Question 1 of 5
 

An oil tanker, also known as a petroleum tanker, is a merchant ship designed for the bulk transport of oil. There are two basic types of oil tankers: the crude tanker and the product tanker. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move petrochemicals from refineries to points near consuming markets.


What is the primary difference between crude tankers and product tankers?

The product tanker carries refined oil products while the crude tanker carries unrefined oil.
The product tanker is small while the crude tanker is large.
The product tanker carries consumer goods while the crude tanker carries industrial goods.
The product tanker carries oil to refineries while the crude tanker carries oil from refineries.
