Planet Water

What was one major cause of the Aral Sea’s dramatic decline in water volume?

• Increased rainfall in the region

• Overuse of water for large-scale irrigation projects

• Climate change increasing the lake’s evaporation

• A natural decline in river inflows

What were the consequences of diverting the rivers Amu Darya and Syr Darya for irrigation purposes?

• The Aral Sea’s water levels increased

• The sea maintained its water levels despite human activity

• The sea’s water levels dropped drastically, leading to ecological and economic damage

• The rivers provided fresh water to surrounding countries, improving agriculture

How could using a shower head equipped with a diffuser help conserve water during a shower?

• It increases the flow of water, allowing for faster showers

• It mixes air with water, reducing the overall amount of water used

• It makes the water hotter, reducing the need to run it longer

• It collects water for reuse later in the shower

"Fossil water" is found in large underground aquifers that have been undisturbed for thousands of years.

What is a major risk associated with using non-renewable fossil water aquifers?

• These aquifers refill quickly and can be used indefinitely

• Once emptied, these aquifers will not refill in the foreseeable future

• They are less efficient at providing clean drinking water

• Fossil water is easily contaminated by surface water

What is one similarity between the situation in the Aral Sea and the concept of fossil aquifers?

• Both are examples of renewable water sources that replenish naturally over time

• Both involve non-renewable resources that are depleted when overused for human activities

• Both are found in regions with abundant rainfall and water resources

• Both serve as examples of successful water management

In the natural water cycle, what happens to water after it evaporates from a large body of water like the Aral Sea?

• It immediately returns to the body of water as rain

• It forms clouds and may precipitate elsewhere as rain or snow

• It falls as rain back into the sea only during the summer

• It becomes part of the groundwater system

Which of the following best describes what happened to the Aral Sea due to the overuse of water from its rivers?

• It remained one of the largest lakes in the world

• Its water levels increased due to improved irrigation techniques

• Its water levels decreased, leaving behind exposed lakebeds and ecological damage

• Its volume stayed stable, but the salt content increased

What happens to water when it changes from a gas to a liquid in the atmosphere?

• It evaporates, turning into water vapor

• It condenses to form clouds

• It freezes to form ice crystals

• It absorbs heat from the sun

Why is boiling water before drinking it an effective way to make it safe?

• It removes all minerals

• It kills harmful microorganisms

• It improves the taste

• It reduces the water's acidity

Which of the following diseases is NOT transmitted through contaminated water?

• Cholera

• Typhoid fever

• Tuberculosis

• Giardiasis
