What type of chemical weathering is associated with limestone?
Normal rain (slowly) and acid rain (rapidly) both weather limestone.
How does acid rain weather rocks?
Acid rain is corrosive and reacts with the minerals in the rocks, sometimes dissolving them and sometimes making them change into a gas. This weakens the rocks which then fall apart and get washed away.
What is chemical wearthering?
it is chemical and and u can weather it
How might Cobalt Chloride be used to predict weather changes?
It is blue and when hit by water turns pink therefore it can be used as an indicatior for water or condensation such as rain or steam in weather.
The sun's energy drives which of the following processes?
Weather and ocean circulation.
Why do sandstones cemented with calcite usually weather much more rapidly than sandstone cemented by silica?
The cementing mineral calcite is not resistant to chemical dissolution by naturally acidic rainwater as is the cementing silicate mineral.
Are limestone rocks least susceptible to weathering?
No! Limestone is composed of significant amounts of calcite (calcium carbonate - CaCO3) which is soluble and so is relatively easy to weather.
Why is limestone changed into marble?
Limestone is softer than marble because of how they are formed inside. Marble consists of tightly interlocked crystals, which makes it stronger than limestone. Limestone consists of small fossil fragments and smaller crystals, which makes it weaker than marble.
Why does calcite weather faster?
cause its green
How long does it take for rock to turn into marble?
Marble is formed through the metamorphism of limestone. The fact that marble gleams white and reflects object, informs us that it has gone through the metamorphic stage, withstanding heat, water, wind, ice, etc. Through this change, limestone has become a smooth, glossy, fire resistant, and weather resistant marble.
Why does limestone often form cliffs in dry climates but rarely form cliffs in wet climates?
This is because in the wet climates the limestone will break apart due to the rain. And in dry climates it does nothing to the limestone. Therefore, this is why limestone can form cliffs in dry climates than wet climates.
Which weathers faster granite or marble?
Marble will weather more quickly. The mineral calcite, of which marble is composed is softer and less resistant to abrasion than granite. It is also more susceptible to chemical weathering via natural and man-caused acidic rainfall due to its chemical composition. Granite--not so susceptible.
What types of rock does carbonic acid weather easily?
calcite
Can soda weather limestone?
yes
Would high pH water weather limestone?
From what I know, limestone is alkali, and high pH water would not weather alkali things. For the case of limestone, it might even make the limestone bigger (think so).
What does calcite weather to form during dissolution?
carbonic acid
What rock type is easiest to weather?
Limestone
