Answer: c. Later Copernican Revolution (about 1609-1630)
Explanation:
During the Middle Ages, it was believed that the Earth remained motionless, occupying the center of a universe subject to uniform circular motion where Earth was the only world. All this because the only accepted idea was that of Ptolemy.
Until the Polish astronomer Nicolaus Copernicus proposed that the Earth annually orbits the Sun and rotates once a day on its own axis. He also dared to affirm that the other planets also orbited the Sun as a fixed point. This meant the Earth was no longer unique, nor did it occupy the center of the known universe.
It was on this main idea that the Copernican revolution was based, by changing the Earth for the Sun as the center of the Universe, bringing with it a paradigm shift from the ptolemaic model of the heavens (the stationary Earth in the center of the universe) to the heliocentric model with the Sun in the center of the solar system.
These ideas were published by Copernicus in <em>De revolutionibus orbium coelestium.</em>
The speed of a river varies from close to 0 m/s to 3.1 m/s (7 mph). Factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides. Rivers tend to flow from a higher elevation to a lower elevation.

Answer:
Jet stream
Explanation:
Jet stream is fast moving air or wind that blows horizontally through the upper layers of the troposphere, generally from west to east. It develops where air masses of different temperatures meet. The greater the difference in temperature, the faster the wind speed.
Jet stream has the following characteristics;
- The winds blow from west to east
- The flow often shifts to the north and south.
- They follow the boundaries between hot and cold air.
