The phenomenon of day and night is caused by the Earth’s rotation on its axis…
The spherical shape of the Earth is always half illuminated by the Sun, thus giving birth to day and night, because the Earth rotates on its own axis, so every part of the Earth’s surface is illuminated by the sun in turn.
Explain the phenomenon of day and night on Earth.
The Earth is spherical in shape and rotates on its own axis from west to east, so at the same time, people standing at different meridians will see the Sun at different heights, points of different meridians will have different hours. each other, (local time or solar time).
For timekeeping and international transactions, the Earth’s surface is divided into 24 time zones, each 15 degrees of longitude. Time in zero zone will be taken as universal time or GMT (Greenwich Mean Time). Vietnam is in time zone number 7.
As the Earth rotates on its own axis, every place at different latitudes on the Earth’s surface (except the poles), has different long velocities and turns from west to east. Therefore, objects moving on the Earth’s surface will be deflected from their original direction.
