Which sentences correctly describes the effect of marine debris? Marine debris is very harmful to marine life. Its effect, however, is only limited to marine creatures, as it does not affect birds and other species
that depend on the sea. One of the major contributors to marine debris is plastic. Garbage and litter from the beach does not contribute to
marine debris. Research shows that marine debris is likely to decrease over time as plastics degrade into smaller particles. New methods of
manufacturing have been adopted to reduce material consumption and thus prevent a larger contribution to marine debris.

Hydrosphere is the correct answer

Dthrough a slow process

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
