The correct answer is the crust.
The crust is present above the mantle and is the hard outer shell of the Earth. The crust is 0 to 32 km in thickness. The densest type of crust is oceanic crust with the density of 3.0 g/cm3. The mantle is the layer below the crust and above the core.
The mantle exhibits an average density of 4.5 g/cm3. The density increases with depth as the pressure increases. The outer core exhibits a density between the range of 10 g/cm3 to 12.3 g per cm3 and the density of the inner core is about 12 g/cm3. Showing that the inner core exhibits the highest pressure.
Answer:
Ice cores drawn from Antarctica, Greenland, and tropical mountain glaciers proves that Earth's climate responds to changes in greenhouse gas levels. You can also find ANCIENT evidence in tree rings, coral reefs, layers of sedimentary rocks, and ocean sediments.

Explanation:
I learned about this already, and had to do deep research when I did.
A fossil will most likely be found in a sedimentary rock.
Explanation:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.
Cetaceans are fully aquatic marine mammals belonging to the order Artiodactyla, and branched off from other artiodactyls around 50 mya (million years ago). Cetaceans are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with hippopotamuses.
