Mountaineers caught in storms sometimes survive by digging a cave in snow. How do they keep warm in an ice cave? Why do telephone wires hang higher in winter than in summer? Why does air rise at the equator? How does Earth retain its atmosphere?
How do prevailing winds affect the movement of air masses? Why does warm air rise? Why is the troposphere thicker at the equator? How do air currents affect climate? Why are temperatures lower at higher altitudes? How does air pressure affect evaporation?
Why does warm air rise? Why does a hot air balloon rise when it is heated? Why does air pressure decrease as altitude increases? Why does the temperature increase in the stratosphere? Why does air have pressure? What causes atmospheric air to be rapidly heated? Why does temperature increase...
When air in a particular area is heated, you get a concentration of warm air in an area of low pressure. 当特定区域的空气被加热时,热空气会聚集在低压区。 Likewise, when you get a concentration of cold air, that air's gonna be very dense, so it's gonna create an area of high pressu...
As the warm air rises it expands and cools. Since cool air cannot hold as much moisture this often results in rainfall. The cooled air is then drawn back towards the poles, sinking towards the earth to replace the air moving along the surface towards the equator. This cycle of air movemen...
The Earth orbits the sun on its own axis, which is tilted at 23.5 degrees, meaning that the hemispheres lose warmth from the sun when they tilt away. The axial tilt and the Earth’s orbit also means that at certain times of the year, the sun sits right above the equator. This ...
Does temperature affect air pressure? Cold airis more dense, therefore it has a higher pressure. Warm air is less dense and has a lower pressure associated with it. ... Remember, heat is less dense than cold air so the warm air will rise. This rising motion creates a natural vacuum lowe...
"When you’re actually looking out the window and seeing mile after mile of warm ocean water where there used to be sea ice that you once walked around on, it gives you the certainty that something major is going on there," says James Overland, a marine environmental researcher with the ...
On a much larger scale, a similar thing is witnessed in the tropics, where hot air is continually being pushed upwards, where it spreads to the north and south, while high-pressure air from the north and south are summarily pulled into these tropical areas, where it will start to warm up...
Now as air is heated, and becomes warmer, it expands, it becomes less dense.When air in a particular area is heated, you get a concentration of warm air, an area of low pressure.Uh, likewise, when you get a concentration of cold air, that air's gonna be very dense, so it's gonn...
