Quiz11
1.     Earth retains plenty of internal heat because it is large for a terrestrial planet, the circulation of molten metal in the core generates Earths magnetic field.
2.     Impact cratering, volcanism, tectonics, and erosion
3.     Erosion, Protection from radiation. Greenhouse effect
4.     Cratering shows that the activity ceased long ago
5.     Evangelista Torricelli was an Italian physicist and mathematician, best known for his invention of the barometer.
6.     Scientific theory that describes the large-scale motions of Earth's lithosphere.
7.     YES
8.     Convection is a mode of heat transfer, which includes the movement of the molecules of the material. It is only observed in liquids and gases. It is not possible in solids because the molecules in solids are tightly packed and are not free to move.
9.    
In thermal conduction, thermal energy (heat) transfers through a substance from a hotter region toward a cooler region. For example, when you dip a metal spoon into a cup of tea, the heat from the hot tea will conduct along the spoon so that the handle becomes warm, even though the handle is not in direct contact with the hot tea.
      In electrical conduction, free electrons pass through a substance, thus enabling an electric current.

10.The emission of energy as electromagnetic waves or as moving subatomic particles.
