Answer:

True

Explanation:

  • Earlier earth atmosphere was devoid of any oxygen gas, it was later when the evolution of cyanobacteria took place that gave off atmospheric oxygen as the earlier atmosphere was captured by solar nebula mostly of helium and hydrogen gases.
  • Later on, the earth released volatile gases as the development of volcanicity. Hense a greenhouse rich atmosphere but poor in oxygen, as the earlier formation of air was these carbon-based gases and along with ammonia and free hydrogen. The atmosphere was nitrogen carbon and smaller amounts f gas.  
  • Some models predict that the earth would have been made up of ice. carbon dioxide produced due to volcanic eruptions and methane due to organisms but got quickly destroyed by solar radiation some 4.4 Ga years ago.

Sally has touched a hot pan on the stove and burnt her hand. This example shows what type of heat transfer?
Minchanka [31]

Answer:

Transfer of Heat

You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. Why does it cool down? The heat is transferred from the pan to the surroundings. So you can understand that in both cases, the heat flows from a hotter object to a colder object. In fact, in all cases heat flows from a hotter object to a colder object.
