Phosphorus: Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate (A phosphate is a salt of phosphorus acid) rocks to break down and released by lichens can cause chemical weathering. In physical weathering, processes such as wind, rain, and freezing release particles of rock and phosphate into soil. However, most phosphate in run-off settles on lake and ocean bottoms and will not enter the biotic community unless the sediment is disturbed.Nitrogen: Excess nitrate and ammonium that are not taken up by plants mix with rainwater and are washed from the soil into the ground water and streams. This unused nitrogen may settle to ocean, lake, or river bottoms in sediments. Eventually, these sediments will form rock and the nitrogen will not be available. Only after centuries of weathering will the nitrogen be released into the water.
In general, ionization INCREASES as you move to the right and up in the periodic table, making P (Phosphorus) higher than Ca (Calcium).
it moves by swimming around in circles
They move slower because in a solid the molecule move faster and in a gas they move slower, therefore, they will move slower. :)
Those that are motile and have flagella do move on their own, while those that are sessile do not move on their own.

Before the railroads were built, farmers had to haul their crops on wagons. This was one reason the farmers who wanted to export part of their crops settled near rivers or near the Atlantic ocean.
they dont move!
Ocean currents.
because it is easyer to move in the ocean
In order to have healthy crops the Egyptians used irrigation techniques to water their crops. Irrigation is the artificial application of water to crops.

waters of the ocean that move in giant streams are called currents.
As you move away from the ocean it gets less and less windy
