These things that are blue cover over 70 percent of the Earth’s surface. Right from the Arctic Ocean to the Pacific and the Indian Ocean, this beautiful planet has numerous, huge saltwater bodies besides a number of smaller, freshwater ones. While the top surface of the Earth is covered by water, the deeper crust is red-hot. This is the reason seas and oceans look blue. If you try clicking a picture in the deep waters, it will appear completely blue. While lights of all other wavelengths get effectively absorbed, the blue light gets reflected and re-emitted. Go deeper, and the oranges, yellow, and green will be taken away too. When you dive into a modest depth, red light will be turned away and things will start looking blue. These molecules easily absorb ultraviolet, infrared and red light. The oceans contain huge amounts of water and the water molecules in them absorb lights of varying wavelengths. Why do the oceans appear blue in color?ĭuring daytime, the oceans appear blue. This is another reason for Earth being called the blue planet. The atmosphere disperses this more efficiently when compared to the orange or red light (orange and red have longer wavelengths). But have you ever wondered why the sky is blue? Here is the explanation to this. The oceans reflect the light of the sky above, hence appear blue. While it is light blue in areas close to the landmass, blue is darker in the deeper oceans. The shade of the blue color, however, varies depending upon the depth of the seas and oceans. The oceans are blue, so is the atmosphere. While over 70% of Earth is water, only a small portion is covered by land. When you look from outer space, the Earth appears blue. These things that are blue have made life possible on Earth and their presence is the reason we call this planet ‘The Blue Planet’. More than 2/3 rd of the planet Earth is covered by oceans, seas, lakes, rivers, glaciers and other forms of water. Over half of the Earth’s surface is covered by water. It is a special planet because it has the precious life-supporting liquid, the water. Our Mother Earth looks blue, one of the brilliant colors found in nature.Īmong all the planets in our solar system, Earth is the only known planet so far to have supported life. Sun appears bright white while the moon, ashy grey. While Saturn appears yellow, Mars looks bright red. They also look unique when you see their satellite images, including their colors. However, each planet is different and has varied compositions of gases and other atmospheric elements. All the planets revolve around the Sun in their orbits, so does the Earth.
There are 8 planets in our solar system, among which Earth is also one.
