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>
Through the perspective of geomorphology, geography is a science that has it focus on the origins and evelution of the topographic features and bathymetric features, that have been created under the influence of physical, chemical, or biologic processes that are operating on the Earth's surface, or near the Earth's surface.

An aquifer is basically a body of saturated rock meaning water doesn’t have a hard time passing through it must be permeable and porous which includes sandstones, conglomerate, fractured limestone, and unconsolidated sand and gravel.if the rocks are fracture it makes a good aquifer
