Electrical pressure, called "electro-motive force" (EMF), is what causes current <span>to flow in an electrical circuit. EMF is measured in volts. Pressure and the </span><span>quantity of electricity transmitted can be considered analogous to pressure and </span><span>quantity of water flowing in pipes: the longer the distance, the higher is the </span><span>flow of water (called the "flow of electrical charge, which is also known as the </span><span>"electric current"). That is why, for long distance transmission, high pressure </span><span>(voltage for electricity) is required, failing which, the current - and </span><span>therefore the power - will not reach the intended destination. Instead, it will </span><span>be lost (also called "dissipate") along the way. We can think of electrical </span><span>current as the quantity of electricity which will be drawn from the pipeline </span><span>
cables for electricity) at the pressure (= voltage) required.

Answer: Alfred Wegener provided some of the important points that supported the theory of continental drift. They are as follows-
The continents were once all attached together, and this can be proved by studying the coastlines of some of the continents that perfectly matches with one another.
The appearance of similar rock types and similar fossils (including both animals and plants) has also contributed much information that continents were once all together.
