Explanation:
The process in which water vapour and carbon dioxide
traps heat is called the “greenhouse effect”.
The greenhouse effect is a natural phenomenon which
occurs every day. To illustrate an example of this natural phenomenon, d<span>uring the day the Sun shines through the atmosphere.
Earth's surface warms up because of the sunlight. Meanwhile at night in the
absence of the sunlight, Earth's surface cools back and releasing the heat back
into the air. However some of the heat is retained by the greenhouse gases
(such as carbon dioxide and water vapour) in the atmosphere. This process what
keeps our planet Earth warm and cozy at an average temperature of 16°C.</span>
