Hakase! I am planning to take the second exam in Earth Science. Are there any frequent points that I should know about?
Hakase
Of course there are. In this article, I will carefully select and explain the 3 most frequently asked points that have been asked many times in my analysis of the national secondary examination Earth Science.
Many of you may be confused by the lack of information about the second examination Earth Science.
And moreover, you feel like you have to solve and find the frequent points of the second examination Earth Science by yourself. (I was the same way…).
In this article, let’s learn with the guinea pigs about those frequent points that have been asked over and over again!

Frequent point 1: Compositional differences between basalt and rhyolite
Answers Here!
Hakase
The first point that comes up frequently is the difference in composition between basalt and rhyolite.
Plagioclase in basalt is rich in Ca, while plagioclase in rhyolite is rich in Na!
Plagioclase in basalt is rich in Ca, while plagioclase in rhyolite is rich in Na!
Chi-ga kun
Even though they have the same name, plagioclase, they have different compositions!
Hakase
Yes, it is. In my experience, this problem is the most frequently encountered.
Chi-ga kun
I’ll remember that one!
Frequent point 2: Evidence that global freezing occurred during the Proterozoic Era
Answers Here!
Hakase
The second point that comes up frequently is “why global freezing occurred during the Proterozoic Era.”
The answer is that glacial deposits have been found near the equator during the Proterozoic Era.
The answer is that glacial deposits have been found near the equator during the Proterozoic Era.
Chi-ga kun
If glacial deposits are found at the equator, where it is hot all year round, that could be evidence that the entire globe was frozen!
Hakase
Yes, that’s right. Let’s keep dropstone as a typical glacial deposit!
Frequent point 3: Why the Earth has a layered structure

The third point that comes up frequently is “why the Earth has a layered structure.
The answer to this question is that heavy elements such as iron and nickel sank into the Earth’s interior during the magma ocean, shortly after the Earth’s birth.
The answer to this question is that heavy elements such as iron and nickel sank into the Earth’s interior during the magma ocean, shortly after the Earth’s birth.
Chi-ga kun
Since the earth was covered by an ocean of magma, this layered structure was created!

In this article, I have explained the three most frequent points of the second examination Earth Science, for which there is not much information available.
You’ll need to practice past papers to reach a passing score, but let’s start with these three!

I’m going to review what I’ve learned this time and prepare for the second exam, Earth Science!
Hakase! Thank you for teaching me today!
