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
Density of the mantle varies between
3.0 gm/cm3 and 3.7 gm/cm3
5.5 gm/cm3 and 5.0 gm/cm3
3.3 gm/cm3 and 5.5 gm/cm3
3.0 gm/cm3 and 5.5 gm/cm3
The boundary between crust and Mantle of the Earth is called

According to plate tectonic theory, soild lithosphere consists of about
16 to 20 great slabs of rock
15 to 19 great slabs of rock
10 to 20 great slabs of rock
6 to 10 great slabs of rock
The average density of SIMA layer is about
5.3 gm/cm3
35 gm/cm3
3.0 gm/cm3

The main theories that explain the plate movement are
Gravity and Velocity
Velocity and convection
Conduction and Gravity
Gravity and convection
Based on the type of plate movement there are
6 types of plate boundaries
3 types of plate boundaries
2 types of plate boundaries
5 types of plate boundaries
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 copper Mantle is in
Solid state
liquid state
Partially molten state
Molten state
