The layer is Asthenosphere. :)
What is Data Layering
A lot of GIS systems could allow for the separation of different geographic features in logical categories. These categories are called map layers. Each of these layers contains information taken from one geographic feature or from a selected small group that has related features. Because data is separated in layers, they can be easily<span> manipulated and spatially analyzed</span>
Its bigger by 100% you divide the old with the new them times it by 100 and you get your answer. please check other sources before selecting your final answer. thank
Answer: The star Alnilam is hotter
Explanation:
The question seems to be the continuation of another question, which is written below:
Use Wien's law to calculate the surface temperature of the star Alnilam in Kelvin. The peak wavelength 
of the star is 
So, by using <u>Wien's displacement law</u>, which relates the wavelength where the intensity of the radiation is maximum with the temperature 
of the black body, and expresed as:
(1)
Where:
is in Kelvin (K)
is the wavelength of the emission peak in meters (m).
is the Wien constant
We can find Alnilam's temperature and then compare it with the Sun's temperature (
):
(2)
(3)
(4)
As we can see 
, hence:
<h3>The star Alnilam is hotter</h3>
Age, size and composition,
