What us an asrtonomical unit?
An astronomical unit (AU) is the average distance of the earth from the sun.
Why can the Moon appear as large as the Sun even though you know the Moon is much smaller than the Sun?
The Moon is much closer to Earth than the Sun is, therefore making the moon appear to be as large or larger than the sun when viewed from Earth.
How does the sun help the earth besides providing light?
The sun gives the Earth warmth and energy, without which it would be impossible for life to exist. Also, without the sun, it is unlikely that Earth would have ever formed, because it formed out of a disc of debris that circled the sun.
Why do stars seem to appear a sunrise?
The sun rises because of the position of the earth in relation to the sun. One complete revolution of the earth happens every 24 hours. While the earth is turning it seems that the sun is in a different spot in the sky, but the sun is stable and the earth is spinning.
Which movement represents a day when the earth moves around the sun?
The Earth's spin, or rotation on its axis gives us a day.
What does sun give us?
The Sun is a huge star that is seen during the day on Earth. It gives the Earth many things, it give energy, vitamins, heat and helps things live.
What is called the prime source of energy?
For us here on Earth, the prime source of energy is the Sun.
What would happen if the sun exploded and released a ton of oxygen into earth?
If the sun exploded it would not give us oxygen; it would simply vaporize Earth.
Where are the earth and sun located in space?
The Earth is right here (you are standing on it). The Sun is at a distance of 150 million kilometers from us. Earth moves around the Sun. Earth, Sun, and the other planets (i.e., the Solar System) move around the Milky Way, at a distance estimated at 26,000 light-years.
What makes you see the moon in the sky?
It is the reflection of the sun's light on the moon that makes it visible to us here on Earth.
How long would it take us on earth to know that the sun has burned out?
It would take about 8 minutes and 20 seconds for us here on Earth to realize that the sun has burned out. This is because light from the sun takes that amount of time to travel to us.
What does Earth give us about gardening and what can we give the Earth?
Earth provides us with the necessary soil, water, sunlight, and nutrients to support plant growth in gardening. In return, we can give back to the Earth by practicing sustainable gardening methods, such as composting, using natural fertilizers, and conserving water.
Do the moon and stars make us warm?
While the stars are suns and burn like our Sun, they are so far away that the heat they give off is not noticeable here on Earth. The moon does not give off heat, but merely reflects the sunlight which falls on it.
Does the moon reflect the light it received from the sun?
The Moon reflects PART of the light it receives from the Sun. And part of this reflected light is seen by us, here on Earth.
How does the radiation reach us here on earth?
If the Sun were larger or closer, the Earth would be too hot to be liveable. Or if it were weaker or farther away, the Earth would be completely frozen.
How does thermal energy give us heat?
it gives us energy beacause the energy come directly from the sun which comes towards the earth.
Why is the sun so important to us on earth?
The sun is so important to us on Earth because it provides us with light and heat. There would be no life on Earth if it wasn't for the sun. The Earth would be a big frozen rock.
