Can you determine where each sample was from? use what you know about relative salinity and its global variation. label the samples accordingly and complete the two sentences with labels that correctly describe seasonal sea ice melt and seawater freezing and the relationship to salinity. samples were collected at the locations of the circles on the map.

Answer no 1

Location that experience seasonal sea water freezing have increased salinity in the surrounding seawater during that time.

When water freezes, it form sea ice which expel out salt into surrounding water and increase the salinity of surrounding seawater.

Answer no 2

Location that experience seasonal ice melting have decreased salinity in the surrounding sea water during that time.

Answer no 3

Sample A which has high salinity content and taken from Atlantic ocean represent just east of the Bahamas

Answer no 4

Sample B which has moderate to low salinity is represent off the West coast of Africa near the equator.

Answer no 5

Sample C which has high salinity content is taken from Red Sea.

Answer no 6

Sample D which moderate to low salinity content, is taken from Baltic Sea.

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."
