According to plate tectonics great Himalayas formed when
Europe collided with Africa
Asia 'ran' into India
South America collided with Antartica
Laurasia collided with Gondwana land
The radius of the core of the Earth is about
3500 kms
4500 kms
5300 kms
4450 kms
The temperature within the Earth increases with depth at rate of
10c for every 23m of depth
30c for every 32m of depth
0.10c for every 32m of depth
10c for every 32m of depth
The boundary between crust and Mantle of the Earth is called
Gutenberg Discontinuity
Mid Atlantic Ridge
Mohorovicic Discontinuity
SIAL
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
The formation of mountains are the result of
Divergent boundaries
Convergent boundaries
Transform fault boundaries
Earth quakes
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
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
The density of the core is
3.7 gm/cm3 at the centre
5.5 gm/cm3 at the centre
3.0 gm/cm3 at the centre
13.0 gm/cm3 at the centre
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.
