What are the consequences of Earth’s being spherical ( round ) ?
The fact that the earth is geoid directly affects the formation of landforms and the climate types seen on our planet. For example, the temperature drops gradually from the equator to the poles. The decrease in temperature at the poles caused the diversity of living things to be less in these regions. The coldest temperature ever measured at the poles is -93.2. Day and night formation is another result of the earth being geoid. While it is night in the Northern Hemisphere, it is experienced during the day in the Southern Hemisphere. On September 23 and March 21, equality is experienced day and night. It is called “Autumn Equinox” and “Spring Equinox”.
The spherical shape of the earth causes different seasons in different regions in the same time period. In one hemisphere there is winter, in the other hemisphere there is summer. While the circumference of the equator is 40,076 kilometers, the circumference of the poles is 40,009 kilometers. However, the radius of the equator is 6378 km, and the radius of the poles is 6357 km. calculated as. The difference between the radii and circumference of the two regions is a result of the Earth being geoid.
