1. What are some of the steps to the scientific method?

These are some steps  - it usually is listed with 5 basic steps.  Feedback could be the additional step.

Explanation:

Make an observation.  After you make an observation ask a question.  Now you will be able to form your hypothesis - what is it that you are going to test?  Now, you can make a predication based on the hypothesis that you created.  Make sure to test the predictions that you make.  Collect data.  Check to see if others have done any work like you are collecting data on.  Use data to make your final decisions - based upon the hypothesis and predictions that you made.  If you get confused or lost - start again and change your hypothesis.  Always, always, always reflect on your results.  Make sure to use DATA to back up what you find.  

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
