Question

Geologists can inspect the concentration of carbon isotopes in the rock record to learn about ____________.

rates of burial of organic material

global climate change

rock weathering rates

All of the above

Carbon is cycled through the atmosphere mainly as carbon dioxide, through the biosphere as organic carbon, and through the lithosphere as _________________.

calcium carbonate

basalt

glaciers

granite

rates of burial of organic material

global climate change

rock weathering rates

All of the above

Explanation / Answer

in many ways a geologist can estimate the property of any earth element. if a geologist get a sample of rock then by estimate the composition of that rock he can learn about various types of properties of that geographical area. they can determined the age of rock by carbon isotops detection and by this they can get many data related to geography.

so a geologist can inspect the concerntration to carbon isotops can learn about the rate of burial of the organic material, global climate change ,rock weathering rate

so correct answer is all of the above

-----------------------------------------------------------------

according to the carbon cycle it is stated that in atmosphere it is found in the form of carbon dioxide, through the biosphere it is found as in the form of organic carbon compounds as in this sphere all the living beings are survive. and through the lithosphere it is found in the form of some specific rocks, coal and the fossil fuel.

but basalt is having carbon in its composition and it have black carbon texture in it.

so correct answer is basalt
