Explanation:
The embryonic development of fertilized egg includes cleavage, blastulation, implantation, gastrulation and organogenesis.
Cleavage division divides the zygote into blastomeres. First cleavage division result in two blastomeres, second cleavage division results in a transient three cell stage. Third cleavage division forms 8 blastomere. These result in the formation of a sold ball of cells called morula. Morula is 16 cell stage and it descends towards the uterus in 4-6 days. As the morula enters the uterus, it gets a rich supply of nutrients. Trophoblast cells are formed which secrete a fluid into the interior creating a cavity called blastocoel. The inner cell mass now comes to lie on one side as embryonal knob. With the formation of blastocoel, morula is converted into blastula which is called blastocyst in mammals.

Answer:
Substances in nature rarely exist as single element but combination of more than one elements.
This combination of element is referred to as compounds.
These compounds can breakdown from temperature change or change in pressure and so on ,these atmospheric change exist in nature and with long climatic change over a period and could lead to elements recombining and could be transported to other areas from weathering.
