Compare how humans have impacted the tundra and the rainforest.
Humans have had an impact on both the tundra and the rainforest. Oil drilling and mining are a problem in both biomes. Overgrazing, erosion, and radioactive pollution are the result of human impact on the tundra biome, while logging agriculture, and construction are of greater concern in the rainforests.
What developments occurred from the Jurassic period to the Cretaceous period?
Dinosaurs were common in the Jurassic period, but during the Cretaceous period they went extinct. Pangaea had fully split by the Cretaceous period and angiosperms had developed.
Explain why biomes are not typically classified by temperature.
Biomes are typically not classified by temperature, because some biomes can experience extreme temperatures from one season to the next. Other biomes might have a more consistent temperature throughout the year. Climate is a better tool for classification.
Compare the Carboniferous period to the Devonian period.
