From the colonial era to today, immigration to the United States has changed and developed in distinct phases or "waves." A. For each of the time periods below, describe the major wave of immigration to the US that occurred and identify the continents or regions sending migrants.

1609–1775

1820–1920

1950–present

B. Within the second and third waves (1820–1920 and 1950–present), smaller waves of immigration occurred as migration sharply increased from particular countries or regions.

Provide examples of at least two of these subphases for each time period. Identify the countries or regions sending migrants and give examples of the push or pull factors driving migration.

C. Changes in circumstance can greatly affect push and pull factors. Provide two examples of changes to push and pull factors that caused waves of migration to begin or end. Make a connection to historical examples for each.

1) earth's crust is made up of relatively rigid plates that ride atop earth's hot, semiliquid mantle. (2) the plates are called tectonic because they're in constant motion. (3) they can move because earth's mantle is a very hot and semiliquid fluid called magma. (4) volcanoes are a result of magma rising up or erupting through a plate, particularly where plate boundaries are moving against each other. (5) also, when plates slide against each other, causing friction along adjacent plate boundaries, earthquakes frequently occur. (6) therefore, we often find volcanoes and earthquakes along plate boundaries. (7) plates may also collide. (8) when that happens, mountain ranges are formed. (9) for example, the collision of the plate carrying the indian subcontinent created the himalayan mountains when it collided with the asian plate. 2. which sentence in this passage introduces a new topic that might begin a new paragraph? a. sentence 5 b. sentence 4 c. sentence 7 d. sentence 6
