• A basin is a hollow ordepression in Earth's surface with no outlet for water. This
means that any water that originates in orflows into a basin does not escapeit. A
basin can be approximately circular,resembling a bowl, orit can be oval-shaped. It
can be a small structure, measuring only a few miles in diameter. Often, it is much
larger. Abasin is usually surrounded mostly by higher land. Depending on where it
is located, a basin may sometimes include desert areas, which arearid ordry
regions receiving less than 10 inches (25 centimeters) of rain per year.
