The prepositional phrase is "...across the sky." "Across" is the preposition, and "the sky" is the object of the preposition.
The comet is moving quickly across the sky.
The Joplin tornado was generate by a supercell thunderstorm associated with a storm system moving slowly across the Midwest. A downdraft within the usually strong supercell caused the storm's rotation to tighten and intensify into a violent tornado.
No, tornado alley is not moving east. It will always be a region of high tornado frequency. You may be referring to the relatively high frequency of tornadoes in the Deep South, which is called Dixie Alley. There are plenty of tornadoes here as well, just not quite as many as Tornado Alley in the Midwest.
It depends on the size of the tornado and how fast it's moving. Most tornadoes will only be over a given spot for a few seconds. A large tornado moving at normal speed may be over a spot for a minute or two. However, one tornado was noted to have stayed on the same spot for 90 minutes.
Radar does not scan for cloud patterns. In the case of finding a tornado it looks at wind speed. If a winds are moving very fast towards the radar and winds moving fast awaay from it in a small area, it means strong rotation and a possible tornado.

Moving deftly across the ice, the skater performed her routine perfectly.
It depends on the size of the tornado and how fast it's moving. Most tornadoes are not over any sport for more than a few seconds, but a large tornado may be over an area for a minute or more. In one instance a tornado remained on the same spot for 90 minutes.
How fast a tornado is moving refers to how fast the tornado itself travels from point A to point B. For example, a tornado moving towards at 30 mph and is a mile away will reach you in 2 minutes. The rotational winds of a tornado refers to how fast the tornado itself is spinning, which is generally faster than its forward speed.
When warm air moving above mixes in with cool air moving below.

On March 18, 1925 the Tri-State tornado tracked across parts of Missouri, Illinois, and Indiana. With a death toll of 695 it was the deadliest tornado in U.S. history. The tornado traveled 219 miles in 3 hours and 29 minutes, at times traveling at 73 mph. This makes it the farthest traveled, longest lived, and fastest moving tornado ever recorded. It was an F5 on the Fujita scale and at times was up to a mile wide.

The energy in a tornado is kinetic energy, primarily in the form of very fast moving winds.
Air is continuously moving up in a tornado. This means that air surrounding the tornado must move in to replace the rising air.
