What happens to the density of water when a large amount of salt is dissolved in it?

In the ocean, 'deep water currents' are often driven by differences in water density. Which combination of factors would create the densest, most likely to sink water?

What happens to the density of a body of water if the sun warms the top layer while the deep water remains very cold?

Which specific process describes how water is released into the atmosphere by the leaves of plants?

When solid ice or snow turns directly into water vapor without melting into liquid water first, it is known as:

A student builds a model of a mountain using a pile of soil and pours water over the top to see how it flows down into a small pool at the bottom. Which part of the water cycle is primarily being modeled by the water flowing down the soil?

In a physical model of the water cycle, a student uses a sponge to represent a cloud. When the student squeezes the sponge and water falls out, which part of the water cycle is being demonstrated?

In a model using a sealed plastic bag with some water inside, a student hangs the bag in a sunny window. If the student adds a small green plant inside the bag, they are adding a way to model which specific process?

In a water cycle model involving a glass jar and a metal tray of ice on top, why do 'rain' droplets eventually fall from the bottom of the tray?

In a laboratory model, a student pours water onto a layer of dry sand and pebbles in a clear container. They observe the water sinking through the spaces between the grains until it reaches the bottom. Which part of the water cycle does this movement represent?
