Why is cause effect sequence central in a high level explanation of Earth's evolution?

Answer and explanation

Correct answer: Because each stage created conditions necessary for the next stage

Earth’s evolution was a sequence of interconnected causes and effects. For example, planetary accretion was followed by internal heating and differentiation, which formed layers; later, outgassing contributed to the atmosphere. Thus, each stage created conditions needed for the next one. Option B is incorrect because these processes occurred over different periods, not simultaneously. Exam tip: present events as ‘cause → effect → next stage’ rather than as an isolated list.
