No, the heaviest materials are not located at the Earth's surface. Instead, denser materials, such as iron and nickel, are found in the Earth's core, while lighter materials, like silicates, are found in the crust. This differentiation in density is due to the process of gravitational differentiation that occurred during the formation of the Earth. Thus, the heaviest elements are concentrated toward the center, not the outside.

The heaviest sediment is generally composed of materials such as gravel, sand, and silt. These sediments have higher densities and larger particle sizes compared to lighter sediments like clay. Heavy sediments are typically found closer to their source of origin due to their weight.

The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
The least dense element is hydrogen hence it would be the lightest thing with mass. However there are 'massless' particles, such as photons.
Hydrogen is the lightest gas found in air.

Mercury is the heaviest element at a liquid state.
If you are talking about element sin the periodic table, it is ununoctium(Uuo)

The heaviest parrot in the world is the Kakapo, which is only found in New Zealand.
