How are subduction zones related to megathrust earthquakes

Answers

Answer:

Subduction zone megathrust faults host Earth’s largest earthquakes, along with multitudes of smaller events that contribute to plate convergence. An understanding of the faulting behavior of megathrusts is central to seismic and tsunami hazard assessment around subduction zone margins. Cumulative sliding displacement across each megathrust, which extends from the trench to the downdip transition to interplate ductile deformation, is accommodated by a combination of rapid stick-slip earthquakes, episodic slow-slip events, and quasi-static creep. Megathrust faults have heterogeneous frictional properties that contribute to earthquake diversity, which is considered here in terms of regional variations in maximum recorded magnitudes, Gutenberg-Richter b values, earthquake productivity, and cumulative seismic moment depth distributions for the major subduction zones. Great earthquakes on megathrusts occur in irregular cycles of interseismic strain accumulation, foreshock activity, main-shock rupture, postseismic slip, viscoelastic relaxation, and fault healing, with all stages now being captured by geophysical monitoring. Observations of depth-dependent radiation characteristics, large earthquake slip distributions, variations in rupture velocities, radiated energy and stress drop, and relationships to aftershock distributions and afterslip are discussed. Seismic sequences for very large events have some degree of regularity within subduction zone segments, but this can be complicated by supercycles of intermittent huge ruptures that traverse segment boundaries. Factors influencing variability of large megathrust ruptures, such as large-scale plate structure and kinematics, presence of sediments and fluids, lower-plate bathymetric roughness, and upper-plate structure, are discussed. The diversity of megathrust failure processes presents a suite of natural hazards, including earthquake shaking, submarine slumping, and tsunami generation. Improved monitoring of the offshore environment is needed to better quantify and mitigate the threats posed by megathrust earthquakes globally.

How are chemical reactions used in art​

Answers

Answer:

Chemistry reactions are used in art for the following processes;

1) Analog photography

The photographic paper used in analog photography react when exposed to light such that the image on the film stains the photopaper

A series of chemicals are further used to develop the images now carried on the paper and water is used to rinse of the chemicals after the other chemical processes are complete

The photopaper, now bearing the developed photo is hung for it to be dried

2) Paint used for painting consists of several chemicals, including, minerals that serve as pigment, oils that serve as carrying agent, a thinner to prevent the paint from turning to solid

An artist therefore combines different chemicals for a given paint task

3) In the sculpting process

An original sculpture is produced by the artist with the aid of clay or plaster, from the original sculpture, on which wax coatings and chemicals are used to make a replica mold.

Copies of the sculpture can then be made by pouring material into the mold

For the cold pack shown below, the temperature on the outside surface has dropped considerably from its initial temperature of 25 °C. Which of the following provides the best explanation for this temperature decrease?

Answers

Answer:

The correct answer is D

Explanation:

In an endothermic process, energy travels from the surroundings into the system. The decrease in the temperature on the outside of the bag indicates that energy has moved from the surroundings into the system.

The other answers are incorrect. A bag cannot release “cold” into the surroundings since cold refers to the absence of heat. The surroundings become colder when heat is removed. Option B is incorrect because the cooling is due to the cold pack absorbing heat energy from its surroundings. Option C is incorrect because a cold pack absorbs heat energy from the surroundings, not vice versa.

The surroundings are losing energy and the thermometer is measuring the temperature of the surroundings as the cold pack shows an endothermic process. Therefore, Option (D) is correct.

What is an endothermic reaction?

Endothermic reactions are those in which the reactants absorb heat energy from their surroundings to form products. Endothermic reactions reduce the temperature of their surroundings and create a cooling effect. Physical processes can be endothermic in nature as well, for example, ice cubes absorb heat from their surroundings to form liquid water.

Endothermic reactions include the making of chemical bonds through the absorption of energy from the surroundings. On the other hand, exothermic reactions are in which the liberation of heat energy is generated from bond breakage.

The temperature of the cold pack is lower than the temperature of the surroundings. So the heat energy will be traveled from the surroundings to the cold pack.

Therefore, the temperature of the surroundings will fall as heat transfers to the cold pack.

A delivery truck hits a parked car from behind. The mass of the car is 2550 kg. What force is exerted on the car if (a) the car is rigid and accelerates to 4.5 m/s in 0.20 s? (b) the car has crumple zones and accelerates to 4.5 m/s in 0.30 s?
Helpp meee........TT​

Answers

Explanation:

Given parameters:

Mass of the car  = 2550kg

Initial velocity  = 0m/s

Solution:

First problem is to find the force exerted on the car;

  Velocity  = 4.5m/s

   Time  = 0.2s

Acceleration  = [tex]\frac{final velocity - initial velocity }{time}[/tex]   = [tex]\frac{4.5 - 0}{0.2}[/tex]  = 22.5m/s²  

Force  = mass x acceleration  = 2550 x 22.5  = 57375N

B. Force on the car with crumple zones

Acceleration  = [tex]\frac{final velocity - initial velocity }{time}[/tex]    = [tex]\frac{4.5 - 0}{0.3}[/tex]   = 15m/s²

 Force  = 2550 x 15  = 38250N

a. The force when the car is rigid and accelerated is 57375N.

b. The force where the car should have  crumple zones should be 38250N

Calculation of the force:

Since Mass of the car  = 2550kg

Initial velocity  = 0m/s

Here,

Velocity  = 4.5m/s

Time  = 0.2s

a.

Here force = mass * acceleration

= 2550 * (4.5 - 0/0.2)

= 2550 * 22.5

= 57375 N

b.

Here force is

= mass * acceleration

= 2550 * (4.5 - 0/0.3)

= 2550 * 15

= 38250 N

Explain why noble gases cannot participate in ionic bond formation.​

Answers

Explanation:

Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. So, noble gases cannot participate in ionic bond formation.

Answer:

Because they can't!

Explanation:

For ionic bonds, ions are needed to be made which are made to form a stable outer shell octet of electrons of each atom to gain atomic stability. The noble gases don't need to form ions since they already have the octet of electrons in their outer shells. If they don't form ions, they don't form ionic bonds too.

This is one of the reasons why noble gases are unreactive.
