Earth's climate and weather can be a real puzzle!
Welcome to Climate4Kids, a blog where you can learn about how climate works, how weather works and many more wonders of planet earth.
The blue square represents all of the atmosphere.Where does carbon dioxide come from?
The black dot in the middle is the amount of carbon dioxide in the air.
Oh, and the amount of carbon dioxide that man is adding to the air? Well, that's the white dot in the middle of the black dot.
97% of the carbon dioxide in the air is produced by nature.
It can come from volcanoes, animals breathing and when something is on fire.Where does carbon dioxide go?
Candles produce more carbon dioxide than an electric light bulb producing the same amount of light. The electric light bulb itself does not produce carbon dioxide, but to produce the electricity, sometimes coal is burnt. So when your friends light candles and say they are helping the planet by not using electricity, they are right. Their candles are producing more carbon dioxide which helps the plants grow.
Most of the carbon dioxide in the air is used by plants. Plants grow because of carbon dioxide, water vapor and sunlight.Is carbon dioxide pollution?
No. Carbon dioxide is necessary for life to exist. Without carbon dioxide, there would be no life on Earth.Can carbon dioxide cause warming of the planet?
No scientist would describe carbon dioxide as a pollutant. To be a pollutant, it would have to be damaging to life on Earth, carbon dioxide is necessary and vital, for life to exist. Without carbon dioxide or water vapor (sometimes called greenhouse gases) in the air, the entire Earth would be a desert - no plants and no animals.
No. Like all gases in the air, they slow the rate of warming and they slow the rate of cooling of the planet.
Greenhouse gases reduce the temperature extremes. Like all gases and other particles in the air, carbon dioxide reduces the amount of light and heat from the Sun and reduces the amount of light and heat being lost to space.
Jungles have many more plants and plant species, because there is much more water and water vapor available.Which has more animals?
Deserts have very little rainfall so very few plants can grow.
Most animals live where there is food. Many animals eat the fruit and nuts that the jungle provides.Which has more greenhouse gases?
With so few plants and almost no water, very few animals can live in deserts.
Jungles have lots of water and water vapor and with the animals, produce lots of carbon dioxide.Which is hotter?
Deserts have almost no water or water vapor, and very few animals to help produce the carbon dioxide that all plants need.
Desert temperatures can be more than 50°C (122°F) during the day.Which is colder?
Jungle temperatures only rise to about 35°C (95°F) during the day.
Desert temperatures can fall below freezing 0°C (32°F) at night.
Jungle temperatures only fall to about 20°C (68°F) at night.
Which has the most extreme temperatures?
As seen above, deserts have the most extreme temperatures.
Why? because they have less greenhouse gas.
Greenhouse gases don't increase the temperature, they reduce the temperature extremes.
