Drainage basin—area drained by river and its tributaries. D. Ground Water 1. Ground water—water held in the pores of rock. 2. Water table—level at which the rock is saturated.
  5. 5. E.Landforms 1. Landforms are naturally formed features on Earth’s surface F.Oceanic Landforms 1. Continental shelf—sea floor from continent’s edge to deep ocean. 2. Sea floor has ridges, valleys, canyons, plains, mountain ranges. 3. Islands are formed by volcanoes, sand, or coral deposits.
