What is the cause of the 24 hour day on earth?

The 24-hour day on Earth is primarily caused by the planet's rotation on its axis. As Earth rotates, different parts of the planet are exposed to sunlight, creating day and night. This rotation period has been relatively consistent over time, leading to the establishment of a 24-hour day.

What is the home planet and covered by land and water?

It's Earth... & now one more planet has been found out which is called as second earth, ie; Clepper

What are some of the ecological conditions that are necessary for human life to continue on Earth?

Living things obviously need water to survive they also need food to have energy. Air is another main thing, not all living organisms need oxygen though. Homeostasis. The ability to maintain homeostasis, equilibrium in the inner processes of an organism, is vital to the perpetuation of life.

How many planets does Earth's moon have?

Earth's Moon has no planets, unless you consider Earth to be the Moon's planet.

 

A planet is defined as an object revolving around the Sun that is large enough to form itself into a sphere from the force of gravity, and yet not be so large as to create fusion like the Sun.  It also must clear its orbit of other dust and debris.  A moon, on the other hand, is an object that revolves around a planet.

What parts of the earth are the coolest and why?

The poles, specifically the Arctic and Antarctic regions, are the coolest parts of the Earth. This is because these regions receive less direct sunlight due to the tilt of the Earth's axis and have a higher albedo, reflecting more sunlight back into space. Additionally, cold air sinks at the poles, leading to lower temperatures.

How long does it take to get to the moon and back in moon days?

It takes approximately 4 days to travel to the moon and back using current spacecraft technology, regardless of moon days. A moon day is the same as its orbital period, about 29.5 Earth days, and does not affect the travel time to and from the moon.

What are people who save the earth called?

There are no specific names. I'd recommend a Savior is someone who saves the Earth.

What makes a better model of the earth an apple or a peach?

An apple would make a better model of the Earth than a peach, as the apple's round shape more closely resembles the shape of the Earth. Additionally, apples are often used to represent celestial bodies due to their symmetry and size, making them a more suitable choice for representing the Earth in scale models.

Why is the temperature on the other planets different to the one on earth?

Depending on how far away from the Sun the different planets are the different the tempratures are. If a planet is really close to the sun (i.e. Mercury, Venus.) then they are going to be very warm. If planets are very far away from the sun (i.e. Mars, Jupiter, Saturn, Uranus, Neptune.) then they are going to be very cold. Earth Is in an area in the solar system called the 'Goldilocks zone'. It means that earth is in just the right place for life to exsit. Temprature wise it means Earth is niether to cold nor to hot so we are just right.

Hope this helps.

What is the second nearest sun from earth?

The closest planet to the Sun is Mercury. This is followed by Venus, then Earth.

How long ago did the Earth's rotation only take six hours?

Around 1.4 billion years ago, the Earth's rotation was faster, with a day lasting only around 6 hours. Due to gravitational forces, the rotation has gradually slowed down over millions of years.

Why was there life on earth but no life on venus?

Because Venus doesn't have oxygen. It's atmosphere is not as good as Earth's, instead of oxygen, Venus contains greenhouse gasses, carbon dioxide, and sulfur dioxide. The atmosphere on Venus is quite thick and because it is carbon instead of oxygen life can't exist on this planet including us humans, because in order to live you need oxygen. And without oxygen life cannot live on Venus. So the atmosphere is nothing like ours.

How does earth sustain life while other planets do not?

Earth can sustain life because it is in the "Goldilocks zone" of our solar system, meaning it has the right conditions for liquid water to exist. It also has a protective atmosphere that shields us from harmful space radiation and maintains a stable climate. Additionally, Earth has a diverse range of ecosystems that support a variety of life forms.

What are 4 global trends that indicate the health of planet earth is suffering?

  1. Rising global temperatures leading to climate change and extreme weather events.
  2. Decline in biodiversity and species extinction rates.
  3. Accelerating deforestation and habitat loss.
  4. Increase in pollution levels, particularly air and water pollution.

Which planet is nearer to the earth planet?

Venus is the planet closest to Earth in terms of distance. It is often referred to as Earth's "sister planet" because of their similar size and composition.

What is an another name for earth?

Tellus

Terra

La Monde

Soil

Pachamama

Are some.

Is earth 5th largest planet?

Earth is the fifth largest planet. Jupiter, Saturn, Uranus, and Neptune are all larger than earth in diameter and mass.

What is the distanse of puppis constellation away from earth?

Any constellation is a group of stars that appear to form some kind of pattern,

but have no connection with each other. They all happen to be in roughly the

same direction from us, but they're all at different distances. So there's no

such thing as a constellation's distance from us.

How are almost all organisms on planet earth dependent on the process of photosynthesis?

Because, by the process of photosynthesis plants produce oxygen which is most essential for humans, AND the plants provide food for their own survival and growth, and thus provide a food source for humans and many vegetation eating animals which are another food source for human life.

How long does it take the earth to make one rotation round the sun?

It takes approximately 365.25 days for Earth to make one full rotation around the Sun, which we refer to as a year. This is the basis for our calendar system.

How many degrees is the earth's axis tilted from the line that is perpendicular to the earth's plane of orbit around the sun?

The Earth's axis is tilted at an angle of approximately 23.5 degrees from the line perpendicular to the Earth's plane of orbit around the Sun. This tilt is the reason for the changing seasons on Earth as different regions receive varying amounts of sunlight throughout the year.

Is Earth the biggest planet closest to the sun?

No, Earth is the third planet from the sun. The biggest planet in our solar system is Jupiter.

How many people would it take to make a chain around the world?

Well, if you make the chain around the equator and assume one meter per person, you would need about 40,075,000 people... and a whole lot of boats.

Are we technically living in space since earth is a planet?

Yes, technically we are living in space since Earth is a planet that exists in outer space. Space is the vast expanse that exists beyond Earth's atmosphere, where celestial bodies like planets, stars, and galaxies are located. So, living on Earth means we are residing in the vastness of space.
