Percy finds a rock in his backyard. It looks like several pebbles cemented together. Percy has found a conglomerate rock.

A conglomerate rock is a clastic sedimentary rock that is composed of large rounded clasts such as pebbles, boulders, granules, and cobbles. Conglomerates are formed when gravel are subjected to wave action and are moved far enough from their original source to become rounded. Conglomerates usually have finer grained sediment (matrix), such as sand, or silt, and are usually cemented together by silica, calcite or iron oxide.

Answer

Clastic Sedimentary Rock

Explanation

Percy finds a rock in his backyard. It looks like several pebbles cemented together. Percy has found a clastic sedimentary rock. Clastic sedimentary rocks are made from automatic weathering trash. For example breccia, conglomerate, sandstone, siltstone, and shale. When diffused bodies hasten from the liquid, synthetic chemical rocks are formed. Another example, rock salt, iron ore, chert, flint, some dolomites, and some limestones. It is formed by pre-existing particles of rock.

Genetic engineering is the answer.

Answer from: Quest

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.
