The sandstone is older.in order for the granite to have been formed with sandstone in its precnese then it had to have already exsisted in that area..making it older.
Answer:
A
Explanation:
The specific heat capacity can be defined as the amount of energy that is required to raise the temperature of 1kg of a body by exactly 1k.
When calculating the amount of heat required, we usually employ the use of the formula that relates the amount of heat, the mass of the body, the specific heat capacity and the temperature change. The amount of heat is represented by H, the mass of the body by m, the heat capacity by C while the temperature difference is represented by delta T
When this reaction occurs, strong ionic bonds form between two oppositely charged particles (ions). Magnesium is a group II metal, and therefore has two electrons in it's highest energy level (or outermost electron shell). ... Therefore, they readily take up these two electrons to form negatively charged O2- ions
Usually the controlled experiment is the one that is not tested so they look at the experimental experiment to find the differences. Sorry if this doesn't answer your question.
