Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.
Explanation:
The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.
This is almost equal to the surface temperature of the sun which is around 5,500° C.
Where is the map for this question?
Because many mountain dominate the landscape along the coastlines, the most likely tectonic boundary to have created these ranges is the convergent boundary.
<h3>What is the convergent boundary?</h3>
A convergent boundary refers to a plate boundary where two or more lithospheric plates collide together.
In conclusion, as the plates collide, its made a plate eventually slides beneath the other which creates subduction.

Answer:
C) X=100%; Y=0%
B) X=50%; Y=50%
Explanation:
The oldest rocks on Earth are about four billion years old. When a rock forms, it contains unstable isotope and no daughter isotopes, so every rock will contain 100% parent isotope and 0% daughter isotope.
The half-life of the radioactive isotope Of this particular rock is 5730 years. The half-life is an amount of time needed for half of the parent isotope (50%) to become a daughter isotope. In this case, after 5730 years, half of the initial parent isotope will transform to daughter isotope, which means that after 5730 years, there will be 50-50 of the parent and daughter istotopes presented in the rock. After two half-lives, there will be only 25% of the parent isotope remaining (that’s half of the previous 50% which remained after first half-life), and after three half-lives, there will be only 12,5% of the parent isotope remaining and so on.
