Answer 1

The main source of crude oil in Alaska is onshore drilling. Most of the crude oil produced in Alaska comes from the North Slope region, where oil is extracted from underground reservoirs through onshore drilling operations.

A generator is a device that converts mechanical energy into electrical energy by using the electromagnetic theory. It does this by rotating a coil of wire within a magnetic field, which induces an electric current in the wire.

Many modern tractors use GPS systems to steer up and down the fields without skipping any rows. GPS technology allows farmers to precisely map their fields and program their tractors to follow specific paths, ensuring that no rows are missed and that the land is used efficiently.

Coal-burning power plants are harmful to the environment for several reasons. They produce high amounts of carbon dioxide and other greenhouse gases, release tons of air pollution, and contribute to acid rain. Therefore, the correct answer is d) All of the above.
