Continental drift is the geological phenomenon in which continents move. These movements at speeds of a few centimeters per year can actually be measured since the advent of satellite geodesy. The movement of continents is caused by plate tectonics.
Alfred Wegener noted at the beginning of the 20th century that the edges of some continents (particularly South America and Africa) are similar in shape, concluding that the continents were connected and separated before. The problem was that it was not known how huge land masses could move across the Earth's surface. Such a movement requires enormous power and it was not known where it came from.
Later it was known that, according to plate tectonics, the continents move as a result of convection currents in the mantle. They slowly move away from each other, bump into each other, slide under each other, or rub against each other. This causes various surface phenomena, such as earthquakes, volcanism, and slow changes, such as subsidence, mountain building and the displacement of continents.

Answer:
Perceptual set
Explanation:
Perceptual set: perceptual set is the phenomena that describe a tendency to notice the presented sensory data or objects and ignore others.
The perceptual set work on two concepts:
- The perceive has some expectation that there is some stimulus and pay attention to these to these perceptual data.
- The second one in which the perceive knows what the name to be given to the data or an object. What are inferences drawn from the data?
The perceptual set has the number of factors that influence perceptual set:
