The Urals were formed during the Carboniferous period when the continents all came together to make the supercontinent Pangea. The present day Northern Hemisphere landmasses moved towards the equator to form Laurasia and to join the large Southern Hemisphere landmass Gondwana. The collision between Siberia and Eastern Europe created the Ural Mountains. The Carboniferous period was between 290 and 350 million years ago, so the Urals are quite old and have had a long time to be eroded down. Prior to the collision both sides of the plates which collided would have been coastal.

By comparison the Himalayas started forming just 18 million years ago when the Indian plate collided with Eurasian plate. The Indian plate is still pushing northward and the Himalayas will continue to grow. Once again prior to the collision both sides were coastal, as shown by the presence of marine fossils high in the Himalayas.

Of course some people have their own theories, as covered in the third link. Personally I think the plate tectonics theory is much more solidly based.
