Answer:
The differences can be seen in the top layers, where one is hard and the other one barely has anything in it, and in the distribution of temperature across the layers.
Step-by-step explanation:
The layers of Earth and the layers of Earth's atmosphere have several similarities, but they also have several differences. The most obvious difference between the two types of layers is that Earth's layers are mostly made out of metals, while the atmosphere is mostly made out of gases.
Other differences are the distribution of temperature across the layers and the structure of their top layers relative to the other ones. In the first one, the difference can be seen in that the Earth's layers have the highest temperature in the bottom part, and the temperature drops as we go toward the top layer, while in the atmosphere there is a liner increase or decrease from top to bottom, but oscillations throughout it. In the latter one, Earth's top layer is the hardest one, being very dense and composed of rock, while the atmosphere's top layer has only sparsely distributed molecules and is very similar to a vacuum.
