Explanation:
One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O2) in the atmosphere. Chemical bonds are created and destroyed to finally make iron oxide (Fe2O3).
<h2>Answer : Daniel was related to study of Earth and Space
</h2><h2>Whereas Sanya was closely related to chemistry</h2><h3>Explanation :</h3>
As in the given information, Daniel the scientist was studying the effect of tropical storms on coastal erosions. These studies comes under the field of Earth and Space. Earth because coastal erosions are involved in the study, and Space because storms are discussed which is something related to space.
In case of Sanya, it is clear that her study focuses on discharges from the industrial plant that has effect on freshwater swamps. Precisely, she is studying the pH concentration which comes in chemistry.
This prove that Daniel studies Earth and Space whereas Sanya studies Chemistry.
