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.

GLOBAL WARMING

Five causes of global warming- deforestation, power plants, cars, over-sized population, and carbon dioxide from various things such as airplanes or buildings.

Five things you can do to prevent global warming are take a shower not a bath, cover your pots while cooking, recycle organic waste, keep your car tuned up, and consider the impact of your investments. 

Physical and Chemical Properties

physical property- any aspect of an object or substance that can be measured or perceived  with out changing its identity.    

5 examples- color, smell, freezing point, boiling point, infra-red spectrum

chemical property- a property used to characterize materials in reaction that change there identity.

Homogenous/Heterogenous

Heterogeneous mixture- any combination of substances that does not have uniform composition and properties; a mixture of physically distinct substances with different properties.

6 Examples- sandy water, carbonated beverage or beer, orange juice with pulp in it, water with ice cubes in it, chicken noodle soup.

Homogeneous mixture- any combination of substances that has uniform composition and properties; a mixture that is uniform through out.

6 Examples- salty water(salt dissolved)   brewed tea or coffee    soapy water   a dilute solution of hydrochloric acid   hard alcohol   wine

Subatomic Particles

The three main types of subatomic particles are protons, neutrons, electrons.

Protons have a positive charge, along with neutrons, which are located in the nucleus.

Electrons have a negative charge, also located in the nucleus.

Definitions

Wave length- the distance between repeating units of a propagating wave of a given frequency.

Wave frequency- measure of the number of occurrences of a repeating event per unit time.

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