Explanation of the Greenhouse Effect & Global Warming!
Earth is considered a Goldilocks planet. It's not too hot and it's not too cold. It's just right due to the greenhouse effect. A greenhouse has glass walls and a glass roof. Sun rays shine through a greenhouse and when
heat tries to escape, it gets trapped. This allows for an ideal warm environment
for plants to grow, like tomatoes or tropical flowers. The Earth’s atmosphere acts like a greenhouse,
making our planet warm enough for life. The greenhouse effect is a natural heating
process that occurs when certain gases in Earth’s atmosphere trap heat. This happens when radiation from the sun shines
down on the Earth’s surface and causes it to warm. Since heat rises, when the Earth surface starts
to cool at night, the warm air begins its journey towards space. The warm air reaches a barrier of greenhouse
gases. These gases keep the warm air from escaping
into space. There are many natural greenhouse gases but
the main contributors to the greenhouse effect are water vapor, carbon dioxide, and methane.
Without these gases, life on Earth would not
be possible. It would be too cold. If the greenhouse effect is too strong, Earth
could get too warm. That’s when global warming comes into play. Global warming is the average surface temperature
increase on Earth. Scientists believe the amount of carbon dioxide
in our atmosphere contributes to the overall warming of the planet. Humans and nature play a role in how much
CO2 enters our atmosphere. As the greenhouse gases trap heat from escaping
the Earth, average global temperatures can increase. This can lead to a variety of global impacts,
like glaciers melting and sea levels rising. Next time, we’ll discuss Natural Climate
