Now suppose a stream has a high volume but a low gradient. how might the
stream change the land? provide your reasoning.

The stream has a high volume but a low gradient will run through small rocks and small valley. It slowly runs all over the area. Even though it is low gradient its volume is high so it craves the area and then it changes the land.

Explanation:

Low gradient streams are less forced but it is wider as it slowly flows through the land. As it is separated from the high gradient stream. Then it finds its path and creates it. It will slowly eradicate the soil or land or rock which present in its path. Day by day the flow of large quantity of water will change the position of the land. Before reaching the sea, it will cover up the river.

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.

The answer is hilum.
