Oil is mined using high-tech equipment that drills into the earth's crust.
A tanker spills oil in a canal. When an oil deposit is discovered, oil is pumped upwards to the earth's surface. In the United States, Texas, Alaska and California are the top three oil producers. Although oil is found in other states, our country produces only about half what we need because we have become so dependent on oil for heat, fuel and all the other products made from it. We use ships called oil tankers to carry the product back and forth.
