Which of the following provides evidence that supports the continental drift theory?10 points a.) fossils of the same organisms found in different continents b.) magnetized rocks that do not match with the poles c.) seafloor spreading d.) volcanic activity

   A) Fossils of the same organisms found in different continents

Explanation:  Continental drift is a theory, according to which, for a long period of time, continents moved one against the other across the ocean bed. This theory has been developed by several scientists, supplemented, rewritten, etc, but in essence this theory is explained by the theory of the tectonic plate, that is, the continents move by floating on the plates of the Earth's lithosphere. Evidence for this are similar fossils, animal and plant, found on different continents, which means that they were formed once on the same, one continent, before the separation and floating of continents one in relation to the other.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
