Hmm... let me see. Hey, Mom, what's the answer? Oh, that's right. The Exosphere is the answer to this question.
The exosphere is the highest level and it has the least air.
The layer of the atmosphere is the least dense is thermosphere
the lowest layer of air which is called the first atmosphere.
On the Earth, the Earth's crust has the least average density.
the upper most atmospheric layer has the lowest air density.
ex
(most dense to least dense) gold, mercury, water, oxygen
the lonosphere
The mesosphere is where meteorites burn up. Most people call them shooting stars.
the layer that has convection currents is the mantle
Troposphere
The atmosphere.
Thermospehere
No. The atmosphere is the least dense layer. The densest layer is the inner core.
Basically, the higher you get in the atmosphere, the less dense it gets. It's the exosphere.
the exosphere, which is the highest layer of Earth's various layers of the atmosphere. it is the least dense because it is so high up the molecules are spread apart a lot.Type your answer here...
Thermospehere
The exosphere is the least dense part of the earth's atmosphere.
It is neither. The densest layer is the inner core. The least dense layer is the crust.
The Exosphere.
The Mesosphere is the least studied layer of our atmosphere.
The core is the most dense layer
The Troposphere is the thickest layer of the atmosphere.
