This document discusses how weather and climate can positively or negatively affect people. It provides examples of how climate allows for energy production through solar and wind power, enables diverse crop growth in tropical regions, and drives tourism to warm tropical islands and cold alpine areas. Negative impacts discussed include floods from heavy rain, droughts from lack of rain causing water shortages and crop failure, heat waves fueling wildfires, and extreme winds from storms like hurricanes and tornadoes that threaten lives and cause property damage. The key difference between hurricanes and tornadoes mentioned is that hurricanes occur in summer along coastal regions of the USA.
3. Positive Effects of Weather and
Climate on people
• Energy
• Farming
• Tourism
4. Energy
• Man can harness solar energy and wind
energy.
• Solar panels on the roofs of home will trap
solar energy and convert the energy into
electricity for heating water.
• In some countries, solar energy is used to
replace petrol.
• Wind is used to turn wind turbines to produce
electricity.
6. Farming
• Climate determines the amount and the type
of crops that can be grown.
• For example, in tropical climate, farmers are
able to grow more than one crop a year as
there is high temperature and high rainfall
throughout the year.
8. Tourism
• Tropical island with hot and sunny such as
Maldives attract tourists from countries
experiencing winter.
• Tourists from warmer countries like to visit
Switzerland to ski Swiss Alps.
11. Negative Effects of Weather and
Climate on people
• Too much water
• Too little water
• Extreme heat and cold
• Extreme winds
12. Too much water
• Extreme weather like prolonged heavy rain
can cause rivers to overflow their banks and
cause flood.
• Buildings, transportation networks and
farmlands are damaged.
• Houses may be swept away and lives may be
lost.
14. Too little water
• Droughts occur when there are prolonged and
abnormally dry periods of insufficient rainfall.
• Rivers, reservoirs and lakes may dry up.
• Crop failure may lead to famines.
• Eg: Sudan, Ethiopia and Somalia.
16. Extreme heat and cold
• Heat waves that occur in summer may cause
bushfires and kill lives and destroy farmlands.
• Cold waves are caused when frigid polar winds
blow into a certain regions. Temperature fall
drastically to below 0◦C. People who are not
properly protected may be vulnerable to
pneumonia, bronchitis and frost bite.
19. Extreme winds
• Severe storms such as hurricanes and
tornadoes generate strong winds that cause
deaths, injuries, crop and property
destruction.
• Tornadoes and Hurricanes occur every
summer in USA.
• Continuous heavy rainfall result in severe
flooding that cause greater damage.
22. Questions to ponder…
• Why do you think there is an increase in
hurricanes and tornadoes?
• What is the main difference between a
hurricane and a tornado?
