Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate rocks to break down and release phosphate into soil. Acid precipitation and the chemicals released by lichen can cause the chemical weathering. In physical weathering, processes like wind, rain, and freezing releases particles of rock and phosphate into the soil.

When does a rock have lower rate of weathering?
a rock would have a lower rate of weathering when it has more surface area exposed to weathering.
While physical weathering will break a rock into chunks what turns the rock into soil?
chemical weathering
What is phosphorus rock?
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. See attached link for more information.
How weathering change rocks?
how does weathering change rock
Explanations of the three types of weathering?
chemical weathering is when a chemical reacts with a rock to brake down a rock.
How does weathering releases phosphate from rock?
Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate rocks to break down and release phosphate into soil. Acid precipitation and the chemicals released by lichen can cause the chemical weathering. In physical weathering, processes like wind, rain, and freezing releases particles of rock and phosphate into the soil.
How do phosphorous and nitrogen move from land into the ocean?
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.
Is phosphate rock an igneous rock?
no, it is actually a chemical!answ2. Phosphate rock is a sedimentary rock.
What happens to a rock when they are uplifted to the surface of the earth?
Pressure on them is released, which can cause pressure-release mechanical weathering. Exposure of an uplifted rock to the surface will fully expose the rock to the effects of mechanical and chemical weathering--basically a rock rot.
How does release of pressure affect mechanical weathering?
There are two main types of weathering: mechanical (also called 'physical') and chemical. Pressure release is a form of mechanical weathering. Pressure release usually occurs when rock that has been deeply buried, rises toward the surface due to the erosion of the mass of rock above it. Pressure release causes fractures and exfoliation in the depressurizing rock body. These fractures in the rock make it more susceptible to, and accelerate, other modes of mechanical weathering attack, such as freeze/thaw hydraulics and plant root growth.
How does phosphorus enter an ecosystem?
Phosphate enters aquatic ecosystems as a result of erosion, leaching, run-off.
What is the difference between rock phosphate and calcium phosphate?
One is a powder and the other is a rock
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
While physical weathering will break a rock into chunks what turns the rock into soil?
chemical weathering
When does a rock have lower rate of weathering?
a rock would have a lower rate of weathering when it has more surface area exposed to weathering.
What is phosphorus rock?
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. See attached link for more information.
Rock formed from the fusion of weathering?
Weathering may change the rock into many shapes.
