The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.

Environmental Sciences is a multidisciplinary academic field that integrates biological, physical and information sciences for the study of the environment and solutions to environmental problems. These sciences include physics, ecology, zoology, biology, chemistry, mineralogy, oceanography, geology, soil sciences, atmosphere sciences and geography. The environmental sciences emerged from the fields of natural history and medicine. Today, they allow an integrated, quantitative and interdisciplinary approach to the study of environmental systems.
Related areas of study include environmental studies and environmental engineering. Environmental studies integrate social sciences to understand human relations, perceptions and policies regarding the environment. Environmental engineering focuses on design and technology designed to improve the quality of the environment. Environmental problems almost always include the interaction of physical, chemical and biological processes. Environmental scientists work on topics such as understanding ground processes, assessing alternative energy systems, controlling and mitigating pollution, managing natural resources and the effects of global warming, applying systemic analyzes to environmental problems.
Environmental sciences became an active field of scientific research in the 1960s and 1970s, due to the need for a multidisciplinary approach to analyzing complex environmental problems, the emergence of various environmental laws requiring specific research protocols, and increasing public awareness. the need for action to solve environmental problems.
