Geography

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.

Degger [83]

The enormous submarine canyon located off the coast of central California in Monterey bay is very well studied for both its geologic and biologic features, as well as being a national marine sanctuary. Thus, "Monterey" is the correct filler to be used here.

<h3>What is a Submarine canyon?</h3>

A submarine canyon is a steep-sided valley that has been dug into the seabed of the continental slope; it can occasionally extend deep over the continental shelf, have virtually vertical walls, and can have canyon walls that are up to 5 km high, like the Great Bahama Canyon. Submarine canyons provide routes for the movement of turbidity currents over the seafloor, just like above-sea level canyons do for the movement of water through land.

Rivers may provide turbidity currents or storms, and undersea landslides, earthquakes, and other soil disturbances may create them on the seafloor. Turbidity currents are movements of water that are thick and sediment-laden. The continental slope is eroded by the swift (up to 70 km/h) turbidity currents that flow downslope.

Answer:

The streets of downtown Laredo, Texas, are deserted. For decades, this dense retail district has catered to Mexican shoppers coming across the bridge from Nuevo Laredo. But these days, stores like Cindy's Electronics, Classic Perfumes, and Casa Raul Mens' Clothes are shuttered. "Now our business has dropped 80 to 90%," says Natividad Dominguez, leaning on a glass case full of empanadas, turnovers and donuts at Pano's Bakery. "People would come across the bridge and pick up a donut. But no more. It's affecting us a lot."
