Diffusion is the process where water molecules move from a negative water potential to a more negative water potential through a semi permeable membrane.

Using the elimination method to remove the variable x, we need both equations to have the same values of x. To do this we find the lowest common multiple of the x values: the lowest common multiple of 3 a...

An object in free fall is only subject to the gravitational force from the earth. The magnitude of this force is mg, where m is the mass of the object. Newton's second law states that the force on an obje...

Mechanical weathering.Very high temperatures during the day determine the expansion of rocks. Contraction occurs during the night when temperatures are very low, sometimes bellow freezing point. Therefore...

The oceanic crust is generally younger than the continental crust as it is less than 200 million years old and can also be renewed or destroyed at plate boundaries. For example, the oceanic crust which fo...
