The correct options are:
- Improved engines; engines were improved significantly so that they can have the same power and agility but by using less fuel.
- Cleaner burning fuels; it has been invested a lot of time and money into improving the fuels and making them as effective as possible but also removing or lowering the most dangerous components towards the environment.
- Catalytic converters; this devices for exhaust emission control manage to convert the toxic gasses and polutants into less toxic pollutants by managing to catalyze a redox reaction.
Answer:
The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent
Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.

1:Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges<span>. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.
2:</span><span>In areas where the </span>plates<span> come together, sometimes volcanoes </span>will<span> form. Volcanoes</span>can<span> also form in the middle of a </span>plate<span>, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian </span>Islands<span> were </span>formed<span> by such a hot spot occurring in the middle of the Pacific </span>Plate<span>.
