Chemicals typically have the shortest average residence time in the atmosphere. This is due to rapid processes such as precipitation, photochemical reactions, and atmospheric transport that can quickly remove or transform substances. For example, certain pollutants can be dispersed or degraded within days to weeks, contrasting with longer residence times seen in soil or sediment environments.
It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
We live on a sphere. Calculating 'shortest' distance on the sphere is not a simple trig problem, you may need spherical trig.
It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
Consider the Earth as a sphere - the fact that it is oblate is only of minor significance. The shortest route on the surface of a sphere is an arc of the Great Circle. This is a circle whose centre is at the centre of the sphere and which passes through the start and end points.
A great circle is any circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere is a part of the great circle that passes through them.
The shortest path between two points on a globe is known as a great circle route. This route represents the shortest distance over the Earth's surface, calculated by following the curve of the sphere. Great circles are formed by the intersection of the surface of the sphere and a plane that passes through the center of the sphere. Examples include the paths taken by airplanes, which often appear curved on flat maps due to the Earth's curvature.
It is the shortest distance between two points on a sphere, where the sphere in question is the earth. Particularly long airline flights follow great circle routes.
If talking in terms of the shortest distance around a sphere, the answer is NO.
actually, there is, depending on your definition of polygon, and your definition of a line segment. A line segment is the shortest path btwn two points, right? So take a sphere and pick any two points on that sphere. The shortest path between them on the surface of the sphere would be a "curve" along the surface, but it's the shortest path between the points, so it technally is a line segment. Take two of these line segments that intersect at two points, and there is your two sided polygon!
no it is not a perfect sphere because the average classroom globe shows landforms and mountains on the globe which makes it not as smooth or round
On average 16-18
