Dr. Moore and his team have learned from GPS data that two continents with an ocean between them have been moving toward each other. Some students living on the coast of one of these continents don't understand what is happening and they are worried that the continents will run into each other. How could Dr. Moore explain to them what is happening?

Dr. Moore can explain that this is a continental drift process and that it is an extremely slow process and therefore no one should be concerned.

Explanation:

Continental drift is a geographic phenomenon that allows continents to move and "walk" towards each other. It is true that this can make the continents shock and cause a great catastrophe that would make human life rich, but there is no need to worry. This is because this movement is extremely slow and would take thousands of years for the continents to collide.

answer:

d. because dr. laguardia selected a widely used measure, his study generalizes to has strong external validity. external validity has limited external validity. other applications of this measure.

the widely used measure that he applied to his experiment was the benton facial recognition test. it employed on to football players and as result, only players who suffered brain concussions did not pas this test. and although it has an external validity, it is limited because it isn't general to apply to other population.
