Answer:
sorry if its too big.
Explanation:
U.S. immigration has occurred in waves, with peaks followed by troughs (see figure). The first wave of immigrants, mostly English-speakers from the British Isles, arrived before records were kept beginning in 1820. The second wave, dominated by Irish and German Catholics in the 1840s and 1850s, challenged the dominance of the Protestant church and led to a backlash against Catholics, defused only when the Civil War practically stopped immigration in the 1860s.
The third wave, between 1880 and 1914, brought over 20 million European immigrants to the United States, an average of 650,000 a year at a time when the United States had 75 million residents. Most southern and eastern European immigrants arriving via New York’s Ellis Island found factory jobs in Northeastern and Midwestern cities. Third-wave European immigration was slowed first by World War I and then by numerical quotas in the 1920s.
Between the 1920s and 1960s, immigration paused. Immigration was low during the Depression of the 1930s, and in some years more people left the United States than arrived. Immigration rose after World War II ended, as veterans returned with European spouses and Europeans migrated. The fourth wave began after 1965, and has been marked by rising numbers of immigrants from Latin America and Asia. The United States admitted an average 250,000 immigrants a year in the 1950s, 330,000 in the 1960s, 450,000 in the 1970s, 735,000 in the 1980s, and over 1 million a year since the 1990s.
The closest star to the sun, Proxima Centauri, was recently found to have a planet in its habitable zone. Proxima Centauri is a main sequence star with spectral type m. It would habitable zone differs from the habitable zone of our sun Compared to our own, it would be far closer to Proxima Centauri.
<h3>What is the Proxima Centauri? </h3>
- Small, low-mass Proxima Centauri is a star in the southern constellation of Centaurus, 4.2465 light-years from the Sun.
- Its Latin name translates to "star closest to Centaurus."
- It is the known star that is closest to the Sun and was found in 1915 by Robert Innes.
<h3>Is the planet Proxima Centauri one?</h3>
- Super-Earth-sized exoplanet Proxima Centauri b revolves around a M-type star.
- It has a mass of 1.27 Earths, orbits its star in 11.2 days, and is 0.0485 AU away from it. In 2016, news of its finding was released.

The correct answer is a plateau<span>. A plateau is a flat, elevated land form that rises sharply above the surrounding area on at least one side. It occurs on every continent and take up a third of the Earth's land. Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it. </span>
They are believed to cause divergence of lithospheric plates at the <span>mid atlantic ridge
</span><span> The currents reallocate heat from a certain place to another through mass motion of fluid (such as molten rock or water), The difference in temperature between core and lithosphere material generate enough force for the divergence to happen.</span>
