False
False. Ice is *less* dense than water. If it weren't, water would freeze from the bottom up, killing all the fish etc during the winter. Water contracts as it is gets colder, but at the moment it freezes, crystals form. These are hard bonds that push the molecules farther apart, thinning the density of the water, and making ice remarkably strong. A few inches of ice can support the weight of a person.
false
true
Yes; at divergent/constructive boundaries, plates move apart and new oceanic lithosphere forms.
False
It is false.
False. An increase in frequency means a decrease in the wavelength and a decrease in frequency goes with an increase in the wavelength.
true!
The answer is FALSE.
false
False. The magnetic force of attraction or repulsion between the magnetic poles is inversely proportional to the square of the distance between the poles. So farther apart two magnets the force between them becomes weaker.
False.

No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
False
