Question

which of the following layers consists gold ?

a) Crust
b) Mantle
c) Inner Core
d) Outer Core ​

Answer 1

Answer:

During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals -- such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.

Answer 2

Answer:

d) Outer Core ​

Explanation:

• The outer core and the inner core are the two layers that make up the Earth's core.
• The third layer of the Earth is its outer core. Iron and nickel, together with trace quantities of other materials, make up the majority of this layer, which is the only one that is liquid.
• The Earth's magnetic field is created by the outer core.
• The iron inside the liquid outer core of Earth flows about as it rotates on its axis.
• In the liquid iron itself, the movement creates strong electric currents.
• A magnetic field is produced by these strong currents, which extend lines of invisible force hundreds of kilometers into space and surrounding the Earth.
• The Earth is shielded by the magnetic field from dangerous particles that emanate from the sun.
• It is the layer that contains gold.
