Which currents are deflected by the eastern coastline of the continents? a) north pacific current equatorial currents b) western boundary currents c) gulf stream

The correct answer is option B, that is, western boundary currents.

Explanation:

The Western boundary currents get deflected by the eastern coastline of the continents. The western boundary currents refer to the deep, warm, narrow, and fast flowing currents, which produce on the west end of the ocean basins because of the western intensification. They conduct warm water from the tropics poleward. Some of the examples of western boundary currents are the Agulhas current, Gulf Stream, and the Kuroshio.

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.
