Question

Earths temperature at around 33c warmer than it would otherwise be, allowing life on earth to exist

Answer 1

$\color{red}{ANSWER}$

The $\color{green}{greenhouse}$ $\color{green}{effect}$ is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).

The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around $\color{orange}{33°}$ Celsius warmer than it would otherwise be, allowing life on Earth to exist.
