Gases in the atmosphere like carbon dioxide, methane and water vapour trap some of the heat from the sun's rays, which would otherwise go back out into space. This keeps the Earth at a comfortable temperature, and prevents it getting too cold – like a giant greenhouse.
Also to know is, what is the importance of star to us?
The reason why stars are so important is because they have helped humans navigate through Earth . When it was dark these stars would light up the sky giving people light . In addition stars are very important because they make life on Earth.
Furthermore, where does the sky begin? troposphere
Similarly, you may ask, why the sky is high?
The bent Old Woman glared at the Sky and scrubbed the splodgy raindrop away. But then another raindrop fell, and another, till her swept and scrubbed front step was blotchy with raindrops. This was more than the bent Old Woman could bear. So that is why the Sky is so high.
Do stars have a purpose?
As for their purpose, stars are vital for life to exist. As we know, the Earth orbits the Sun at an ideal distance that caused life to thrive on its surface. The Sun's rays allow plants, algae and cyanobacteria to photosynthesise and store energy while also releasing oxygen into the atmosphere.

Do we need stars to live?
Stars keep themselves fueled. They fuse elements together to make new elements. While we can't make an actual star on Earth, some scientists are curious about creating this kind of reaction in the lab. In stars, hydrogen atoms fuse together to make helium.Why is it important to look at stars literally?
Astronomers and astrophysicists try to understand the universe and how things within it work by making observations and applying the science that we know to those observations. To date, over 850 extra-solar planets have been discovered, and it's thought that there may be billions of planets in the galaxy.What would happen without stars?
So, stars are like the furnaces which forge elements. Without them, there wouldn't be elements other than hydrogen and helium. Hence, the universe would be very cold and dark place, bathing itself with cosmic background radiation with no life forms to be seen anywhere.What is known as the North Star?
The North Star, or Polaris, is the brightest star in the constellation Ursa Minor, the little bear (also known as the Little Dipper).Why is it important to study space?
Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras. There's also medical research happening in space right now that could cure diseases and prolong human lives, and these experiments can't be done on Earth.Why do scientists study stars?
By studying the cosmos beyond our own planet, we can understand where we came from, where we are going, and how physics works under conditions which are impossible to recreate on Earth. In astronomy, the Universe is our laboratory!Why do we classify stars?
Astronomers classify stars according to their physical characteristics. Characteristics used to classify stars include color, temperature, size, composition, and brightness. Stars vary in their chemical composition.Why is the sky so high Answers?

The sky is really a blanket of gas around the planet that we call the atmosphere. When planet earth formed, the atmosphere was very then and just made of hydrogen and helium. Then volcanoes started to form and pumped out other gases like carbon dioxide and water vapour (… or steam).How far are Earth's clouds?
Below that is the home of mid-level clouds, which generally occur between 6,000 and 25,000 feet. Finally, closest to Earth's surface are low clouds, which hover at or below 6,500 feet. Weather 101 From heat waves and hailstorms to typhoons and tornadoes, our planet's weather can be intense.Why was the old woman angry at the sky answer?
But the more she swept, the more the dust swirled around her. The sky began to choke with all the dust that the old woman was causing with her sweeping. This made the old woman very angry.What is distance between earth and sky?
Definition of astronomical unit.An AU is approximately 93 million miles (150 million km). It's approximately 8 light-minutes. More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km). Earth's orbit around the sun isn't a perfect circle.
