Answer:
Explanation:
At constructive margins such the mid oceanic ridge where new magma are brought to the surface, evidences abounds to support the theory of continental drift through paleomaganetism.
Continental drift is simply the moving of the land masses on earth from their original positions.
There are certain magnetic minerals in rocks that are able to record the prevailing magnetic conditions in a particular terrane. In a hot magma, at the oceanic ridge for example, these minerals align to the magnetic direction at work during the period when they are cooling. As new materials upwells, the cool layer shifts away from the margin each bearing the paleomagnetic record.
Therefore, through a series of reversals and normality in the magnetic direction, one can deduce that the continents actually moves.

The correct answer is - No.
Winnipeg, Canada, is not further away from the Equator than Moscow, Russia, in fact Moscow is the city that is further away from the Equator. Moscow is on a latitude of 55.7558° North, while Winnipeg is on a latitude of 49.8951° North, thus putting Moscow by 5.8607° further away from the Equator than Winnipeg is.
