Trade involves the buying and selling of goods and services between parties, with the buyer compensating the seller. It can be classified as either internal trade, which occurs within a country, or external trade, which crosses geographic boundaries. Trade is important because it allows countries to obtain resources they lack by exchanging surplus goods and fulfilling each other's needs. Key transportation methods for trade include roads, railways, air routes, and sea routes using vehicles like trucks, trains, airplanes, and oil tankers. An oil terminal stores oil and petrochemical products and transports them to end users or further storage, while an oil tanker is a specialized cargo ship that transports refined oil products between countries via sea routes.
