In the USA there are lots of farmlands and grasslands,***, mountains, caves and sun. The Mississippi River flows southwards. It rises in northern Minnesota and flows to the south - to the Mississippi River Delta at the Gulf of Mexico . It is an important waterway. Also in the city you can see skyscrapers.
