Which of the rocks will weather most rapidly?
Sedimentary rocks usually weather more easily. For example, limestone dissolves in weak acids like rainwater. Different types of sedimentary rocks can weather differently.
Which of the rocks will weather most rapidly Why?
Mafic silicates like olivine and pyroxene tend to weather much faster than felsic minerals like quartz and feldspar. Different minerals show different degrees of solubility in water in that some minerals dissolve much more readily than others.
What type of weathering is most common in limestone?
chemical weathering Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve.
Which type of climate will weather limestone fastest?
Some types of rocks weather more rapidly in humid climates, while dry climates make other rocks more susceptible to attack. Limestone weathers rapidly in areas with wet climates, where rainwater mixed with carbon dioxide in soil or creates a weak acid that dissolves the limestone to form crevices and valleys.
Does limestone weather easily?
Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. This is because calcium carbonate, which is one of the minerals found in limestone, readily reacts with rainwater. Rainwater can get acidic because of the carbonic acid that it contains.
Which of the following conditions sedimentary rocks weather faster?
Climate- High amounts of water and higher temperatures generally cause chemical reactions to run faster. Thus warm humid climates generally have more highly weathered rock, and rates of weathering are higher than in cold dry climates.

What does limestone weather into?
In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis – the breakdown of rock by acidic water to produce clay and soluble salts.
What weather is limestone?
Limestone is chemically weathered by a process of carbonation. As rainwater absorbs carbon dioxide as it passes through the atmosphere it becomes a weak carbonic acid. The water and carbon dioxide combine to form a weak carbonic acid.
Why is limestone so easily weathered?
Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
What type of weathering is limestone resistant to?
The Influence of Climate Many rocks are resistant to one kind of weathering and weak against the other. Limestone, for instance, is notably prone to chemical weathering given the solubility of its carbonate rock; in humid limestone provinces, caves and caverns – examples of karst landforms – abound.
What conditions produce the fastest weathering?
Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates. Without temperature changes, ice wedging cannot occur. In very cold, dry areas, there is little weathering.
In which climate would the chemical weathering of limestone occur most rapidly a cold and dry b cold and humid C warm and dry d warm and humid?
Chemical weathering occurs more rapidly in regions where temperatures are higher and where the amount of precipitation is evidently higher. Moisture can only speed up the rate of chemical weathering.
Which of the following rocks will most rapidly weather when exposed to acid rain quartzite B granite c basalt D marble?
The answer is d) limestone. Limestones is formed when lime mud, principally composed of Calcium Carbonate (CaCO3 C a C O 3 ) precipitates from sea or lake water.
What minerals are found in limestone?
The minerals calcite and dolomite are the main ingredients of limestone. Both are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O).
What is limestone made of?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
What is limestone composed of?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
In which of the following weather conditions will chemical weathering be most rapid?
Where does it occur? These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.
Which rock weathers most rapidly when exposed to acid rain a quartzite B granite c basalt D limestone?
Answer and Explanation: The answer is d) limestone. Limestones is formed when lime mud, principally composed of Calcium Carbonate (CaCO3 C a C O 3 ) precipitates from sea or lake water.
What type of sedimentary rock is limestone?
Limestone;Limestone is a non-clastic sedimentary rock which is produced from the mineral calcite and from sediment. It is very abundant, can be easily dissolved by acids, and is used in architecture. Limestone is a sedimentary rock that is mainly composed of calicite which is found in the shells of sea animals.
What rock is made from limestone?
Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago.
What minerals does limestone contain?
The minerals calcite and dolomite are the main ingredients of limestone. Both are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O).
In which climate would chemical weathering of limestone occur most rapidly 1 cold and dry 2 cold and humid 3 warm and dry 4 warm and humid?
Chemical weathering occurs more rapidly in regions where temperatures are higher and where the amount of precipitation is evidently higher. Moisture can only speed up the rate of chemical weathering.
What mineral does limestone contain?
calcium carbonate Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
Does limestone contain calcium?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
In which of the following climates will chemical weathering be most rapid a hot and dry b cold and dry C hot and humid D cold and humid?
Chemical weathering, also known as decomposition or decay, is the breakdown of rock by chemical mechanisms. These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.
What is limestone formed from?
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.
What is limestone made up of?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
In which of the following climate region will chemical weathering be most rapid?
Rocks in humid regions are exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. Hence, the chemical weathering process is more dominant than the mechanical process in humid regions. Hence, Option 1 is correct.
How is limestone sedimentary rock formed?
Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms.
