Magma flows for a long period of time but named lava when out of the ground. It depends how fast the lava is travels, but you can usually run from it:)
Until the magma chamber feeding it runs out of magma.
The time it takes for magma to complete a circular convection flow can vary depending on factors such as temperature, viscosity, and the size of the magma chamber. In general, this process can take anywhere from days to centuries.
The cooling rate of magma plays a significant role in determining the size of crystals.
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller
A coarse-grained texture typically represents a single long period of cooling and crystallization. This texture forms when the magma has had enough time to cool slowly and crystals have had time to grow to a visible size.
Until the objects touching have equal temperatures.
The lava must cool to become a rock, and the cooling time can vary greatly because of many variables in the process. These variables include the temperature of the air around the lava and the contents of the the lava. The cooling process usually takes a very long time.
Intrusive rocks form over tens of thousands to millions of years as molten rock, or magma, slowly cools and solidifies beneath the Earth's surface. The cooling process is influenced by various factors, including depth of burial, rate of cooling, and composition of the magma.
because
Yes, as long as the air has a place to flow to. If you use evaporative (swamp) cooling you are creating a positive pressure inside a building, if that pressure has an outlet like windows slightly cracked, the cooler air moves farea of entry, to the area of exit.
Pipe?
It doesn't necessarily matter what the minerals are, as long as they form from cooling magma or lava. Igneous rocks are formed by the solidification of cooled magma (molten rock). They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
