The largest of the Latitude parallel circles is the equator. The largest Latitude, numerically, is 90 degrees North and South.
The vegetation in most environments is crucial as a food source for many animals in the area. Without it, many animals may starve, thus setting on a chain reaction of animal displacement.

Heating of the Earth due to the Sun's rays causes convection currents of air upwards. The warm air moves upwards, while cool air from nearby regions fills in the lower areas.
<span>Heating of the Earth can cause warm water currents that flow from hot areas like near the equator and tropical areas, while cold water currents flow from the arctic and antarctic regions and the temperate regions. </span>
