As we all know, Earth is our indispensable home. So far, this is the only place in the solar system where people have settled. Many people know that the size of the Earth provides many beautiful landscapes around us. , but this is only part of the beautiful scenery, but from your own perspective, everyone only sees the interior of the earth and cannot see the exterior of the earth. The earth looks like this from the outer universe. from inside the earth and from outside the earth are two different beauties. Everyone knows that the earth is mainly made up of inland land and oceans, which make up 71% of the earth. Because the land is 2% of the earth, just us. look at the color of the earth.
One is dark blue, one is emerald green, one is light yellow, and one is milky white. The milky white is the clouds, the dark blue is of course the sea, and theemerald green and light yellow. are on earth. Grasslands and deserts, there are four seasons on earth, and the colors of each season are different. In spring, when everything on earth is recovering, there are very few clouds in summer, the color of the ocean becomes bluer. and bluer, and the clouds are becoming rarer, in autumn the ground is full of light green dead leaves on the building, in winter it is white, everywhere is white, we see the color of the clean earth, the color. orange dirt everywhere.
On April 12, 1961, former Soviet cosmonaut Yuri Gagarin became the first person on Earth to enter the universe. The spacecraft he took sent him into a 320-kilometer-high orbit and circled the Earth. He has the following description of the landscape of the gardens in the outer universe: The sky is very dark, but the earth is very dark and seems very bright. According to photos of the Earth taken by spaceshipspatiales and the scenes seen with their own eyes by astronauts in the universe, the Earth is indeed a dark blue star.
So why does Earth appear dark blue when viewed from the universe? Judging from the size of the Earth and the original land, the area of the Earth is 510 million square kilometers, and the ocean accounts for 71% of the area, which is 2.5 times the total land area. . Most people live in the Northern Hemisphere, which makes up two-thirds of the planet's land surface. But you know what? The total area of the Northern Hemisphere map is very large, but it accounts for 40% of the area of the Northern Hemisphere map, and the remaining 60% is oceans. The total area of the oceans in the eastern, eastern and western hemispheres is also larger than that of the land surface. These data show that oceans are active everywhere on Earth.
The average depth of the oceans of the Terre is close to 4,000 meters, and the accumulated water flow reaches 1.338 million cubic meters, accounting for 96.5% of the total water flow in the earth's hydrosphere. Unlike land, the ocean is a continuous whole, connected to every present ocean, creating a unified global present ocean, and the earth is like a ship floating on the sea. As the ocean is vast and continuous, water becomes gray and, seen from the universe, the Earth transforms into a beautiful dark blue star.
