Why is Water So Important to Us?
Water is essential for life. We need it for drinking, cooking, and cleaning. It also helps plants grow, which provide food for us and animals.
What is the Water Cycle?
The water cycle is the process by which water moves around our planet. It starts when the sun heats up water in rivers, lakes, and oceans, causing it to evaporate into the air as water vapour. This water vapour cools and forms clouds, which eventually release the water as rain or snow, returning it to the ground.
How Water Interconnects the Lithosphere, Biosphere, and Atmosphere
Water connects different parts of the Earth. The lithosphere (land) depends on water for soil moisture, which helps plants grow in the biosphere (living things). The atmosphere (air) holds water vapour that comes from evaporation and precipitation, creating weather patterns that affect life on land.
Understanding Water Availability
Look carefully at Diagram B. It shows that while 71% of the Earth is covered in water, only 0.01% is easily accessible freshwater. Most of the Earth’s water is salty and found in oceans, while glaciers and ice caps hold a significant amount, making it difficult for us to use. This means we must manage our freshwater resources wisely. Access to clean water is vital for health, agriculture, and daily living.
My Daily Water Use Diary
a) Diary Entry:
- 7:00 AM: Brush teeth (using water)
- 7:30 AM: Shower (using a lot of water)
- 8:00 AM: Drink a glass of water with breakfast
- 12:30 PM: Drink water during lunch
- 5:00 PM: Wash hands after school (using water)
- 6:00 PM: Help wash dishes (using water)
- 9:00 PM: Fill a glass of water before bed
b) Comparison with Diagram A:
- Similarities: Both my diary and Diagram A show that we use water for drinking, cooking, and cleaning.
- Differences: My diary has more uses related to personal hygiene, while Diagram A may focus more on agricultural use.
c) How Water Gets to Your Tap:
Water comes from rivers, lakes, or underground sources. It is treated by water companies to make it safe for drinking. Then, it travels through pipes and arrives at your tap.
Water Scarcity
a) What is Water Scarcity?
Water scarcity means there is not enough freshwater available to meet the needs of people and nature. It can be caused by drought, pollution, or overuse of water resources. Many people struggle to find clean water for daily life.
b) Reasons for High Water Demand:
- Population growth increases the number of people needing water.
- Agriculture requires a lot of water to grow food.
- Climate change can lead to droughts, reducing water supply.
Life for Girls Like Aysha
a) Describe Aysha’s Life:
Girls like Aysha often live in regions with limited access to water. They have to walk long distances to fetch water for their families, which can be dangerous and tiring. This can take away time from school and play.
b) Time Spent Finding Water:
Aysha spends several hours each day collecting water, which can be exhausting. Sometimes, she has to leave very early in the morning to make sure there is enough time to return before school.
c) Impact on Education:
Because Aysha and other girls spend so much time collecting water, they often miss school. This affects their education and future opportunities, as they may not be able to learn and develop important skills.
Researching Water Scarcity
a) Areas with Water Scarcity:
Parts of Africa, the Middle East, and some regions in Asia face severe water scarcity. Countries like Yemen and Sudan struggle to find enough clean water for their populations.
b) Areas without Water Scarcity:
Countries like Canada, Norway, and Brazil have abundant freshwater resources. They have lakes, rivers, and rainfall that provide plenty of water for their citizens.
c) Reasons for Distribution Patterns:
- Geography: Some areas have more rainfall and rivers than others.
- Climate: Some regions are naturally dry, making water scarce.
- Infrastructure: Wealthier countries can build systems to manage and supply water effectively.
Renewable or Nonrenewable Resource?
I believe water is a renewable resource. This is because it is part of the water cycle, where it continuously moves through the environment. However, if we misuse or pollute it, we can make it scarce or unsafe.
Stretch and Challenge
a) Research Your Family’s Water Costs:
Find out how much your family pays for water each year and which water company supplies your home.
b) Company Services:
Visit the company’s website to see what services are included in your water bill. This might include water supply, sewage treatment, and maintenance of pipes.
c) Worth the Cost?
Think about whether you believe the services you receive are worth the cost. Consider how important water is for your daily life and if the company provides reliable service.
