Answer:
False
Explanation:
The given statement is false,the Aging of sedimentary rocks can be easily done with direct dating of the Volcanic Ash layers. Moreover, sedimentary are layered the older layers are at the bottom and the younger layer are at the top. Although sedimentary rocks do not contain radio active element but their absolute age can be determine by direct dating of the Volcanic Ash layers.

Answer:
Option D.
Explanation:
Mars is far from the Sun (less warmth from the Sun) and very little greenhouse warming due to its very thin atmosphere, is the right answer.
As the earth is distant from the sun so as the heat of the sun does not reach to mars. Another important reason why the climate on Mars is cold is that barren planet also has a shallow atmosphere that is 95% carbon dioxide. The distribution of Mars’ climate is remarkably comparable to Venus’, one of the least congenial atmospheres in all of the Solar System.
Answer:
A particle or packet of light.
Explanation:
A photon essentially doesn't have a charge and thus can't be called an electron. So, option 1 is incorrect.
Photons are in fact packets of electromagnetic energy that light is made up of. So, option 2 is correct.
A photon is not a gaseous mass that indicates the preliminary stage in a star's growth and thus can't be a protostar. So, option 3 is incorrect.
Photons having different energies are constituents of the electromagnetic spectrum and thus a single photon can't be a spectrum. So, option 4 is incorrect.
