere
• Atmosphere
• Biosphere
• Geosphere
