Mid-ocean ridges can be regarded as a process which do occur along divergent plate boundaries.
This occurrence do happen where new ocean floor is created when the Earth's tectonic plates spread apart.
- It should be noted that As the plates separate, there would be rise in molten rock.

Answer:
There are two primary scales used to measure earthquakes: the Richter scale and the Mercalli scale.
Explanation:
The Richter scale is most common in the United States, while worldwide, scientists rely on the Mercalli scale.
Answer:
Angle CBE = 48 degrees.
Explanation:
I'm doing the same math quiz right now and was pretty stumped. However, it was actually really easy once you think about it enough!
<em>Please make sure to reword my answer and remember as stated already at the beginning of the quiz, the angles are not drawn to scale.</em>
Step 1: Take the stuff that equals CBE, turn it into an equation, and solve.
<u>OPTIONAL</u>: Plug 18 for x into the equation and you'll get 132 = 132, making it a true answer.
Step 2: Plug 18 for x into the angle measurements.
ABD: 42 degrees (given)
DBE: 5(18) = 90 degrees
CBE: Take 180 and subtract both 42 and 90. You get 48 degrees, which is your final answer.
the person that helps out others even his/her enemy when in need is regarded as a good person.
