A. The moon is thought to have a mantle and crust somewhat like the Earth's. There are lighter minerals such as feldspar and pyroxene and olivine on the surface. Another layer of the moon's surface is made up of basalt, formed by giant lava flows.

A. Women's tennis and golf are big-money professional sports. In Europe, they have professional women's basketball teams. And professional volleyball players are making a living from the game on the beaches of California. The movie "A League of Their Own" told the story of an attempt to start a women's baseball league. It seems as if it is only a matter of time before women will be raking in big-money contracts for team sports.
