Answer:
The crust rides upon the mantle and is composed of both the oceanic basaltic-plate and the uppermost continental granitic-plate.
Explanation:
The mantle is one of the four layers that form the earth. It is a very hot and dense rock, that is capable of flow. The crust is the outermost layer of the earth and is located just over the mantle. The crust is divided into many plates, that are able to move over the mantle. In fact, the tectonic plates theory is based on the continual movements of the crust and might explain the movement of the different plates, and their directions and interactions. The continental drift theory explains how these movements have been taken place since millions of years ago.
The crust is composed of two layers characterized by different types of rocks. The continental layer, which is the uppermost, is mostly composed of granite. The oceanic layer, on the other hand, is mostly composed of basalt.

Explanation:
Green house effect occurs when the wavelenght of the infrared radiation in the incident solar radiation, looses some of its energy on reflection from the earth surface, making it longer and unable to pass through the greenhouse gases that act like a blanket around the earth.
The reflected radiation has a longer wavelenght because it looses energy to the earth as heat; leaving it with a new wavelenght too long to go through the greenhouse gases.
The jar envoirment does not provide the earth-like material that can absorbs some of the energy of the incident radiation so it goes out with relatively the same energy. Also, the refractive index of the green house gases and the glass used in the lab might not be the same so modeling it with a glass might not produce the same effect.
Finally, the light source used might not contain enough infrared energy as an incident solar radiation.
