User: describe how the climate plants and animals change from the artic circle to the equator

Weegy: Bits and pieces of the earliest known land plants date back almost 500 million years to the Ordovician Period, and their fragmentary remains indicate the plants were related to liverworts that exist today, Gensel said. [ The earliest vascular plants -- ones with water-conducting tissues -- so far are known to date back about 425 million years. Sparsely branched, they were about an eighth of an inch tall and grew a few reproductive bodies known as sporangia on their branches. By contrast, the new plants, which lived only a few million years later, would have stood four or more inches tall, bore many branches with dense rows of sporangia and probably grew in clusters, she said. They more closely resembled much younger early Devonian plants from about 390 million years ago than any other Silurian forms. ]

As you move from the Arctic Circle to the Equator, the climate becomes warmer, and there is more sunlight and rainfall. Plants change from small shrubs and mosses in the Arctic to dense forests and tropical vegetation near the Equator. Animals also change—from cold-adapted species like polar bears and arctic foxes to warm-climate animals like monkeys, parrots, and jaguars.
