Answer:
Explanation:
Given data:
wavelength = 21 cm
from wein's displacement relation we have
Where,
b is wein's constant and it is given as
and T is temperature of radiation , represent wavelength
Putting all value in the above equation to obtained desired temperature value
Over time sand and silt eroded down the Gondwana land mass. This compacted and formed a sedimentary rock called graywacke.
<h3>Formation process of Tongariro Volcano Centre</h3>
The Tongariro complex of volcanic cones and craters was formed by eruptions from at least 12 vents over more than 275,000 years. Erosion during the last Ice Age has worn away what was once a substantial mountain into the world famous hiking destination that it is today.
The Pacific plate subducted under the Australian plate and volcanism began. This process resulted in magma forming 150km below the Tongariro Volcanic Centre.

Answer: The correct answer is option C, the principle of superposition.
Explanation:
In geology, the principle of superposition states that in a series of stratified sedimentary rocks, the one that sits at the bottom ( the lowest stratum) is the oldest.
According to the details given above, the geologist observed that sandstone sits on top of the granite(the granite sits at the bottom), he concluded that granite is older than the sandstones. This principle clearly demonstrates the theory of superposition.
Superposition simply means putting something on top of another (for example, placing an object on top of another object).
Therefore, the above principle describes the theory of superposition.
