Geography
1 answer:
Paul [167]2 years ago
6 0

Answer:

Let's take a look at the modern day headphones we have now. They're airpods. Wirless. It used to be connected to wires. And those earbuds used to be headphones. And those headphones used to be heavy speakers.

Explanation:

How did they evolve with growth in technology? Back in the early 1890s, headphones were single-sided, heavy speakers that people would hold on to an ear to communicate. This later evolved into something known as an 'Electrophone'. It was a system consisting of a stethoscope-shaped headphone connected to a switchboard.

We started using them in the wars to communicate with the troops on the ground and now we use them to stay focused, to disappear and to give ourselves some time away from the stressful world we live in.

Examining sedimentary bedding (layers of rock or sediment) in a geologic study reveals disrupted layers formed 260, 820, 1,200,
Dmitriy789 [7]

Answer:

510

Explanation:

Recurrence interval involves the average estimated time or average spacing between events. It helps to estimate the time probability of an event taking place.

Calculating the recurrence interval we have:

[(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4

= (560 + 380 + 900 + 200) / 4

= 2040/4 = 510

After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.
