From the use of the definition of Refractory and Volatility which means the resistance to decomposition and evaporation of matter the rocky planets or the moon as compared to the icy planets like Saturn in the solar system is quite complex.
As the host star i.e the sun is a yellow giant made of gases of hydrogen and helium has the capacity to drive away the atmosphere of the planets that nearby with the help of solar winds and the four terrestrial planets are rocky and the other end three planet are gas giants.
The planet like Saturn, Uranus and Neptune are quite far and have high densities of gases and ice, even frozen water running underground there surfaces.
As the planet becomes voitialie it loses its refractory as has happened with venus and mars. Thus even moon shows some layers of ice found in its creators.
The area between the Tropic of Cancer and the Tropic of Capricorn is often called the Tropics. (ever heard of the tropical rainforests this is where they would be found.)
Mother earth has experienced various natural climatic changes over various periods of its geologic history and due to the phase of rapid deforestation. and rapidly brought up charges by the man in the natural environment of the earth has drastically impacted the global warming of the planet.
Cutting of the natural reserves and depletion of natural resources by the man in his greed for more and more like the continuous burning of forests and fossil fuels earth has experienced major climatic drifts.
The title in the orbit of the earth is associated with the changes in temperatures and climate over various latitudes and longitudes of earth and as a result, the surface of the earth is experiencing lots of rapid changes in sea level.
As far as the asteroids are concerned no asteroid is big enough to have or has blocked the part of the earth from the solar radiation and that would have impacted the planet's insolation cycles.
