In the 16th and 17th centuries, horses escaped from Spanish explorers and developed into wild herds that did especially well in the North American Great Plains region. Why were these horses able to adapt so well to this region? • There were no predators on the plains that could take down large animals like horses or bison (buffalo.) • b. The ancestors of these horses were native to the steppes of Asia (grasslands), so these wild horses were well adapted to the North American grasslands. • c. Wild horses eat primarily leaves from small shrubs or bushes, and the North American grasslands used to have an abundance of these types of plants. • d. All of the above
The tundra and the desert biomes both receive about the same amount of annual precipitation. During the short summer, the tundra is dotted with thousands of small ponds and shallow, slow moving streams while the desert seldom holds little if any visible surface water. What is the best explanation for this? • Permafrost prevents the water from draining into the soil. • b. The low angle of the sun results in very slow evaporation. • c. The tundra is relatively flat, so most of the water does not drain away into rivers. • d. All of the above
Which geographical region experiences several weeks each year where the sun never rises above the horizon? a. The Gobi Desert b. The Arctic Tundra c. The Amazon Rainforest d. All of the above, depending upon the season.
The Camel’s Hump is a mountain in Vermont that is only a few miles from where Mr. Moore’s parents have a house. As Mr. Moore and his family start their hike up Camel’s Hump, they pass through glades of broadleaf, deciduous trees like sugar maple and red maple. Two-thirds of the way up, most of the trees are small conifers like spruce and balsam fir. Eventually they reach an altitude where there are no more trees but there are small patches of small grass, lichens, and moss. What three “biomes” did the Moore’s experience during their hike? • temperate deciduous forest- taiga like coniferous forests- tundra (alpine tundra). • b. grasslandtropical rainforest arctic tundra • c. grasslandtemperate deciduous forestarctic tundra
