Sophia had been reading about the history of the Earth. She was surprised at the different ways geologists learn about the ages of rocks. Why is it important for geologists to use both relative and absolute ages to determine the age of rocks? A. Scientists want to learn about the age of rocks.
B. Scientists need only one way to determine the age of rocks.
C. Scientists may not be able to determine the absolute age of some rocks.
D. Scientists can tell the age of rocks using the law of superposition.

b i think it’s a water wheel turning in a stream

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

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.
