Statements that are true as regards Earth’s spheres are;

A - earth’s spheres depend on each other

B - to maintain equilibrium, energy and mass is transferred between spheres

C - earth’s spheres support each other

There are four spheres that can be attributed to the Earth, and all these sphere are depend on each other. They are lithosphere, hydrosphere, atmosphere as well as biosphere. The lithosphere is the part that has solid rock, soil in it, to maintain equilibrium, there is usually transfer of mass and energy among the sphere.

Therefore, all options are correct.

Answer from: tyrique86

Option A, B and C.

Explanation:

The Earth spheres make up the components of the Earth and it comprises of both living and non living things.

The Earth spheres(hydrosphere, biosphere, atmosphere) are interconnected with each other. A change in a sphere can also in one way of the other influence change on the others. Interactions occur among the spheres I .e energy can be harness from one sphere to another.

For example birds can fly from biosphere to hydrosphere to obtain water. Their interactions cause or drive all the processes of the Earth which is an indication that they are connected to each other and react with each other.

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.
