ANSWER:

Peru and Ecuador both export cash crops from plantation.

EXPLANATION:

Cash crop is defined as a crop which is produced or generated for industrial purpose. These crops are not used for personal use. Cash crop also has its own characteristics and properties. The crop needs certain atmosphere to grow in a large production rate. These cash crop is suitable at the region of mild temperature where loads of cereal, oil-yielding crops, vegetables, tree and fruits are the production that can be done in large scale.

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.
