What is the sun made of 1 point?

The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70\%) and helium (about 28\%). Carbon, nitrogen and oxygen make up 1.5\% and the other 0.5\% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.

What is the sun made up of Class 1?

Structure and Surface The Sun is made out of 91\% hydrogen and 8.9\% helium. By mass, the Sun is about 70\% hydrogen and 27\% helium. This mass is held together by gravitational interaction, and this produces immense pressure and temperatures at the core.

What is the sun * 1 point?

The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light, ultraviolet light, and infrared radiation. It is by far the most important source of energy for life on Earth.

What is sun made up of answer?

The sun is made up of two main elements, hydrogen and helium. Hydrogen makes up about 92\% of all of the atoms in the sun while helium makes up about 7.8\%. Oxygen, carbon, neon and nitrogen make up most of the remaining 0.2\%.

Which two elements make up the Sun?

Despite the controversy, everyone agrees on the basics: The sun consists mainly of hydrogen and helium, the two lightest elements. It generates energy at its center through nuclear reactions that convert hydrogen into helium.

What is the Colour of sun for Class 1?

Sun, which is in the centre of the solar system is brilliantly white coloured. We have learnt that the sun is a hot red mass. Due to the earth’s atmosphere, the sun appears in various colours like yellow, red and orange.

What is the sun made of for Class 3?

It is made of 92.1\% hydrogen gas and 7.8\% helium gas. All stars are huge balls of very hot gases. The heat and light of the Sun gives life to the Earth and the Earth would have no life at all without the energy it receives from the Sun.

How sun is formed?

The sun formed more than 4.5 billion years ago, when a cloud of dust and gas called a nebula collapsed under its own gravity. As it did, the cloud spun and flattened into a disk, with our sun forming at its center. The disk’s outskirts later accreted into our solar system, including Earth and the other planets.

What is the Sun made of for Class 3?

Is the Sun made of fire?

The Sun isn’t “made of fire”. It’s made mostly of hydrogen and helium. Its heat and light come from nuclear fusion, a very different process that doesn’t require oxygen. Ordinary fire is a chemical reaction; fusion merges hydrogen nuclei into helium, and produces much more energy.

What is the Sun mainly made of?

NASA / SDO / Seán Doran Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. But it’s the sun’s tiny concentration of heavier elements, which astronomers call metals, that controls its fate.

What gases is the Sun mostly made up of?

The sun is a huge sphere of hot gas primarily composed of hydrogen (74.9\%) and helium (23.8\%) and lesser quantities of other gases.

Which is the biggest Sun in the universe?

The largest identified star in the known universe is VY Canis Majoris, a hypergiant of the constellation Canis Major , calculated to be more than 1,540 times larger than the sun.

What does the Sun produce energy by?

The sun produces energy through nuclear fusion. The sun is a large ball of hydrogen and helium undergoing constant nuclear fusion, in which atoms of hydrogen combine to form helium and release a large quantity of energy.
