Power Words

global warming A rise in the average temperature of the Earth’s atmosphere, especially a sustained increase great enough to cause changes in the global climate. Many scientists believe that the Earth has been in a period of global warming for the past century or more, due in part to the increased production of greenhouse gases related to human activity.

relative humidity The amount of water vapor in the air at a given temperature compared to the maximum amount that the air can hold at that temperature. Relative humidity is a ratio that is given as a percentage. If a mass of air has a relative humidity of 50 percent, it contains half of the water vapor that it can actually hold at its present temperature.

species One of the major groups in the classification of living things. A species is below a genus. Only organisms that belong to the same species are able to breed with each other.
