7. Which statement correctly describes the density of Earth's mantle compared to the density of Earth's
core and crust?

1) The mantle is less dense than the core but more dense than the crust.

2) The mantle is less dense than both the core and the crust.

3) The mantle is more dense than the core but less dense than the crust.

4) The mantle is more dense than both the core and the crust.

Answer:

1) the mantle is less dense than the core but more dense than the crust.

The mantle is less dense than the core but more dense than the crust.

The Earth's crust is the outermost shell of the planet.

The Earth's mantle is bounded below by the core and above by the crust.

  • The density of the upper mantle of the Earth is given as 3.4 g/cm³.
  • The density of the lower mantle of the Earth is given as 4.4 g/cm³.
  • The density of Earth's core (inner and outer core) is between 9.9 and 12.2 g/cm³.
  • The density of the Earth's crust is 2.6 g/cm³

Thus, we can conclude that the mantle is less dense than the core but more dense than the crust.
