| trenches | valleys on the floor of the ocean |
| Unit 1 strait | a narrow body of water between two pieces of land--'water connects water'--like between Spain and Africa |
| Unit 1 channel | the same as a strait but wider |
| Unit 1 delta | soil/silt washes down rivers and deposits (dumps out) into an ocean, sea, or gulf -the silt starts building up and creates little island-like areas at the mouth of the river (where the river flows into the gulf, etc) |
| water vapor | water that turns into gas-evaporated water coming from the water on the surface of the earth-the gas cools and condenses forming clouds |
| water cycle | when the water goes from the oceans to the air to the ground and finally back to the oceans |
