This is caused by the release of harmful gases like carbon dioxide (CO2), chlorofluorocarbons (CFCs) into the atmosphere.
The effect of global warming
- Rising sea level
- Increase in temperature
- Excessive flood.
The Weather Chart
The weather can change often in a day. These weather changes can be recorded in a chart. Such a chart is called a weather chart. In the next activity, you will make a weather chart.
Preparing a weather chart and Materials Required
Your science notebook
Weather-measuring instruments such as thermometer, wind vane, rain gauge and barometer.
Procedure
1. Observe the weather for one day.
2. Enter your findings into a table such as shown
Weather chart
