Along the Juan de Fuca Ridge, volcanoes produce oceanic crust. The Juan de Fuca Plate cools, grows denser, and finally sinks beneath the less dense North American Plate at the Cascadia Trench as it wanders eastward.
<h3>Is the Juan de Fuca Plate dying?</h3>
Because the decaying Juan de Fuca plate is not sinking silently, scientists have a unique opportunity to investigate such impacts. They are intently observing the system's every tremble and burp. (We learned that a strong earthquake broke a tectonic plate in half in this way.)
<h3>How Fast Is Juan de Fuca moving?</h3>
The Farallon Plate, a much bigger oceanic plate that originally existed alongside the smaller Juan De Fuca Plate, is moving east-northeast at a rate of 4 cm (1.6 inches) each year.
<h3>What is happening between the Gorda Plate and the Pacific Plate?</h3>
At a rate of 5 cm per year, the Pacific Plate is diverging from the Gorda Plate as it moves in a northwesterly direction. At a much slower rate of 2.5 to 3 cm per year, the Juan de Fuca Plate (which includes the Gorda Plate) is subducting beneath the North America Plate.

The correct answer is - from rural to urban areas.
With the economic development that China has been experiencing in the past few decades, lot of things changed in the country. The large cities became even larger, modernized, all sorts of industries developed in them, the wages became higher, and much more opportunities for the people have been opened up. This has led to a mass migration of the Chinese workers from the rural areas to the urban areas. The rural areas did not experienced such development as the urban areas, so in order to have better living conditions and better jobs, millions of Chinese workers moved from the villages and small towns toward the large cities and megalopolises.
