Okay kiddo, let's talk geography of South Korea. South Korea is a country located on the southern half of the Korean Peninsula in East Asia. The Korean Peninsula is a landmass that sticks out of Asia like a big nose.
South Korea is surrounded by water on three sides: the East Sea (also known as the Sea of Japan) to the east, the Yellow Sea to the west, and the Korea Strait to the south. It's sort of like an island, but it's actually connected to the mainland of Asia by a narrow strip of land.
In the middle of South Korea, there are a bunch of mountains called the Taebaek Mountains. They run from north to south and divide the country into two regions: the western region and the eastern region. The western region is flatter and has many cities and towns, while the eastern region is more rugged and has a lot of natural beauty like national parks and beaches.
The biggest city in South Korea is Seoul, which is located in the northwest part of the country. It's the capital city and home to many important government offices, businesses, and universities.
South Korea is also known for its many islands, which are scattered along the southern coast. Some of these islands are populated, while others are completely uninhabited.
Overall, South Korea is a small country with a lot of different landscapes and environments. It's a beautiful place with mountains, beaches, cities, and everything in between.
