When vapor pressure equals atmospheric pressure, it's called boiling point of that liquid.
The oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.
<h3>What is the lithosphere?</h3>
The lithosphere can be defined as the outer rock layer present on the Earth's surface.
The oceanic lithosphere is composed of different rocks of the mantle such as, among others, gabbro and/or basalt.
The structure of the oceanic lithosphere is similar around the world because it is slender compared to the continental lithosphere and always determined by the supply of magma.
In conclusion, the oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.

To solve this problem we will use the Ampere-Maxwell law, which describes the magnetic fields that result from a transmitter wire or loop in electromagnetic surveys. According to Ampere-Maxwell law:

Where,
B= Magnetic Field
l = length
= Vacuum permeability
= Vacuum permittivity
Since the change in length (dl) by which the magnetic field moves is equivalent to the perimeter of the circumference and that the electric flow is the rate of change of the electric field by the area, we have to

Recall that the speed of light is equivalent to

Then replacing,


Our values are given as




Replacing we have,



Therefore the magnetic field around this circular area is 
Answer:
Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond. This is because each nitrogen atom has 5 valence electrons. Each atom can complete its octet by sharing three electrons.
I hope this helps!
