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.
The order is observation, question, propose a hypothesis, make a prediction, test, results, changing outlets worked, propose a new hypothesis and make a new prediction.
<h3>What is the scientific method?</h3>
The scientific method can be defined as a series of sequential steps in order to collect empirical evidence and thus test hypotheses that allow making predictions related to their outcomes.
In conclusion, the order is observation, question, propose a hypothesis, make a prediction, test, results, changing outlets worked, propose a new hypothesis and make a new prediction.

Answer:
C
because of temperature inversion
Answer:
D - People in Thailand wearing warm, heavy coats
Explanation:
The text does not mention Thailand at all.
It is impossible to build a drainage system on the outside of the Sao Francisco river as buildings are built on the outside of the foundation.
The Subarnarekha is developing a small drainage system.
The Amazon basin is the largest drainage basin in the world.
The Urugay drainage system includes the greater part of southeastern Brazil, Paraguay, southeastern Bolivia and northern Argentina
So i would suggest putting the Amazon as it is the most common known and largest. Remember to use geographical terms!
