<h2>Answer:</h2>
B.lithosphere is neither destroyed nor produced
<h2>Explanation:</h2>
Transform boundaries are places where plates slide sideways past each other. One plate is forced below another in a process which is called subduction. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. In this process, lithosphere is neither created nor destroyed so B is the correct option.
An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.
<h3>What kind of respirator offers a separate source of clean air?</h3>
For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.
<h3>What 2 categories of respirators exist?</h3>
Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.
<h3>When should you use an air purifying respirator?</h3>
a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%

Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:
Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
Answer:
A magnetic storm is a period of rapid magnetic field variation. It can last from ... When these events occur, we can experience a truly large magnetic storm
Explanation:
Digestion and Absorption
Mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
