What happens when friction between the opposite sides of a fault is high?
a.
a plateau may form on one side of the fault.
b.
the fault locks, and stress builds up until an earthquake occurs.
c.
folding of the crust may occur.
d.
the rocks on both sides of the fault easily slide past each other.

The answer is B. As the two sides of the fault move against each other, they might get stuck at a point. Therefore as they try to continue moving, and cannot, stress builds up between the two. When the energy builds up too high, the point at which they are stuck may immediately release or break, hence releasing a huge wave of energy from the point of release to form an earthquake. This point is usually referred to as the epicenter of the earthquake.

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.
