Rainwater is usually slightly acidic because of the carbon dioxide dissolved in it. Sometimes, it can be strongly acidic, if pollutants like sulphur dioxide and nitrogen dioxide are dissolved in it.
Both weakly and strongly acidic rainwater react with some rocks, but only ones that are alkaline. Chalk is almost pure calcium carbonate and reacts fairly quickly with rainwater. Other rocks that contain calcium carbonate include limestone and marble and these react a little more slowly. But some rocks, like sandstone, are actually acidic and don't react with rainwater (though they are still physically weathered by rain). Granite also doesn't react with rainwater and it physically weathers much more slowly.
What else can I help you with?
If three rocks have the same mass will the weathering rate be the same?
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.
How does acid rain affect rocks?
Rainwater contains carbonic acid, and chemically reacts with rocks, particularly carbonate ones, dissolving them slowly.As sulphur and other gases (most commonly found as byproducts of industrial activities) diffuse into clouds, the overall acidity of the rainwater will increase. In small amount this is not a real problem, but when the amounts begin to increase you can get problems such as acid rain. As rainwater is naturally acidic the effects of pure rainwater on rocks will be the same as those with acid rain (although the rate of acid decay of the rock will be higher with acid rain). The effects of the acid rain are most noticeable on limestone (as it is very susceptible to acid erosion due to its high carbon content). The acid will corrode the surface of the rock, allowing to be more easily dissolved into the water and carried away. Over time this can cause serious problems to the overall structure of the rock. If acid rain affects buildings then the outer walls will often be checked to ensure that they will still be able to help support the building.
Does rainwater absorb at the same rate in different kind of soil?
No, rainwater absorption rates can vary in different types of soil due to factors like soil composition, compaction, and porosity. Sandy soil allows water to absorb quickly due to its large particles and high permeability, while clay soil has smaller particles and lower permeability, leading to slower absorption rates.
Is rainwater absorbed at the same rate in different lands of soil?
Rainwater absorption rate can vary depending on the type of soil. Sandy soils tend to absorb water more quickly due to their larger particles and greater pore spaces, while clay soils absorb water more slowly because of their smaller particles and compacted structure. Loamy soils, which are a mixture of sand, silt, and clay, have a moderate absorption rate.
Are rocks and stones the same thing?
No, rocks and stones are not the same thing. Rocks are made up of one or more minerals, while stones are small pieces of rock.
If three rocks have the same mass will the weathering rate be the same?
Not necessarily. Weathering rates would depend on the rock type, mineral composition, and density. These factors will determine a rock's resistance to acidic rainwater, freeze/thaw cycles, and abrasion.
Find out the names of two rocks that can be chemically weathered by natral rainwater?
I had the exact same question for one of my exams... I am fairly sure that the answer is: Granite and Limestone are two rocks that can be chemically weathered by natural rainwater. Hope I helped ! Alexx
Does rainwater absorb at the same rate in different types of soil?
Different plants have different nutrients , so no
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
Would an alluminum can react the same way as powdered alluminum?
No. Freshly powdered Al react at fast rate than freshly cut Al.

Is rainwater the same as distilled water?
No, rainwater is not the same as distilled water. Rainwater is collected from the atmosphere and may contain impurities, while distilled water is created through a process of boiling and condensation to remove impurities.
Where rocks on opposite side of a fault move in opposite directions or in the same directions at different rate?

Will rainwater and sea water boil at the same temperature?
No, rainwater and seawater will not boil at the same temperature. Seawater has a higher boiling point than rainwater due to the presence of dissolved salts and minerals, which raise the boiling point of the water.
What is the temperature of standing water?
Rainwater is usually the same temperature as the surrounding atmosphere.
