![](/olcweb/styles/shared/spacer.gif) | ![](/olcweb/styles/shared/spacer.gif) | B)![](/olcweb/styles/shared/spacer.gif) | The greenhouse effect is primarily due to the accumulation of carbon dioxide and other compounds in the atmosphere that cause reradiated heat from the Earth's surface to be trapped, and hence, cause an increase in the temperature at the surface of the Earth. |

20 | ![](/olcweb/styles/shared/spacer.gif) | ![](/olcweb/styles/shared/spacer.gif) Camels and horses first evolved in North America. However, they were absent when members of our species first reached what is now the United States. The terms that are most related to this phenomenon are land bridges and dispersal. |

22 | ![](/olcweb/styles/shared/spacer.gif) | ![](/olcweb/styles/shared/spacer.gif) Vicariance is often used as a synonym of allelopathy; both result in separation of one species into two by geographic barriers. |
