Layers of shells from once-living organisms and sediment are cemented together and turn to rock, storing the carbon in stone cal

kodGreya [7K]

Answer:

Sedimentation.

Explanation:

The process that is responsible for the movement of carbon atoms from the biosphere to the geosphere is called sedimentation. Carbon enters the geosphere or lithosphere through the biosphere when dead organic matter becomes incorporated into the soil that turns the shells of calcium carbonate to become limestone through the process which is called sedimentation. This sedimentation process is very necessary for the formation of different types of minerals such as limestone, fossil fuels etc.

In an ionic compound, the attraction between actions and _________ hold the compound together

Nady [450]

Answer:
The correct option in blank is anion.

Explanation:
Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.
