01 - The importance of water and its uses

Question 1

What is the Goldilocks zone?

Answer 1

Goldilocks zone means that it isn’t too wet and it isn’t too dry, the conditions are perfect for life to exist

Question 2

What are the three main ways that water helps create helpful thermal conditions on Earth?

Answer 2

• Oceans: moderate temperatures by absorbing heat, storing it and releasing it slowly.
• Clouds: made up of tiny water droplets and ice crystals reflect around a fifth of incoming solar radiation which lowers surface temperatures.
• Water vapour: (potent greenhouse gas) absorbs long-wave radiation from the Earth helping to maintain average global temperatures

Question 3

3 uses of water for people

Answer 3

• Sweating cools humans by encouraging evaporation on the skin
• Hydroelectric power generates energy through water movement.
• Drinking water and sewerage services are crucial to global health

Question 4

3 uses of water for Flora

Answer 4

• Crops are irrigated by water
• Transpiration releases water vapour into the atmosphere through the stomata of plants, which also helps to cool the plant.
• Water transports mineral nutrients in soil

Question 5

2 uses of water for Fauna

Answer 5

• Fur covered animals cool by evaporation by panting
• Water makes up 65-95% of all living organisms

Question 6

What are the three main ways in which water helps create helpful thermal conditions on Earth?

Answer 6

1. Oceans moderate temperatures by absorbing heat, storing it and releasing it slowly.
2. Clouds made up of tiny water droplets and ice crystals reflect around a fifth of incoming solar radiation which lowers surface temperatures.
3. Water vapour (potent greenhouse gas) absorbs long-wave radiation from the Earth helping to maintain average global temperatures almost 15oC higher than would be otherwise.

Question 7

What percentage of all living organisms is made up of water?

Answer 7

Water makes up 65-95% of all living organisms for both flora, fauna and people.

Question 8

What is the process of photosynthesis?

Answer 8

Photosynthesis combines CO2, sunlight and water to make glucose and starch.

Question 9

What happens to plants if they do not have water?

Answer 9

Water is required to maintain rigidity otherwise they wilt.

Question 10

How does sweating cools humans by encouraging evaporation on skin?

Answer 10

Sweating cools humans by encouraging evaporation on skin.

Question 11

What is the role of water in maintaining rigidity of plants?

Answer 11

Water is required to maintain rigidity of plants, otherwise they wilt.

Question 12

What is transpiration and its effect on plants?

Answer 12

Transpiration releases water into the atmosphere through evaporation and cools plants.

Question 13

What are the uses of water in food manufacturing, brewing, paper making and steel making?

Answer 13

Water is used in food manufacturing, brewing, paper making and steel making for various processes such as cleaning, cooking, and cooling.

Question 14

What is the role of water in mineral nutrient transport in soil?

Answer 14

Water transports mineral nutrients in soil, making them available to plants for growth and survival.

Question 15

What is the role of water in respiration?

Answer 15

Water is the medium for all chemical reactions in the body including the circulation of oxygen and nutrients, and plays a crucial role in the process of respiration.
