Differentiate between environmental science and environmentalism. Define each term and explain how they are similar and how they differ.

Explanation:  They both study and address environmental issues. The ultimate goal of both, and the similarity between them, is to improve the environment as a place of life for each of us. In both cases, meaning similarity, the role of man in improving the living environment is emphasised. The scientific approach reveals and gathers significant scientific facts and knowledge that can again be used by various environmental activists in protection of the environment in terms of both prevention and restoration of polluted natural resources.

The difference between them is that environmental science uses scientific methods to study the environment, and it can be said that they use an objective scientific approach to this problem. Environmentalists, on the other hand, use a wider range of ways to deal with this problem, often with an emotional and biased approach. Environmentalists take a wide variety of actions, which of course are not just scientific, in the pursuit of environmental improvements, living conditions. So environmental science is looking for knowledge on this subject, such as human interaction with nature and vice versa pointing it only to scientific facts within the institutions intended for such a thing. Again, on the other hand, environmentalists often have political appearances on this issue, and then they often perform dramatically in order to point out in important political places human impact on the environment, which can be detrimental to it and ultimately pernicious to the people themselves. So environmentalism can be said to be a kind of social concern for the environment and people, while environmental science about the environment with only scientific facts, and with that knowledge collected, emphasises the importance of environmental sustainability.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
