Adhesion Responsible for water molecules sticking to other surfaces (the attraction of molecules that are not alike.)
Density mass per unit volume of a material
What are the 3 states of water? Solid, liquid, gas
What is evaporation? The process by which water molecules in liquid water escape into the air as water vapor.
What is relative humidity? The percentage of water vapor actually in the air compared to the amount the air can hold at a particular temperature.
What is condensation? The process by which molecules of water vapor in the air become liquid water.
What is fog? Suspension of water droplets or ice crystals close to or at Earth's surface.
What is an iceberg? a large floating mass of ice detached from a glacier or ice sheet and carried out to sea.

What are the four criteria's scientists use when classifying ocean zones. 1. Amount of Sunlight 2. Temperature 3. Salinity 4. Density
Why is river water sometimes salty near the ocean? Water pours into the ocean and tides rise and fall so the water mixes.
Ocean water is _____ water? Salt
What does sea level mean? That the land is the same height or level as the sea.
The amount of salt in the ocean has/ has not changed? has not
Why are rivers and lakes not salty? The salt in there rivers/lakes flow toward the ocean.
What does the heat from the sun do to the water in the ocean leaving only salt behind? It evaporates the water leaving only salt behind.
Warm air holds more or less heat than warm air? less air
What is the most powerful ocean current (close to the Gulf Stream) , which is in which ocean? Atlantic Ocean
