Climate change is caused mainly by changes in the balance between the amount of solar radiation received by earth and the amount of heat radiated back into space by the earth.

Yes, that is very much true, just because climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount of heat radiated back into space by the Earth.

Climate change:

"The change in stability of the environmental factors or the negative effects  in the equilibrium inside the environment is called as the climate change."

Global Warming And the green house effect:

"The overall rise in temperature of the earth spheres and its environment is termed as global warming, and its due the green house effect(the negative effect due to the increase level of CFC's)."

The trapped Sun radiation inside the earth's sphere:

"Due to large number of CFC's inside the earths sphere, as they results in trapping the radiation which needs to be radiated back out of the earth's sphere. Causing the rise in temperature of the overall environment."

Explanation:

The chloro, floro and carbon elements which are also termed as the CFC's in general are created due increase level of industrial waste presence in the environment, leading to more solar radiation trapped inside the outer sphere of the earth's protective shield. Due, to this process the gasses are trapped inside the earth's sphere resulting in the rise in temperature.Consequences of Climate Change:As our earth passed from various levels and situations and as there were also some ice ages, which almost resulted in creating inhabitable situations for the living beings.But, these days earth is facing some alarming situations in the form of high temperature in its environment, which is some how leading to some thing more worse.There will be less resources of food in the near future and most importantly there will be species like polar bears and some marine animals who will face extinction due to the rise in temperature inside the environment.

Answer// dinosaurs emerged during mesozoic era;

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.
