The Columbian exchange was a product of European overseas expansion (a series of interactions and adaptations among societies across the Atlantic). Exploration and conquest by the Spanish and Portuguese resulted in extensive fatal epidemics, the creation of racially mixed populations, and the establishment of a caste system.
Spanish settlers had a significant impact on the Western Hemisphere's economic, social, and political growth exchange through the introduction of new crops and cattle. New American crops encouraged population growth in European countries.
The European transition from feudalism to capitalism was made easier by new mineral income exchange sources. The British colonies in North America supplied Europe with raw goods including rice, tobacco, and lumber.

Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.
<h3>Which discontinuities are caused during welding?</h3>
Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.
