The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.

If another predator, that is more efficient hunter, enters the territory of the puffins, the puffins will find themselves in a very tough situation. They will either have to adapt very quickly, or die out.
The evolutionary pressure will be there fro the puffins to push them in a direction to adapt and be netter hunters, thus fight for their existence. That would mean that the puffin's beak, but also their speed and efficiency will have to improve in order to compete or even out-compete the new predator.
If the puffins do not manage to adapt relatively quickly, and a food shortage occurs, than they will die out, as they will lose the fight for food constantly.
