Which element in magma is most abundant

In magma, oxygen is the most abundant element.

The answer is Oxygen

Explanation:

Magma is composed of a mixture of molten materials with varying amounts of dissolved gases and small amounts of solid materials such as crystals and rock fragments. Magma originates in the deep areas of the interior of the earth between the upper mantle and the crust, so it can be known that the main components of magmas are the most common elements of that area, where eight elements form between 98 and 99% of the total mass of the earth's crust and almost half of it is oxygen. Oxygen comprises 46.6% of the composition of magma.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
