Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Natural selection is a theory developed by Charles Darwin. It is believed that animal species evolve by nature "selecting" the ones that are fit to live in specific environments. For example, if an animal lacks a trait that is needed for a certain environment, it is likely to die. The animals that have the needed traits are more likely to live and procreate, which will pass on the trait to its offspring. Hope this helped!
Freezing rain refers to the rain that falls through a shallow layer of cold temperature at zero degree Celsius or below zero degree Celsius near the earth surface. Celsius and Fahrenheit are two types of measurement that are used to measure temperature. The freezing temperature of water is zero degree Celsius. Zero degree Celsius is the same thing as 32 degree Fahrenheit.
Thus, the thermometer reading that is expected from a thermometer near the earth's surface during a period of freezing rain is 32 degree Fahrenheit.
Predictions about the future based on the position of planets is an example of astrology.
