Answer:
2. they claimed vast areas of land for Spain.
4.they brought much financial gain to Spain.
Step-by-step explanation:
The Spaniards explored and colonized the territory north of Mexico's current border with the US, between 1513 and 1776. For more than 250 years they formed more or less numerous expeditions for such a venture and paid a high cost in human lives, especially because of the hostility they found among the native tribes. The difficulty of the terrain, adverse weather on many occasions and great distances also contributed to this. Despite all this, the constant effort and the great courage of the explorers paid off.
All the south of the United States, the current states of California, Arizona, New Mexico, Texas, Louisiana and Florida, were part of the Viceroyalty of New Spain until well into the nineteenth century. This Viceroyalty extended its borders to much further north, through various settlements and forts along the entire Pacific coast and the center of the United States, settlements that were founded by sailors, explorers and adventurers throughout the eighteenth century and that reached the very Alaska where they came across the Russian Empire and English expansionist interests. The current locations of Valdez and Cordova in Alaska or the Canadian islands of San Juan, Lopez, Fidalgo or Cortes, are a small sample of the survival of a large number of Spanish place names on the north Pacific coast.
