Sea level or Mount Everest, which can see the curved surface of the Earth?

Now we basically know that the earth is a circle, and we live in a sphere, not a square world. But this was very incomprehensible to many ancient people. In ancient times, due to the lack of development of science and technology, and the limitations of many thoughts, many of the perceptions about the shape of the home we live in are wrong.

It was not until the Middle Ages, due to the development of some Western navigation, that the outline of our entire earth was seen. At that time, people did not understand that the earth was a circle, so they sailed to many places, and eventually returned to the beginning. As a result, people are more convinced that the earth is round, not square.

The Earth is a sphere that is now a common understandingSo which angle can we better see that the earth is a curved surface from Mount Everest and at sea level? The answer, of course, is that you can better see the curved surface of the earth at sea level. Because when we are at sea level, we can see a very clear curve of the sea surface.

And this curved arc is still very large, it is precisely because in ancient times, navigators saw such a sea level, so we can further explore the mystery of this earth. <>

So why can't you see the curved surface of the earth well on Mount Everest? This is because although the peak of Mount Everest is very high, the ground is uneven, and there are some mountains next to the highest peak, which are actually very obstructive to the view. And the height above Mount Everest is very high, our vision will be limited by the clouds above, and it is impossible to see a complete spherical surface of the earth.

But on the ocean, there is no shelter and is closest to the earth's surface. The shape of water can be naturally presented with the shape of the earth, which is the clearest view of the curved surface of the earth.

I think you can only see the curved surface of the earth at sea level, and the Everest summit affects everyone's field of vision.

On Mount Everest, it is easier to see the curved surface of the earth. Because Mount Everest is the highest point in the world, and you can't see far away from the highest point, you can know that the earth is round.

We can see the curved shape of the earth through the sea level, because when we look out at the sea in the distance, we will see that there is a line in the distance. Many times some ships are slowly emerging from this line, which is due to the fact that the shape of the earth is a circle.

Answer A Compared with sea level at the same latitude, the angular velocity of rotation is equal; Due to the increase of the radius, the speed of the rotation line increases; The top of the mountain is shivering and serves the sunrise early and the sunset late, so the day is slightly longer, and the night is slightly shorter. Dong Zheng.

Answer] AD Answer Analysis] This question examines the comparison of the earth's rotation speed and its geographical significance, and the influence of the earth's shape on the length of the day. Because the earth is a non-luminous and opaque sphere, the sun can only illuminate one side of the earth, resulting in the phenomenon of day and night. Because Mount Everest is higher above sea level at the same latitude, the sunrise is seen earlier than the same latitude, and the sunset is later than the same latitude.

Therefore, the daylight hours are longer than those at the same latitude. Because the summit of Mount Everest is far from the center of the earth, the linear velocity of rotation is greater than that of sea level at the same latitude. So choose the AD option for this question.
