Which do you think will weather at a faster rate sandstone or grantie?
sandstone will weather faster because it is softer than granite.
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.
Does sandstone weather faster than basalt?
yes
What does calcite weather to form during dissolution?
carbonic acid
In what climate would a limestone monument weather most quickly?
The type of climate that a limestone will weather more quickly i think will be a hot and dry climate.
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.
How is sandstone affected by the weather?
Because sandstone is a sedimentary rock and is made of calcite, the rain weathers most rapidly.
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.
What substance in rainwater makes it so limestone weather easier than sandstone?
Carbon dioxide dissolved in rain water forms a weak acid which slowly weathers limestone, a carbonate which reacts with acids.
Which do you think will weather at a faster rate sandstone or grantie?
sandstone will weather faster because it is softer than granite.
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 have sandstone and limestone been used as building materials for thousands of years?
Sandstone and limestone have been used as building materials for thousands of years because they stand up well to the weather. They are natural sedimentary rocks that can last for thousands of years especially in dry climates like Egypt.
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.
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.
How is Granite different from Sandstone?
Granite is an igneous rock formed from the cooling of molten magma deep within the Earth's crust, characterized by its interlocking crystals of minerals like feldspar, quartz, and mica. Sandstone, on the other hand, is a sedimentary rock composed of sand-sized mineral particles and rock fragments, usually cemented together by minerals like quartz or calcite. Granite is more durable and resistant to weathering compared to sandstone.
