Choose the correct statement
The density and temperature increases with depth of Earth where as pressure decreases with depth.
The density, temperature, and pressure do not vary with the depth of Earth.
The density temperature and pressure increases with the depth of Earth
The temperature and pressure increases with the depth of Earth and density decreases with the depth
SIAL is in solid state, SIMA is in liquid state.
SIMA is less denser than SIAL
SIMA "floats" on SIAL
The lighter SIAL is considered as "floating" on denser SIMA layer.
The Gutenberg Discontinuity is
The boundary between the Mantle and the core
The boundary between crust and mantle
The boundary between inner core and outer core
The boundary between Bary Sphere and Mesosphere
