Explanation:
Cenozoic = 100 mil years (rounded) = 66 real
Mesozoic = 200 mil years (rounded) = 174 real
Paleozoic = 300 mil years (rounded) = 330 real
Cenozoic = 100mil/4.6bil = .0217 (x100 for percentage) = 2%
Mesozoic = 200mil/4.6bil = .0435 (x100 for percentage) = 4%
Paleozoic = 300mil/4.6bil = .0652 (x100 for percentage) = 7%
Answer:
an auspicious or easy way or means to achieve something: the royal road to success. a highway in ancient Persia, 1,677 miles (2,700 km) long, extending from Susa in W Iran to W Asia Minor.
Explanation:
Co-Creation Theory
One idea says the Earth and Moon formed
side-by side out of the same dust and gas. Over time, their close
proximity might have caused the Moon to fall into orbit around Earth.
Why: Makes logical sense... and i have always known this one theory...

Wind power are very noisy actually horizontal axis wind turbines are mounted near the ground surface causing more noise than vertical axis.
No pollution since it's renewable source.
We don't use it in cities but in vast empty areas.
Yeah , it's not available all the time as it depends on wind and no human has power over that.
Answer:
(B) As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
Explanation:
From the theory of the formation of the solar system, the solar nebula which is a massive interstellar cloud flattened into a disk shape as it collapsed due to the gravitational potential energy which was converted to kinetic energy and ultimately thermal energy. This then allowed nuclear fusion to occur and a protosun was formed at the core of the nebula.
Initially, the particles that constitutes the solar nebula were moving randomly in an uncordinated fashion. As the gravitational pull reoriented the particles into a more coordinated pattern. The pull contracted the vast nebula into a smaller size and this was furnished with a kinetic energy. This energy resulted into the heating of the nebula and the centre became very hot. The gravitational pull caused an inward pull on the particles while the pressure of the condensed nebula resulted in an outward pull.
