The International Date Line isn't a fixed line at all, but actually sort of follows the 180° longitude line, zigzagging its way through a bunch of small islands, territories and nations.

Latitude affects temperature. One of the primary factors affecting the unequal heating of the Earth's atmosphere is latitude. Latitude is the measurement of the distance of a location on the Earth from the equator. The further away from the equator that a location resides, the less sunlight that this location receives.

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO₃)₂. Dolomite is found in sedimentary basins worldwide.

At the equator, the length of 1^o of latitude is equal to 110.6 km (68.7 mi.) and at the poles, the length of 1^o of latitude is equal to 111.7 km (69.4 mi.). For our purposes, we assume the length of 1° of latitude is 111 km. Lines of longitude, also called meridians, run north - south.
