Okay kiddo, so let me explain to you what comarcas are in Spain. A comarca is like a big area in Spain that is made up of smaller towns and villages. It's kind of like a county in other countries, but in Spain, they use the term comarca instead.
Each comarca has its own unique culture, history, and customs. They also have their own local government, which helps make decisions about the area, such as building new roads or schools.
Some comarcas are very famous for certain things, like the comarca of La Rioja, which is known for its delicious wine. Others are known for their beautiful beaches or stunning mountains.
So basically, comarcas are like big areas in Spain, made up of lots of smaller towns and villages, each with their own unique culture and government. They help organize things in that area and make important decisions for the people who live there.
