Why is the distance between Europe and North America slowly increasing each year?

Answers

Becasue seafloors are slowly shifting apart which is causing continents to move.

In the 1960s, Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego and Harold Hammond Hess of Princeton University. They developed the theory that the seabed itself moves and carries the continents along with it as it extends from a central rift axis. Nowadays, the phenomena are referred to as plate tectonics.

What affect distance between Europe and North America?

When two tectonic plates diverge, a diverging border is created. As magma (molten rock) rises from the Earth's mantle to the surface and solidifies to form new oceanic crust, earthquakes frequently occur along these borders. Divergent plate boundaries can be seen, for instance, in the Mid-Atlantic Ridge.

A geologic process known as seafloor spreading involves the separation of tectonic plates, which are sizable chunks of the lithosphere of the Earth. Earth's mantle is slowly churning in a process known as mantle convection.

Therefore, because continents are moving as a result of the gradual separation of seafloors.

How to choose a college?

College should include safety, campus life, academic support and career services.

College is different from high school, because they demand a deeper level of understanding, college courses' research projects and assignments are different from those given to younger high school students.

It matters which college you attend because they all have distinct educational standards.

Additionally, it depends on the discipline and specialization that the potential student plans to follow. For instance, a student studying surgical surgery will likely have greater luck being accepted to prestigious medical schools.
