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.
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.
What condition would you expect a coarse-grained extrusive rock like dacite to form?
Coarse-grained extrusive rocks like dacite typically form under conditions of relatively slow cooling, which allows larger crystals to develop. This often occurs in volcanic environments where magma is expelled from a volcano and cools quickly upon reaching the surface, yet retains some degree of insulation, such as being trapped in a thick lava flow. The presence of gas bubbles and the viscosity of the lava can also influence crystal growth, leading to a textured appearance. However, true coarse-grained textures are more characteristic of intrusive rocks; dacite is generally fine-grained due to rapid cooling, suggesting a need for reconsideration of the classification.
What type of crystal grain forms when molten rocks cool slowly?
Quartz
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.

Visible crystals or grains would be referred to as a coarse grained texture.
What condition under below would you expect a coarse-grained intrusive rock like diorite to form?
Slow cooling in the upper mantle

Under which condition below would you expect a coarse grained extrusive rock?
You would expect a coarse-grained extrusive rock when the magma cools and solidifies slowly underground, allowing larger crystals to form due to extended cooling time. This can happen in magma chambers or in deep-seated volcanic environments where the magma has more time to cool and crystallize before reaching the surface.

Chalk would weather fastest, followed by limestone.
