Which example gives the relative location of a place? 50 main street 33 degrees n latitude, 91degrees w longitude east of the library 1600 pennsylvania ave., washington, d. c.

The example 'east of the library' gives the relative location of a place.

Explanation:

A relative location of the place is the one which is described with a reference to a nearby landmark. The landmark serves as a place of common prominence for all the nearby locations. For example, when a place is said to be located at a certain point to the west of the Empire States Building, the Empire States Building is the landmark of reference. The location of the place is relative to this reference landmark and is thus called 'relative location'.

The second one is the answer edg.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
