Earth Science Density

 What is the formula for density? D= M/V Density is a property of _______. Matter. Why is it important that ice floats? Higher water levels = land goes under water, destroying habitatsDestroy marine life = Ice is an insulator that keeps the water at a good temperature. It would sink and stop insulating the surfaceIce would have trouble melting in the summer = it gets accumulated making all water ice If an object has a density of 1.7 g/ml, will it float? If so, how much of it is in the water? It will not float If an object has a density of 0.4 g/ml, will it float? If so, how much of it is in the water? Yes, it will float. 40% of the object will be in the water If an object has a density of 1.0 g/ml, will it float? If so, how much of it is in the water? It is neutrally buoyant, meaning it is all in the water, but it doesn't sink. If an object has a density of 2.39 g/ml, will it float? If so, how much of it is in the water? It will not float If an object has a density of .82147 g/ml, will it float? If so, how much of it is in the water? It will float. 82.147% of the object will be in the water The density of an object will ______ __ _____, even if it is _________ Remain the same, bigger/smaller The only way to change the density of an object is to _____ or _____ Apply compression, change the temperature Use a ______ to find the volume of an irregular shaped object that is too big for a graduated cylinder. Overflow can If you were to explain what density is, how do you describe it? Density is the amount of matter packed into a space. A more dense object is tightly packed together with matter (like lead or gold). A less dense object is more spread out with matter (like styrofoam) When is the density of matter at it's highest point? 38 degrees F, 4 degrees C Cold air will _____ because it is _______ than warm air sink, denser Warm air will _____ because it is _______ than cold air Rise, less dense Convection The rising and falling motion of air. Extreme _____ leads to hurricanes, tornado's, and other natural disasters. Convection AuthorMoonRacer ID35222 Card SetEarth Science Density DescriptionCards on Density.
