<span>The mountains were once seas. The land was forced up by tectonic motion when the mountains were formed. The Sahara also used to be a sea and has a valley full of the fossilized remains of an extinct species of whale. It is generally agreed upon that two plates colliding caused the uplift that created the mountainous zone. Same for the Himalayas.</span>

Narwhal population since 1970??? please provide websites found. If not, why can't I find any information on narwhal populations?

Narwhal population is increasing exponentially since 1970, due to some factors like increasing Birth rate, immigration etc.

If you are looking for website, then you should find for wider topic like search for Narwhal only instead of it's population/growth

Hope this helps!
