1. According to your regression analysis, mammal diversity is best predicted by which of the following?

a. Precipitation

b. Potential evapotranspiration (PET)

c. Actual evapotranspiration (AET)

d. Tree species richness

2. According to your regression analysis, tree diversity is best predicted by which of the following?

a. Temperature

b. Precipitation

c. Potential evapotranspiration (PET)

d. Actual evapotranspiration (AET)

3. The theory of plate tectonic explains how Earth's continents move. According to this theory, which of the following statements is FALSE?

a. Earth's crust is composed of relatively thin, light plates that float atop the dense, viscous upper layer of the mantle.

b. Ocean basins grow as one wedge-shaped oceanic plate plows through another, causing the ocean floor to split and spread apart.

c. Continental plates have relatively stable shapes because they are lighter than oceaic plates and tend to slide up on top of oceanic plates where the two collide.

d. Many of Earth's mountains results from the collision of two continental plates along a convergent boundary.

4. Although primates are widely distributed, biogeographers have debated the origin of South American monkeys. Some argue that monkeys originated in Africa and dispersed to South America. Others argue that the separation of South America from Africa is responsible for different species on the two continuents (vicariance). Which of the following, if true, would allow you to reject one of the two hypotheses?

a. If fossil evidence places New World monkeys in South America well before South America separated from Africa, you must reject the dispersal hypothesis.

b. If South America separated from Africa about the same time that South American monkeys diverged from African monkeys, you must reject the dispersal hypothesis.

c. If the separation of the two continents occurred well before the arrival of the common ancestor of African and South American monkeys, you must reject the vicariance hypothesis.

My answers.... B and B

5. What would happen if Earth's axis of rotation were not tilted but instead were perfectly perpendicular to the plane of its orbit around the Sun?

a. Seasons would be more pronounced

b. Seasons would be less pronounced

c. There would be no difference in average temperature between the poles and the Equator

6. Which biome has a plant community dominated by grasses and a climate characterized by an intermediate amount of rainfall, warm summers and cold winters.

a. Arctic tundra

b. Temperate grassland

c. Tropical savanna grassland

d. Desert

Explanation / Answer

1. (b)

According to your regression analysis, mammal diversity is best predicted by Potential evapotranspiration (PET)

2. (d)

According to your regression analysis, tree diversity is best predicted by Actual evapotranspiration (AET)

3. (b)

Ocean basins grow as one wedge-shaped oceanic plate plows through another, causing the ocean floor to split and spread apart is not a part of plate tectonic theory .

4. (c)

If the separation of the two continents occurred well before the arrival of the common ancestor of African and South American monkeys, you must reject the vicariance hypothesis.

5.(b)

if Earth's axis of rotation were not tilted but instead were perfectly perpendicular to the plane of its orbit around the Sun then seasons would be less pronounced.

6.(b)

Temperate grassland has a plant community dominated by grasses and a climate characterized by an intermediate amount of rainfall, warm summers and cold winters
