The last dinosaur fossils were found in layer e.

which layer formed during the cenozoic era?

a.
b

b.
f

c.
c

The correct answer is: F

The Cenozoic era is the most modern era and F is above E which would make F younger then E.

D is not correct because it means E is older.

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
