Which Planet Is Known As Blue Planet – Nicknamed “The Blue Planet!” Can you guess what it is? If you said water, you said it right! It covers just over 70 percent of the Earth’s surface. However, most of the water on Earth’s surface is salty seawater—which certainly isn’t safe to drink. Blue Planet Earth is the only planet in the Solar System with oceans, rivers and lakes. It also has vast polar ice sheets and mountain glaciers. The sun’s heat forms water vapour, which makes up a significant portion of the atmosphere (the air around Earth), and some of this vapor condenses into water droplets, making clouds visible. Therefore Earth is also the only planet where water is known as ice, liquid water and water vapour. The oceans contain most of the world’s water, clouds consist of tiny droplets of liquid water.
How much of the Earth’s water is fresh water if it drops drinking salt water (97%)? Look at the top of the diagram to see. Now look at the bottom of the diagram. How much fresh water is stored in glaciers and ice caps? When you look at the big picture, it’s easy to see that usable fresh water is a valuable resource. Fresh water (3%) Total water Glaciers and ice caps (68.7%) Groundwater (30.1%) Drinking water Most of the water on Earth is salty seawater. Only a small part is fresh water, and much of it is either frozen or deep underground. permafrost (0.8%) fresh water surface water and air water (0.4%)

These macaque monkeys know about one of the most interesting features of water. It can be found on Earth in the form of liquid, solid and gas. Can you see the three states of matter in the picture? States of Matter These ice-capped macaques in a hot pool are experiencing all three phases of water at once. This is possible because ice forms easily in cold air, and water does not need to reach its boiling point for some of its molecules to escape and form water vapor.

Solid: When water freezes, the molecules move further away and form the shape of crystals. This is why water expands or expands when it freezes. H2o! H2o! This symbol means that a water molecule has two hydrogen atoms and one oxygen atom. Water molecules move at different speeds in different states of matter. Liquid: When ice melts, the crystals break up and the molecules mix together. The molecules are linked together but still moving. H2o! Solid: When water freezes, the molecules lock into an open structure, forming hexagonal ice crystals. The molecules separate further than they would be in the liquid phase, so water expands when it freezes. This means that ice is not as dense as water, so it floats. Liquid: When ice melts, the regular structure of the molecules in ice crystals collapses. Molecules come closer to each other, attracted by the electrical forces that hold them together. But they can still move, so water is liquid. Gas: The molecules in liquid water are always in motion. If water is heated, it gives more energy to the molecules, so they move faster. Eventually they can move fast enough to break free and burst into the air to form an invisible gas called water vapour. Gas: When water is heated, the molecules gain more energy and move faster. Eventually they can move fast enough to break free and form water vapor in the air.
There is only a certain amount of water on Earth. That’s why water is moved around the planet in a never-ending process called the water cycle. If you look at the diagram carefully, you will see that water can exist in all three states (liquid, solid and gas) as it moves between the oceans, the atmosphere and the land. Water freezes and falls as snow Water falls as rain Snow forms glaciers Wind carries clouds over land Water vapor rises from lakes Water vapor condenses into clouds as they cool the water cycle Water vapor rising from the oceans forms clouds which are carried over land by weather systems . Clouds scatter rain and snow, creating streams, rivers and glaciers that flow back into the ocean. Even water that enters the land eventually returns to the ocean. This sequence is called the water cycle. When water from the ocean evaporates it leaves behind its salt content to become pure and sweet water, but as it passes over land, minerals and other substances dissolve in the ocean. From there the cycle starts again. Water vapor rises from the sea Water enters the land Rivers and streams flow through the land Water flows into the sea from rivers and streams Groundwater returns to the sea
The water cycle moves water around the earth. But water – especially fresh water – is unevenly distributed around the planet. You can take running water at home or at school. However, in many places people have to bring their water from fresh sources. Not a drop of water is wasted in these places! Water is a life-giving resource. And the more you learn about it, the more you’ll understand why it’s important to protect it. Considerable progress has been made over the past decade to help people gain access to better water sources, according to a valuable joint WHO/UNICEF water monitoring programme. However, it is estimated that around 780 million people worldwide still do not have access to safe drinking water which is the basis for the prevention and control of water-borne diseases.

Neptune is the farthest planet from the Sun at an average distance of 4.50 billion kilometers or 30.1 AU. The planet is a gas giant and the fourth largest in the Solar System. Because of its great distance from Earth, much about the planet remains a mystery. However, there are some established facts about the blue giant, which we will describe below.
Review: David Attenborough’s ‘blue Planet Ii’
Voyager 2 remains the only spacecraft to fly close to Neptune. Voyager 2 reached Neptune in 1989 during its journey through the Solar System and produced some of the clearest pictures of the planet. The spacecraft was closest to the gas on August 25, 1989, about 3,000 kilometers from the planet’s north pole. The close flyby was also important in providing astronomers great insight into Neptune with Voyager 2, confirming the presence of a magnetic field around the planet that was similar to that around Uranus. The close encounter also showed that Neptune had more than one ring around the planet and also confirmed the existence of a giant rotating storm system known as “Neptune’s Great Dark Spot”, formerly a cloud. was considered. While transmitting information from Neptune, Voyager 2’s signals took 245 minutes to reach Earth. Further exploration of Neptune is due to begin in the middle of the 21st century.
Due to the extreme distance between Neptune and the Sun, the planet has the largest orbit of any planet in the Solar System. The complex, extremely elaborate orbit, at 5.43 kilometers per second, at Neptune’s relatively slow speed, causes the planet to complete one revolution around the Sun in an astonishing 165 Earth years. Neptune’s orbit around the Sun is on average 2,798.656 million miles, or 30.11 AU (astronomical units). However, due to the planet’s orbital eccentricity of 0.009456, this distance varies between 2,771 million miles, or 29.81 AU, and 2,821 million miles, or 30.33 AU.
The identity of the first person to discover Neptune has been a matter of controversy throughout the history of astronomy. Most astronomers believe that the existence of Neptune was established mathematically prior to his empirical discovery by Le Verrier in 1845 using a telescope. However, Galileo Galilei was the first to observe Neptune using a telescope in 1613 and later recorded his observations in his notes. However, Galileo Galilei’s ordinary telescope showed that the motion of Neptune was slow, and this caused the astronomer to mistake Neptune as a fixed blue star.
Neptune’s thermosphere lies between its exosphere and stratosphere. Despite being the farthest planet from the Sun in the Solar System, Neptune’s thermosphere has an unusual feature of high temperatures, reaching about 477°.

C. These temperatures are similar to those recorded on Venus, the second closest planet to the Solar System. There have been many theories trying to explain how the Sun generates heat on a planet, but none have been proven.
Neptune is not a likely contender for a planet that has a ring, with Saturn being the most famous planet with spectacular rings. However, Neptune has a ring system composed of five rings: Arago, Galle, LaSalle, Le Verrier and Adams, each named after astronomers who were instrumental in discovering the planet. Neptune’s ring system is
