Answer:
Radiometric dating is usually defined as a method that helps in calculating the age of rock depending on the presence of radioactive isotopes and its rate of decay. In order to calculate this, the half-life of the isotope element must be known. This method is commonly used by geologists.
The conditions that are needed to fulfill in order to determine the age of a granitic batholith are as follows-
- The rate at which these materials decay must be a constant
- There should be an exact amount of both the parent as well as the daughter elements.
- Since it is a batholith, so it has formed from the crystallization of magma at a certain depth. So, these granitic rocks must have remained within a closed system, right from the time of its formation.
The various methods of radiometric dating that can be used to date this granitic batholith are-
- Uranium-lead dating- It is an efficient method to date the rocks that are of about 4 to 4.5 billion years.
- Potassium-argon dating- It is also commonly used to date rocks that are about 4 billion years old.

Explanation:
In Euromoneymagazine's 2017 semi-annual "Country Risk Rating. Singapore and Hong Kong was found to be the countries with the lowest political risk. This was as a result of stability in government which reduces the risk that their government would default on its financial commitments. And no possible changes in the business environment that may negatively affect operating profits.
Answer:
1) USING GAS IN THE HOME
2) USE IN THE INDUSTRIAL SECTOR
3) TRANSPORTATION
Explanation:
Aside from electricity, the residential sector of society uses natural gas to heat up buildings, water, cook meals, and dry clothing. Pretty much anything that needs to be done in the home or commercial building that involves heat, is able to get done thanks to the production of natural gas.
Antifreeze
, Plastics, Pharmaceuticals, Fabrics, Ammonia, Methanol
, Ethane, Propane
According to studies, vehicles that utilized natural gasses emitted 60-90 percent less smog-producing pollutants and 30-40 percent less in greenhouse gas emissions. Also, with its production and distribution within the United States, the cost for its use in transportation vehicles is substantially less than the gas that is imported from other nations.
