When solar and lunar eclipses occur, can everyone on earth see them?

An eclipse is not. If it is not located in the vast eclipse belt, people will not know that there is an eclipse, but will only see the normal sun, which means that the eclipse is a local phenomenon.

The eclipse is a wide-area phenomenon, as long as you can see the moon, so people in the night hemisphere of the earth can see it.

Total solar eclipse is a kind of solar eclipse, that is, an astronomical phenomenon in which the sun is completely blocked by the moon in some parts of the earth. Total solar eclipse can be divided into five stages: initial loss, food, food, light production and recovery.

Because the moon is smaller than the earth, only people in the umbra of the moon can see the total solar eclipse. Folk call this phenomenon "Tiangou Food Day". When a total solar eclipse occurs, the ionosphere in the upper atmosphere will change accordingly because the moon blocks solar radiation.

The last total solar eclipse in China occurred on July 22nd, 2009, and the next one will occur in the mountainous area of northern Tibet on March 20th, 2034, but it is basically no man's land. In addition, on September 2, 2035, another total solar eclipse occurred in northern China, lasting for 1 min 29 seconds.
