Answer: a. greatest at the equator and drops as you move farther north or south
Explanation: Biodiversity is not evenly distributed on Earth. Terrestrial biodiversity is normally greater near the equator, (is richest in the tropics) and it lowers as you move towards the poles.
Tropical forest biodiversity cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.
The first person to calculate the circumference of the Earth and coined the word "geography" was Eratosthenes. The man who successfully applied his scientific research to create an illustration of the first world map was Anaximander. The person who invented the globe and argued that the representation of the world as a flat, two-dimensional object was not accurate was Ptolemy. He developed the science of geography, although he was better known for his contributions to mathematics was Eratosthenes. The Greek-derived word "geography" means to describe the Earth is correct. China's greatest contribution to geography was the compass. This allowed you to find out which direction you were going extremely easy. The earliest world map ever found was carved on a Babylonian clay tablet that showed Earth as a flat, circular disk, this is correct. It was believed to be created in 6th century BCE. Ptolemy incorporated topography into his maps, which means that the mountain and valley surfaces would appear on the map. This is correct and is the birth or starting of the topological maps! This early group, the Greeks, were the first to use rational thought or logic while investigating the physical world. It is believed that the science of geography originated with each of the following groups except the British. The British are believed to have no contributions to the science of Geography.
