Question on: JSS2 Basic science - Thermal energy IV

Radiation plays a crucial role in maintaining the Earth's temperature balance. For instance, the Sun emits radiation, which warms the Earth's surface. Some of this radiation is then absorbed by the Earth and re-emitted as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, preventing it from escaping into space and helping to keep the Earth warm enough to support life. However, human activities, such as burning fossil fuels, can increase the concentration of greenhouse gases, leading to an enhanced greenhouse effect and global warming.
