What contributes to the movement of air masses? a. weather boundaries b. natural wind patterns c. air pressure differences d. rapid changes in weather

B). natural wind patterns, I took the Cumulative Exam.

The correct answer is option B, natural wind patterns

Explanation:

An air mass moves along with the air flow in the upper atmosphere. Whenever a jet stream changes its potion and its intensity of flow, it leads to the movement of air mass. An air mass movement is not affected by the characteristic of its source regions, however the physical characteristic of an air mass(i.e temperature, pressure of air mass etc.) are entirely determined by the physical characteristics of its source region

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

genetic variation will increase because of a new habitat and food source.
