QUESTION 1



1.1



The greenhouse effect is a natural process that warms the Earth's surface. It occurs when the
sun's energy reaches the Earth in the form of sunlight, which is absorbed by the surface and
then radiated back into the atmosphere as heat. Some of this heat is trapped by gases in the
atmosphere known as greenhouse gases, which include carbon dioxide (CO2), methane
(CH4), water vapor (H2O), nitrous oxide (N2O), and ozone (O3). These gases allow sunlight
to enter the atmosphere but prevent the heat from escaping back into space. As a result, the
Earth's temperature rises, maintaining conditions suitable for life.
