Question

Which of the following best describes a benefit of one type of nonrenewable energy?

Natural gas does not produce greenhouse gases when it is burned.
Coal deposits are found on nearly every continent and mining coal poses few risks.
Petroleum is not carbon based and will not produce carbon dioxide as a byproduct.
Nuclear power does not produce air pollution as other energy sources do.

The majority of marine organisms are found in coastal regions, rather than the open ocean. Which of the following best explains why?

Ocean currents bring nutrient-rich water into coastal regions.
The shallow waters of coastal regions provide less oxygen.
Salinity is usually much higher in coastal regions.
Temperatures are cooler in coastal regions.

Answer 1

1. Nuclear power does not produce air pollution as other energy sources do.
2. Ocean currents bring nutrient-rich water into coastal regions.

Answer 2

Answers:

1. (D) Nuclear power does not produce air pollution as other energy sources do.

A non-renewable resource is a resource that seems not to renew itself at a satisfactory rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The primary organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas.

2. (A) Ocean currents bring nutrient-rich water into coastal regions.

Marine life, or sea life or ocean life, is the plants, animals and other organisms that exist in the salt water of the sea or ocean, or the brackish water of coastal liquids. At a basic level, marine life helps define the very nature of our planet. Marine organisms produce much of the oxygen we breathe.
