Why is the earth called a unique planet Class 6?
The earth is called a unique planet because: It is the only planet which has favorable conditions that support life.
It is neither too hot nor too cold.
It has water and air, which are very essential for our survival..
Why do we see only one side of the moon always for Class 6?
The Moon orbits Earth once every 27.3 days and spins on its axis once every 27.3 days. This means that although the Moon is rotating, it always keeps one face toward us. Known as “synchronous rotation,” this is why we only ever see the Moon’s nearside from Earth.
Why is Earth so special?
Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun’s rays. … The fact that Earth hosts not just life, but intelligent life, makes it doubly unique.
Why do we have life on Earth?
Because of Earth’s ideal distance from the Sun, it receives the perfect amount of heat and light to allow life to be created and to support it.
What is the universe answer?
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. … The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.
How does Earth support life?
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
Which is the nearest celestial body to Earth?
Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.
What is the universe comprised of?
The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Who is the nearest planet of sun?
MercuryZipping around the sun in only 88 days, Mercury is the closest planet to the sun, and it’s also the smallest, only a little bit larger than Earth’s moon.
How is universe formed?
Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
What is the universe answer for Class 6?
Answer: The universe is a collection of all planets, stars, galaxies, celestial bodies, gases, dust clouds, light, etc. It is considered as an endless space.
What are planets for Class 6?
A planet is a large celestial body that revolves around the sun in fixed orbits. Planets do not have any light of their own but reflect the light of the sun. Planets also do not twinkle like stars because they are much closer to us.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
Which planet is known as the Earth’s twin?
VenusVenus is Earth’s evil twin — and space agencies can no longer resist its pull. Once a water-rich Eden, the hellish planet could reveal how to find habitable worlds around distant stars.
What is the true shape of the earth?
While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape. Our planet is pudgier at the equator than at the poles by about 70,000 feet .
