Expert Solution

Step 1

Around 4.5 billion years ago earth emerged as a hot mass of gases and lava. Later by the combined action of physical, chemical and biological processes the earth cooled to form numerous features and phenomenon. By the process of condensation the waterbodies, such as oceans, seas, lakes etc. developed. Formation of the water bodies was followed by the emergence of the atmosphere and rise in oxygen level. During evolution the earth differentiated into four prominent layers, viz., the crust, the mantle and the outer and inner core.
