A layer of liquid water may be present at the boundary between the mantle and the core.

A layer of liquid water (ocean) rich in dissolved ammonia may have formed at the core mantle boundary.

And the first paper is a standard scientific paper presenting evidence, Iridium Layer at the K T Boundary,

Structure Earth The Earth's atmosphere consists, from the ground up, of the troposphere (which includes the planetary boundary layer or peplosphere as lowest layer), stratosphere (which includes the ozone layer), mesosphere, thermosphere (which contains the ionosphere), exosphere and also the magnetosphere.

Iridium layer at the K T boundary, and potassium argon dated crater in Yucatan, indicate that an asteroid killed the dinosaurs.

There's an outer layer and an inner layer.

The main evidence of such an impact, besides the crater itself, is contained in a thin layer of clay present in the K Pg boundary across the world.

And that data, layer by layer, gets passed through the machine, starting at the base of the product and depositing material, layer upon layer, infusing the new layer of materials to the old layer in an additive process.

This solution involves solving the Cube layer by layer, in which one layer (designated the top) is solved first, followed by the middle layer, and then the final and bottom layer.

Layer after layer of legend, sport, details that resonate.
