Yes, Venus is<span> sometimes </span>called Earth's twin<span> because </span>Venus<span> and </span>Earth<span> are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. However, </span>Venus<span> and </span>Earth<span> are also very different.

I believe it’s the igneous rocks
Answer:
I haven't studied this, I think, so this is off of what I think it might be, I suppose.
Explanation:
A: If it's widespread, it might be harder to govern everyone rather than if it was more compact. If it's bigger, one center of power in one part might not be able to handle monitoring the entire country as there's al lot of space, so their influence might not be felt throughout the entire country and rather more in the areas closest to it. Like how people who lived in England were seemingly more loyal to the king, but in America, which was an ocean away, more people seemingly felt and expressed their lack of connection to a ruler so far away.
B: If it's wide-spread enough, there might be different ideas of grouping based on it. If a river runs through it, for example, it could lead to a "east of the river" versus "west of the river" difference in how they identify. An example of this is in Italy where the North and South have differences between them or how in the U.S. there had been/is the idea of "The North vs. The South" or even "The North vs. The South vs. The Midwest vs. The West Coast".

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.
