Lesson 1 Assignment - Water Distribution on Earth

1. a covering of ice over a large area such as in the polar regions

• glacier
• groundwater
• ice caps
• reservoir
• storage

2. a large sheet of ice that moves slowly across the land

• glacier
• groundwater
• ice caps
• reservoir
• storage

3. an artificial lake built for storage of water

• glacier
• groundwater
• ice caps
• reservoir
• storage

4. the process of water being stored on Earth's surface in the ground or as a water feature

• glacier
• groundwater
• ice caps
• reservoir
• storage

5. water stored in the cracks and spaces between particles of soil and underground rocks

• glacier
• groundwater
• ice caps
• reservoir
• storage

6. Choose the answer that best explains one reason why conservation of freshwater is important.

• Freshwater should be conserved because it is limited to Earth's groundwater.
• Freshwater should be conserved because it can be found in large quantities on Earth.
• Freshwater should be conserved because it is limited to Earth's oceans.
• Freshwater should be conserved because it is the only water that can be consumed by humans.

7. Less than 1 percent of Earth's freshwater is readily available for human and animal use. Where is the majority of the remaining freshwater located?

• in ice caps and glaciers
• in the atmosphere
• in the oceans
• in lakes and rivers

8. Lakes and rivers are part of the _______________.

• hydrosphere
• geosphere

9. Based on the graph below, what can you conclude about the water on Earth?

• 97.4 percent of the water on Earth is saltwater
• 10 percent of the water on Earth is freshwater
• 55 percent of the water on Earth is saltwater
• 97.4 percent of the water on Earth is freshwater

10. Based on the table, what can you conclude about the percentage of ground ice and permafrost?

• The percentage of ground ice and permafrost is the same as groundwater.
• The percentage of ground ice and permafrost is greater than any other source.
• The percentage of ground ice and permafrost is less than any other source.
• The percentage of ground ice and permafrost is the same as lakes and rivers.
