At which point does the motion of convention currents occur to drive plate movement
OLEGan [10]

<u>Answer</u>: 2

The convection currents shown in points 1 and 3 transfer heat from the outer core (number 4) to the lithosphere. Here, the lower density hot magma breaks apart the plates at <em>point 2</em> creating a divergent plate boundary. <u>This new magma mass will drive a lateral movement of the plates</u>. The edges of the plates which have a higher density basalt rock will sink into the mantle and get consumed in trenches/subduction zones

When the temperature of the body enhances, the sweat glands along with water also discharges electrolytes from the surface of the body.  

The sweat glands also exhibit antibacterial properties, as they discharge dermcidin that interferes with the sticking of the microbes with the skin surface. The exocrine sweat glands do not secrete lipids, thus, they lack the tendency to condition the skin surrounding it. Hence, the given statement 3 is incorrect.
