What else can I help you with?
Where is the air the least dense?
The farther away from the Earth's surface, the less dense the air will be. Of course, once you break out of the atmosphere, there will be no air around you.
What part of the atmosphere is least dense?
The exosphere is the least dense part of the earth's atmosphere.
Why is atmosphere more dense at sea level than a mountain top?
the atmosphere isn't more dense. if the atmosphere was on the ground, we would have no air. but the reason the air is thinner in the mountains like mt. Everest and Kilimanjaro is because its further away from the earth center and the gravity has less effect on the air. the closer to the earth center the stronger gravity, the denser air.
Why does the atmosphere be comes less dense as altitude increases?
The air at any given layer in the atmosphere is compressed by the weight of the air above it. As you go up, there is less air wieghing down from above, so the surrounding air is less compressed.
Why is 75 percent of the atmosphere's mass found in the troposphere?
The majority of the atmosphere's mass is concentrated in the troposphere because this is the layer closest to Earth's surface where air is most dense and pressure is highest. As you move higher up in the atmosphere, the air becomes less dense and pressure decreases, leading to a decrease in mass as well.
Is earths atmosphere much thinner and less dense than mercury's?
No
What happens when you rise higher in the atmosphere?
The air becomes less dense.
What atomospheric layer is least dense?
Basically, the higher you get in the atmosphere, the less dense it gets. It's the exosphere.
Why do convection currents take place in the atmosphere?
cold air is less dense
How does air change the higher up in the atmosphere you go?
It becomes less dense.
Is there any atmosphere around mars?
Yes. Its atmosphere is much less dense than the Earth's, but still present.
Why does the density of the atmosphere decrease with height?
The Earth's atmosphere declines with altitude.
Which is part of the convections cycle in Earth's atmosphere?
hot, less dense air rises
What is the order of earths layers from less dense to most dense?
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Does humid air rise or sink in the atmosphere?
Humid air rises in the atmosphere because it is less dense than dry air.
How does hot air rise in the atmosphere?
Hot air rises in the atmosphere because it is less dense than cold air. When air is heated, its molecules move faster and spread out, making the air less dense. This lighter, less dense hot air then rises above the denser, cooler air around it. This movement of hot air rising and cold air sinking creates convection currents in the atmosphere.
