Is global warming caused by "man"?

Yes, for the most part global warming is caused by man. Scientists have evidence such as pollution and man-made green house gases have started tearing away the atmosphere. Natural green house gases have less water vapor and harmful effects on the environment.

One natural cause of global warming is the emission of methane from the artic tundra and wetlands.

Physical Properties- Any aspects of an object or substance that can be measured without changing it's identity.
5 Examples: Density, Color, Boiling Point, Mass, and Strength.

Chemical Properties- Any quality that can be established only by changing a substance's chemical identity.
5 Example: Flammability, Toxicity, pH balance, Heat of combustion and Electronegativity.

Heterogeneous: non-uniform distribution of components.
Example: kool-aid, air, water, soda pop,juice,carbon

Homogeneous: Composed of one phase only
Example: Chocolate chip cookie, gravel, dirt, soil, plants, rocks, seeds

Defenitions Wave Legnths

Wavelength-the distance, measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.

Wave frequency-frequency refers to how many waves are made per time interval (this is usually described as how many waves are made per second or as cycles per second).

Wave height-the vertical distance between the crest and the preceding through of a wave.
