Listening to Earth is an article about the study of the plate boundaries using hydrophones which make noises and different sounds.
<u>Explanation:</u>
Listening to Earth is an article which was written about the studying of the plate boundaries by Dziak and his team. Since it is tough to send people to the bottom surface of the ocean, they made use of hydrophones making them listen to various sounds.
These sounds are made by the movement and the motions of the plate boundaries from their original position which many a times lead to the earthquakes.
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
