Coarse-grained rocks typically weather faster than fine-grained rocks because their larger grain sizes allow for more exposure to environmental factors such as water, air, and temperature changes. The increased surface area of coarse-grained rocks facilitates the chemical and physical processes of weathering. In contrast, fine-grained rocks tend to be more compact and less permeable, slowing down the weathering process.
What else can I help you with?
Which would weather faster between coarse-grained and fine-grained?
Fine-grained materials weather faster than coarse-grained materials. This is because fine-grained materials have a larger surface area relative to their volume, allowing for more exposure to weathering agents like water and air. Additionally, the smaller particles can be more easily broken down by physical and chemical processes. Thus, fine-grained rocks generally undergo weathering at a quicker rate than their coarse-grained counterparts.
Would you expect a course grained extrusive rock like dacite to form?
Dacite is typically an intermediate volcanic rock that forms from the rapid cooling of lava at or near the Earth's surface, resulting in a fine-grained texture. However, if it were to form as a coarse-grained rock, it would likely require a longer cooling period, suggesting a more intrusive environment, such as a shallow magma chamber. In its typical extrusive form, dacite does not exhibit coarse grain; thus, it is unlikely for coarse-grained dacite to form under standard conditions of rapid lava cooling.
What rock is course grained?
Coarse-grained rocks are typically igneous or metamorphic rocks that have crystals large enough to be seen with the naked eye. An example of a coarse-grained igneous rock is granite, which is composed of large crystals of minerals like quartz, feldspar, and mica. In metamorphic rocks, an example would be gneiss, which exhibits a banded texture with visible mineral grains. The coarse grain size indicates that these rocks formed slowly, allowing crystals to grow larger.
Why does limestone erode quickly?
It depends on: - the strength of the acid - concentration of the acid - temperature of the solution - stirring of the solution - granulation of the lime
A sedimentray rock composed of what would weather at a faster rate?
Chalk would weather fastest, followed by limestone.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.

Is limestone coarse grained or fine grained?
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
A coarse-grained rock and a fine-grained rock probably had different what?
Methods of formation. If crystalline (igneous or metamorphic) they would most likely have had differing rates of cooling. If sedimentary, they would most likely have had differing depositional environments (higher energy for larger grain sizes).
When all the grains in a rock are easy to see the rock is described as what?
Visible crystals or grains would be referred to as a coarse grained texture.
How long it will take coarse grained rock to become fine grained rock?
The period of time involved in the rock cycle which would involve the transformation of a coarse grained rock into weathered, eroded, transported, deposited, and cemented fine-grained sedimentary particles would vary greatly. Suffice it to say the entire process would take many thousands-to-millions of years.
