Under which condition below would you expect a glassy extrusive rock like obsidian to form?
Obsidian is formed as extruded lava with a high silicon content that cools quickly. So the environment would be a volcano.
If Smaller crystals in igneous rock form when?
Smaller crystals form in igneous rocks if they are extrusive, meaning they formed at or near the Earth's surface. Because of the quick cooling of the magma/lava, there is no time for the crystal structure to expand, leaving it smaller than if it was an intrusive rock (forming inside the Earth, below the surface).
Under what condition would you expect a coarse-grained intrusive rock like diorite to form?
lava slowly flowing out of a Quick cooling on Earth's surface. apex
What causes large crystals in intrusive igneous rocks?
Intrusive igneous rock is formed underground by the slow cooling of magma. With the insulating and heat retention effects of an underground environment, ions are free to move about the fluid magma and join onto growing mineral crystals. In a quick cooling environment, crystallization occurs rapidly, with little time for crystal growth.
Why do most mineral samples not visibly show their crystal form?
because of quick cooling igneous rocks .
Are amorphous solids formed as a result of quick cooling?
Yes. Quick cooling doesn't allow sufficient time for the crystal structure to organize.
What are quick moving winds that flow high above earths surface?
seasons

Obsidian is formed as extruded lava with a high silicon content that cools quickly. So the environment would be a volcano.
What is extremely rapid cooling of lava in which no crystals form?
Extremely rapid cooling of lava results in the formation of volcanic glass, where no crystals have time to form due to the quick cooling process. This volcanic glass is also known as obsidian and has a smooth, shiny appearance.
What does quick cooling of ejected lava result in?
Quick cooling lava will result in extrusive igneous rock, a type of rock classification based on its small crystals being formed from lack of time for growth during solidification.
What kind of ingeous rock would it be if magma crystallizes before it reaches earths surface?
This depends on the rapidity of the cooling. If the cooling is very slow, then one of the granites will result, identifiable by the type and presence of macro crystals - each a different mineral.If the cooling were fairly quick, then basalt polygonswill be formed ( as seen in the Giants Causeway), and these can approach a metre in dimension. These are of course, pseudo-crystals, not crystals in the mineral sense. They are the common substrate of all the rock as it spreads out from mid-ocean ridges. They are also not uncommon in volcanic outcrops.
What does a fine-grass igneous rock forms?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
Why does obsidian have a glassy texture?
Obsidian has a glassy texture because it forms from rapidly cooling lava without much time for crystal growth. This quick cooling process prevents the formation of crystals, resulting in a smooth and reflective surface similar to glass.
A fine grained igneous rock forms?
quick cooling

What is in Cooling Fins on A Radiator?
Cooling fins on a radiator are thin, metal pieces that are attached to the radiator tubes. They help to dissipate heat from the hot coolant as air passes over them, increasing the surface area for more efficient heat transfer. Cooling fins play a crucial role in the cooling process by assisting in the quick removal of heat from the coolant before it is recirculated back into the engine.
