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.
Wind erosion is a natural technique that actions soil from one place to some other by using wind energy. it may purpose enormous monetary and environmental damage.
Erosion through Water Liquid water is the essential agent of erosion in the world. Rain, rivers, floods, lakes, and the ocean convey away bits of soil and sand and slowly wash away the sediment. Rainfall produces four kinds of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Wind erosion is the bodily sporting of the earth's surface via wind. Wind erosion removes and redistributes soil. Small blowout areas may be related to adjoining regions of deposition at the base of plant life or behind barriers, including rocks, shrubs, fence rows, and road banks.

Answer:
<em>Natural causes of earthquakes </em>
Explanation:
Earthquakes are triggered<em> by the rapid energy release in some of the Earth's small rocks. Energy can be released by elastic stress, gravity, chemical reactions, or even massive body motion.</em>
The release of elastic strain is the most important cause of all these, because this form of energy is the only sort that can be stored in sufficient quantities on Earth to create major disruptions. This type of energy release related earthquakes is called tectonic earthquakes.
