<span>Part 2: The hierarchical level D is different from the rest because D or mars is a planet and unlike all there other astronomical bodies it dose not hold other astronomical bodies with in it. </span>
Answer:
Ferrous (Fe²⁺) and magnesium cation (Mg²⁺).
Explanation:
The olivine mineral is a type of orthosilicate, which is generally yellow to yellow-green in color. It is the main component of the upper mantle of the Earth, which can be found in igneous and metamorphic rocks.
The olivine mineral exists in the form of Mg₂SiO₄, Fe₂SiO₄, or (Mg,Fe)₂SiO₄.
<u>This silicate consists of two divalent cations, ferrous (Fe²⁺) and magnesium cation (Mg²⁺).</u>
The answer is actually Convection.
Carbon-neutral status can be achieved in two ways:
Balancing carbon dioxide emissions with carbon removal beyond natural processes, often through carbon offsetting, or the process of removing or sequestering carbon dioxide from the atmosphere to make up for emissions elsewhere.
