Economic: Countries sought new sources of wealth and resources, such as gold, silver, and spices, which could be found in distant lands. Explorers were also sent to find new trade routes, which could increase a country's wealth and power.
Political: Countries used exploration as a way to expand their territory and influence. By exploring new lands, countries could claim them for their own and gain control over their resources. Exploration could also be used to weaken rivals by cutting off their access to resources or trade routes.
Religious: Some countries sent explorers to spread their religion to new lands. Missionaries often accompanied explorers, and they worked to convert the people they encountered to their faith.
Scientific: Some countries sent explorers to learn more about the world around them. Explorers made observations about the natural world, and they collected specimens of plants and animals to bring back to their home countries.
Technological: Exploration also led to the development of new technologies, such as the compass, the astrolabe, and the telescope. These technologies made it easier for explorers to navigate the oceans and find new lands.
