Answer 1

The Sum is a big star and
huge, glowing sphere of  hotgas.

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.

The Moon is made from many of the same things that we find here onEarth. Scientists studied about 800 pounds of moon rocks brought back by the Apollo astronautics.

Moon are similar to three kinds of igneous rocks that are found here on Earth: basalt, anorthosites, and breccias.

It's pretty well-known that most clouds are white, while rain clouds are usually a darker shade of gray. That is, acloud gets thicker and denser as it gathers more water droplets and ice crystals — the thicker it gets, the more light it scatters, resulting in less light penetrating all the way through it.

When water becomes warm enough, it evaporates as vapor into the air. ... When water droplets grow heavy enough, gravity pulls them down as raindrops. If the air is cold enough, the ice crystals can remain frozen and grow large enough to fall as snow, sleet, freezing rain or hail.

Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.

The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. 

Sound is the sensation produced by stimulation of the organs of hearing by vibrations transmitted through the air or other medium.

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity.

Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements.Star shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.

Answer 2

sun is a star
small molecule made a sun
due to the core of sun is very hot it is due to high pressure
natural satellite of Earth
made of rock impact creatures&volcanos
it is a visible mass of condensed vapour
it rains as it has water vapour
where two clouds meets it form a tunder effect so that light is formed
it sounds due to tunder effect
the theory of relativity usevally encompasses two interelated theory by Albert einsten;special relativity,general relativity
star is a fixed luminous point in the night sky,w hich is large,remote incandicent body like sun
stars are big expoding balls of gas made of hydrogen,helium
