Question | Answer |
(P.O.W.)Why is Ice is less dense than water | As water freezes the molecules spread out in a six-sided pattern. |
(P.O.W.)Why can some insects walk on the surface of water. | water molecules at the surface of water have enough cohesion |
(P.O.W.)why does sodium dissolve when put in water | attractions cause the sodium and chloride ions to break apart in water, or dissolve. |
(P.O.W.)What is polarity | Polarity is a condition in which opposite ends of a molecule have slightly opposite charges, but the overall charge of the molecule is neutral |
(P.O.W.)what is a water atom made out of and the charges of each one | 2 Hydrogen charge positive,1 Oxygen charge negative |
(P.O.W.)Why is water called the universal solvent | because so many substances can dissolve in it |
(P.O.W.)What makes water a unique compound | B/c water is the only substance that exists in nature as a solid, a liquid, and a gas |
(P.O.W.)The density of freshwater is greatest at what temperature | 4 degrees Celsius |
(O.C)What is a effect of a Coriolis effect | The Coriolis effect causes fluids to move clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere |
(O.C)What is upwelling | The vertical movement of water toward the ocean’s surface |
(O.C)What is another type of vertical current | A density current |
(O.C)What is a density current | Density currents move water downward,they carry water from the surface to deeper parts of the ocean |
(O.C)True or false cold water is denser than warm water | True |
(O.C)What happens when a surface current moves toward a polar area | the water cools |
(O.C)When seawater freezes what happens to the salt | The salt is left behind in the surrounding water |
(O.C)Density currents are important components of what | Ocean circulation |
(O.Comp.)2 sources of water for earths oceans | Water from volcanoes,melted ice from comets and asteroids |
(O.Comp.)What is salinty | The measure of the mass of dissolved solids in a mass of water |
(O.Comp.)Fresh water mixed with seawater is called | Brackish water |
(O.Comp.)Where dose salinity(salt) in the ocean come from | Rain washes over rocks dissolves minarals and rivers and streams carry it to the oceans |
(O.Comp.)4 criteria that scientist use to classify ocean zones | amount of sun light,salinity,density,temperture |
(O.Comp.)What is the deepest part of the ocean | Ocean trench |
(O.Comp.)How many ocean zones are there and what are they | surface zone, middle zone, deep zone |
(O.Comp.)What are some natural resources from the ocean floor | oil,natural gas and methane |
