Lesson 5

Objective: I can explain how
climate change impacts water
availability

of treating waste-water so that it can be
used for other purposes

Unit 2B Quizlet Vocabulary Study Set

Introduction to Water Scarcity

●Imagine reaching for
the LAST bottle of
clean water😱

.

●Millions face this
reality daily due to
limited access to safe
water.

●Climate change
worsens water
availability and
contamination.

Climate Change and the Water Cycle

●Climate change
causes severe
droughts in some
areas and floods in
others.

●Rising temperatures
increase evaporation
rates.

●More water vapor
leads to intense
rainfall and potential
flooding.

Multiple Choice

Which of the following will MOST likely be expected if climate change continues as it is right now?

• freshwater becoming abundant

• increased droughts and flooding

• temperatures remain stable around world

Consequences of Excessive Rainfall

●Heavy rainfall
increases runoff,
introducing pollutants.

●Contaminated water
sources harm human
health and
ecosystems.

●Reduced availability of
fresh water for drinking
and agriculture.

Multiple Choice

What is one major consequence of excessive rainfall??

• Decreased surface water evaporation rates

• Increased availability of fresh water for drinking

• Contamination of water sources due to runoff

The Global Water Crisis

●Over 750 million
people lack access to
clean drinking water.

●Poverty increases
vulnerability to climate
impacts like drought
and flooding.

●Innovation in water
access strategies is
crucial for change.

Israel's Water Scarcity Solutions

Drip irrigation technology conserves
water for agriculture.
●slowly drops water on plants’ roots

●75% of crops now use this efficient
irrigation method.

Israel faces
frequent
droughts due to
its desert
climate.

Multiple Choice

What is an innovative solution Israel implemented to address its water scarcity?

• Drip irrigation technology for agriculture

• Reducing their output of agricultural

• Importing water from neighboring countries

Wastewater Treatment Innovations

●Wastewater Reclamation:
Treating wastewater so it can
be used for other purposes.

●Israel treats wastewater (water
from toilets, showers, and
sinks) for agricultural use since
1985.

●By 2015, 86% of wastewater
was recycled.

●Stormwater collection systems
provide additional safe water
sources.

Multiple Choice

How has Israel utilized wastewater reclamation since 1985?

• It uses wastewater for drinking purposes

• It has stopped treating wastewater entirely

• It recycles wastewater for agricultural use

Desalination Efforts in Israel

●Droughts in the 1990s
led to a desalination
program.
○Desalination -
removal of salt
from seawater

●Five plants along the
Mediterranean coast
produce drinking water.

●90% of Israel's drinking
water expected from
desalination by 2030.

An aerial view of the world’s largest desalination plant at Hadera in Israel.

Desalination
plants can
provide fresh
water to countries
with arid
environments,
where there are
not enough
fresh-water
sources.

Multiple Choice

Florida is home to one of the largest desalination plants in the U.S. Which of the following BEST describes the purpose of this plant?

• removing salt and minerals from seawater to produce freshwater

• capturing water from the sea and then condensing the water for other uses

• dripping small amounts of water onto the roots of plants and trees

Water Conservation Strategies

Simple actions can save water at
home!
●In the bathroom: Turn off taps,
limit shower time.

●In the kitchen: Store cold water,
reuse cooking water.

●In the laundry room: Run washing
machine with full load only

●Outside: Water grass before
sunrise / after sunset; use leftover water from household tasks for plants

Multiple Choice

Which is the BEST suggestion to reduce water consumption at home?

• Prepare a bath as it does not use as much water as a shower

• Water plants and trees using conserved water from other household tasks

• Halt the spread of disease by scrapping unused food into the sink

Your Role in Water Conservation

●Water scarcity affects
everyone, even in water-rich
areas.

●Implementing conservation
strategies helps global water
availability.

●What will you do to conserve
water in your daily life?

Multiple Choice

Which BEST describes the relationship between climate change and water availability?

• Climate change improves water availability through better rainfall patterns

• Climate change exacerbates water scarcity and contamination issues

• Climate change only affects water temperature, not availability

Answer each question on the lesson assignment and submit
when completed.
