Planet Earth
Earth is the planet where we live. It is the third planet from the Sun and is currently the only known planet in the Universe that is able to support life.
2,824 Questions
How does earth change the earths surface?
What is the actual time of rotation of earth?
It's about 23 hours, 56 minutes, 4.091 seconds (23.93447 hours or 0.99726957 mean solar days)
How do you know that the sun is bigger than the earth and moon?
Scientists have measured the sizes of the sun, earth, and moon using various methods such as direct observation, mathematical calculations, and comparison of their gravitational effects on other objects. The sun's diameter is about 109 times larger than the earth's and about 400 times larger than the moon's, making it the largest body in our solar system.
What is one unique characteristic about earth?
the earth is in the perfect place in the milky way. if it was any closer to the sun the temperate would be too hot, and if it was any further from the sun it would freeze over.
Is there a moon which is bigger than the earth and if so what?
There are many moons. Also its possible that in the future we will find other planets that will have other moons so it is possible.
Why do you live in Earth not on other planets?
Because there is little drinkable/usable water or oxygen on other planets
Thanks,

I could also point out that I was born on Earth, and even if I wanted to live on another planet, I don't really have any way to get there. No interplanetary trips were available.
Would the centre of the earth melt a diamond?
No, the center of the Earth would not melt a diamond. Diamonds have a very high melting point of about 3,550°C (6,422°F), which is much higher than the estimated temperature of the Earth's core, which is about 5,700°C (10,300°F) to 9,000°C (16,000°F).
Why do some people feel it is inaccurate to say that the Sun rises and sets?
Some people feel it is inaccurate to say the Sun rises and sets because it implies that the Sun is moving around the Earth, when in reality, it is the Earth's rotation that causes this phenomenon. The Sun appears to rise and set due to the Earth's spin. Additionally, using phrases like "sunrise" and "sunset" are holdovers from a time when it was believed that the Earth was the center of the universe.
Why is the earth the only planet so far that exists of human life?
We human beings originated on the planet Earth and so far we have briefly visited the moon but have not established any permanent residence there, nor have we even visited any of the other planets (not in person, we have sent robotic probes).
Is there more heads or legs on the Earth?
well, since the average person has 2 legs and 1 head, i would say that there are more heads on earth
yes
answ2. YES, but. Accident is the wrong word, 'by chance' is a better one.
But the chance is not completely open.
If for example you put a lot of chlorine atoms and a lot of sodium atoms in a container, what would be the output? (Well, ignoring the vigour of the reaction for the moment.)
From a 'simple chance' point of view you would expect some NaCl, some Na2Cl5, Na3Cl6 and so on, for these combinations are all valid under simple chance.
But we both know that we'd only get NaCl. No fancy molecules.
For the nature of the elements concerned is such that they can only make the one style of molecule.
But this restriction is not so for carbon say, where we may have many organic compounds formed from O, C, and H. But with the same magic of electron bonds.
And whilst on the subject of Carbon, it was believed that it needed three Helium atoms coming together virtually simultaneously, to create an atom of carbon. And at an energy of 100 million K.* It was known that in the early phases of the beginning of the Big Bang, that due to its rapid expansion, there would not have been sufficient time to create the known carbon. As it quickly expanded it would cool equally quickly.
Later studies show that indeed such temperatures were available in the explosion of a super nova. Thus the C was created, and flung out into space as the nova spread.
* [note that at an atom or molecule level temperature is equivalent to particle velocity.]
BTW, Fred Hoyle who created the name Big Bang, was also a force in discovering the nucleosynthesis by which carbon could be made.
What is the Earth's present orbit?
It's an ellipse with an eccentricity of about 0.002, inclined about 7 degrees from the Sun's equator, with a semi-major axis of just over 1 AU.
What would happen if earth moved closer to the sun?
If Earth moved closer to the sun, the increase in temperature could lead to catastrophic effects such as the melting of polar ice caps, changes in weather patterns, and widespread ecological disruptions. It could also lead to a loss of habitable zones for many species, including humans.
How many km is the Earth's core?
The Earth's core is about 6,371 kilometers from the surface to its center. The outer core extends from about 2,890 km to 5,150 km below the Earth's surface, while the inner core extends from about 5,150 km to 6,371 km below the surface.
Why will the dip not be the same everywhere in the world?
The dip of the Earth's magnetic field varies because the field is not perfectly uniform and is influenced by the local geology of each region. Changes in the magnetic properties of the Earth's crust, as well as the distribution of magnetic minerals, can cause variations in the magnetic field strength and direction, resulting in different dip angles at different locations around the world.
What would happen if every human on earth jumped at the same time would it have an effect?
If every human on earth were to jump at the same time, the collective force generated would be extremely small compared to the size of the planet. It wouldn't have a noticeable effect on earth's position or orbit. The impact would be equivalent to a small earthquake.
What could not occur if the Earth was not tilted?
If the Earth was not tilted, we would not experience seasons as we do now. The angle of the Earth's axial tilt relative to its orbit around the sun is what causes the variation in temperature and daylight that we experience throughout the year. Without this tilt, the climate would be much more consistent across the entire planet.
The Average temperature is 14'C, the highest recorded is 57.8'C and the lowest recorded is -89.2'C.
Is the 'rate of change' of daylight highest during equinox?
Yes. Around the time of the summer or winter solstice, the variation in day lengths from day to day is small - by only a few seconds or so. After a solstice, heading towards the following Equinox, the rate of change gradually increases, up to around 4 minutes a day around the Equinox.
If you plotted the lengths of day in daylight hours versus day of year, it would look like a sine wave with a peak at the summer solstice and a trough at the winter solstice.
Why is the earth called 'blue planet?
Earth is called the "blue planet" because when viewed from space, the planet appears to be predominantly blue due to its abundant water bodies like oceans and seas. Water reflects sunlight and the Earth's atmosphere scatters sunlight in a way that makes the planet appear blue from outer space.
Is the earth they only planet you can live on?
As far as we know, Earth is the only planet in our solar system that can support human life. Scientists continue to search for planets outside our solar system, known as exoplanets, that may have conditions suitable for life. However, Earth remains the only known planet where humans can live comfortably without the use of specialized equipment.
What observation supports the belief that Earth is round?
Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere.
What do you think will happen to earth if the arrangement of planets will be reversed?
If the arrangement of planets were reversed, it would disrupt the gravitational balance in our solar system. This could potentially lead to chaotic orbits, collisions, and other catastrophic events that could drastically affect Earth, such as major changes in climate and extreme weather. It would likely result in significant destruction and potentially threaten life on our planet.
What are the names of planets on either side of the earth?
venus on the sun's side and mars on the other side that is far from the sun.
