Which type of crust combination CANNOT undergo subduction?

Chemistry

nordsb [41]3 years ago
6 0

Answer:

the correct answer is B

Explanation:

Subduction: they present if or if two Convergent edges or subduction zones (destructive edges). Where two plates collide, due to having movements with opposite directions, the denser one sinks below the less dense one along what is known as the subduction zone; the subducting plate goes into the mantle, heating up and partially melting generating magma that rises to the surface. A subduction zone is characterized by deformation, volcanism, mountain formation, metamorphism, seismic activity, and significant mineral deposits.

This phenomenon occurs between oceanic plates or between a continental and an oceanic plate, since when there is a difference in density they subduct.

In the event that the edges of two continental plates collide, it would be OBDUCTION, which is another phenomenon other than subduction. mantle does not produce the correct subduction process, as the movement must be absorbed in some way, this is carried out by vertically deforming both plates, which are joined by a suture area, forming an inner mountainous belt and Suffering, in addition, numerous earthquakes. This process is very important, since it is the one that has given rise to the highest mountain ranges on Earth and is a very active process at present (Ex: Los Alpes, Los Montes Urales and Montes Himalaya).

How would you separate a mixture of water, sand, salt and iron filings into its four component parts
kipiarov [429]
Magnet to remove the iron, filter paper (or some filter that could trap sand) to remove the sand, and heat up the salt and water, causing the water to evaporate to separate them.

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 mi
nadezda [96]

Answer:

A)You must work 2 shifts to wash 10 loads of laundry

B)You can wash 15 loads pf laundry if you work for 3 shifts

C) each shift will pay for 3.75 loads of laundry if the cost per load rises to 16 quarters

Explanation:

Given:

amount  earned =   12 dollars/hour

Duration for one shift = 75 minutes

Amount needed for Laundry = 12 quarters/load.

A. How many shifts must you work if you wish to wash 10 loads of laundry

To wash 10 loads, you will be requiring

=> 10 \times 12 \text{quarters}

=> 120 quarters

1 quarter = 0.25 dollars---------------------------------(1)

120 quarters

= 120 \times 0.25 \text{ dollars}

= 30 dollars

You need 30 dollars for washing 10 loads

In one hour i,e 60 minutes you earn=  12 dollars

In one minute the amount earned will be

= \frac {12}{60}

= 0.2 dollar-------------------------------------------------------(2)

Now to earn 30 dollars you have to work for

=30 \times 0.2 minutes

= 150 minutes

Thus the number of shifts will be  

= \frac{150}{75}

= 2 shifts

B. How many loads of laundry can you wash if you work 3 shifts

We Know that 1 shift =  75 minutes

So 3 shifts = 75 \times 3 = 225 minutes

From (2),

In 1 minute = 0.2 dollars is earned

So in  225 minutes =  225 \ times 0.2 = 45 dollar is earned

45 dollar = 45 \times 4 = 180 quarters

You can wash 1 load with 12 quarters

With 180 quarters you can wash = \frac{180}{12} = 15 loads

C. How many loads of laundry will each shift pay for if the cost per load rises to 16 quarters

Cost per load = 16 quarters

From (1)

16 quarters = 0.25 \times 16  = 4 dollars per load

From (2) In 1 shift the amount earned will be

=> 75 \times 0.2

=15 dollars

With 4 dollars you can wash 1 load

So with 15 dollars = \frac{15}{4} = 3.75 loads
