Question:

What is the optimal relationship between supply and demand in order for the economy to expand?

Jay K.
Answer:

The supply of goods should meet demand as long as the demand, and the willingness to pay or trade a certain amount of something for the goods, is strong enough to balance the costs of producing the goods while providing for economic expansion (profits).

Earth Science

Question:

What are the basic elements of the hydrologic cycle?

Jay K.
Answer:

The hydrologic cycle involves the movement of water within the Earth System. Water on the Earth's surface enters the atmosphere via evaporation and transpiration (from plants). As the water vapor cools condensation occurs forming clouds. Eventually, clouds become saturated and can no longer hold the condensed moisture resulting in precipitation. The precipitation enters lakes, streams, and oceans and the cycle continues.
