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 else can I help you with?
What types of rocks are near active volcanoes and why?
When lava cools, it forms what is known as an extrusive igneous rock. Volcanoes are also associated with alteration from heat and fluids. Therefore you would expect to find extrusive rocks as well as altered rocks.
What kind of rocks would you expect to find near a volcano thathas erupted?
Extrusive, Igneous rocks possibly lavas or ignimbrites.
What type of rocks would you expect to find around a volcano crater?
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Why would you expect the crystals in an intrusive rock to be larger than the crystals in the extrusive rock?
Because as an intrusive rock cools underground, it will normally cool more slowly than an extrusive (surface) rock. The slow cooling allows more time for the crystals to grow.

extrusive ingeneous rocks

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.

What is mean by implied condition as to quality or fitness?
Implied conditions are standards that we expect even though it is not covered in the law (sometimes). For quality, we expect it to at least be in good condition. For fitness, we expect it to do the job it is meant to do e.g. we buy an ipod, we expect it to let us listen to music.

What price can I expect to get for a used soda machine?
Depending on size and condition, you can realistically expect around $500 for a used soda machine.
What is the cost of a Jaguar XJ220?
Depending on the condition and availability, expect to pay about £150,000
How much is a 1902 E pluribus unum dollar coin worth?
You are holding a Morgan Dollar. You could expect to get around $17 for this coin in typical circulated condition. Of course though, the better the condition, the more you can expect to get for it.
How much should one expect to pay for a 1970 Pontiac GTO in good condition?
There are plenty of different ideas on how much on should expect to pay for a 1970 Pontiac GTO in good condition. However, it is around 50,000 dollars at the average.
