Answer 2

the correct pair is (c)Asthenosphere -the origin of convection current

• it is derived from the greek word meaning without strength

• it is the upper part of the mantle
• it is a highly viscous weak layer  
• it lies beneath the lithosphere by a depth of 80-200 km
• all the tectonic plates float over this layer.
• it is one  of the most unstable layer composed of viscous gases and fluid compressed under the weight of the crust.
• convection currents originate from this layer.
