    1.The horizon is arc-shaped;

    2.Ships on the sea level always see the mast first and then the hull when they come from afar, proving that the earth is spherical;

    3.During a solar eclipse or lunar eclipse, observing the moon, the solar eclipse always has a certain arc. prove that the earth is round;

    4.Magellan's circumnavigation of the world;

    5.During a partial lunar eclipse, the Earth blocks a portion of the daylight, causing the Earth's shadow to be cast on the surface of the Moon, just like looking in a mirror to the Earth, allowing us to see the shape of the Earth's sphere.

    6.If the earth is flat and there is nothing in the way, then it should be the same far no matter how high you look, but in fact, no matter where you are on the earth, you will be looking far away. So the earth is round.

    Quite simply, the shape of the Earth can be seen in space, and it can be proved that the Earth is a spherical shape from all directions. Since we can now ascend to space, we can prove that the earth was round.

    The phenomenon of long nights and long days at the poles Aristotle concluded that the earth is a sphere based on the arc of the edge of the part of the lunar eclipse obscured by the earth's shadow.

    There are many phenomena in life that can indicate that the earth is a sphere, and the common ones are as follows:

    1. The most common one: the sun rises in the east and sets in the west, this phenomenon is enough to prove that the earth is a sphere.

    2. Sea level.

    The ships that come from afar, always see the mast first, and then the hull, which can also prove that the earth is a sphere;

    3. Standing high and seeing far away can show that the ground plane is an arc, and it can also show that the earth is a sphere;

    4. When a partial lunar eclipse occurs, the earth blocks part of the sunlight, so that the shadow of the earth is projected on the surface of the moon, just like looking in a mirror for the earth, so that we can see the shape of the earth's sphere, which can also show that the earth is a sphere.

    Magellanof the circumnavigation of the worldLunar eclipsePhenomena can prove that the earth is a sphere.

    Ancient Greece. Scholar Aristotle.

    According to the analysis of the lunar eclipse, the edge of the part of the moon that is obscured by the shadow of the earth is arc-shaped, so the earth is a sphere or an approximate sphere. Magellan also made a voyage to prove that the earth is a sphere.

    The development of awareness.

    Ancient times. According to the analysis of the lunar eclipse, the ancient Greek scholar Aristotle believed that the edge of the part of the moon that is obscured by the earth's shadow is arc-shaped, so the earth is a sphere or an approximate sphere. Magellan also made a voyage to prove that the earth is a sphere.

    Nowadays. Mankind has been exploring for a long time, and Magellan was the first to achieve a circumnavigation around the world, confirming that the earth is a sphere. With the development of human science and technology and the application of modern detection technology, people finally discovered that the earth is an irregular sphere with slightly flattened poles and slightly bulging equators.

    Astronomy experts say that the Earth is indeed not an authentic sphere and that it looks a little strange. The reason why the earth grows like this is because it not only revolves around the sun, but also rotates at the same time, and the surface of the earth has both land and water, and in order to maintain the internal gravitational balance, under the "fight" of all parties, it grows into this strange shape.

    Hello, 1.The horizon of the Earth is curved, which indicates that the Earth is a sphere. If the earth is flat, then its horizon should also be straight.

    2.The Earth's shadow takes on a curved shape during a lunar eclipse, also proving that the Earth is a sphere. During a lunar eclipse, the Earth is between the Sun and the Moon, which causes the Earth's shadow to be projected onto the Moon.

    Depending on the way the Moon shades the Earth, the Earth's shadow takes on a circular shape. 3.During the time of the Great Voyage, different constellations were observed in different places.

    This indicates that the curvature of the Earth has undergone a metamorphosis because when people stand in different places, their vision is affected by the curvature of the Earth. 4.The Earth's gravitational field also indicates that the Earth is a sphere.

    If the Earth is not spherical, then the Earth's gravitational field will also be different. 5.Satellite images of the Earth also prove that the Earth is a sphere.

    Satellite imagery shows the curved boundaries of the Earth and the tilt angle of the satellite**. These evidences suggest that the Earth is a sphere, not a flat Earth.

    Hello, there are several reasons why the earth is a sphere: first, the rotation of the earth produces a centrifugal force, which causes the equatorial part of the earth to protrude slightly outward from the pole part, thus forming a shape similar to an oblate sphere. This shape is known as "equatorial expansion".

    Secondly, the gravitational pull of the earth will cause the earth to reduce the surface energy as much as possible, and the sphere is the shape with the smallest surface energy, so the earth will eventually become a sphere. In addition, we can also prove that the Earth is a sphere by observing its curvature. On the Daqing Sea or on the flat ground, we can see distant objects gradually disappearing below the horizon, because the curvature of the earth makes them gradually disappear from our line of sight.

    In short, all of the above factors indicate that the Earth is a sphere, which is also the consensus of scientists on the shape of the Earth.
