The color of igneous rocks is tied to their composition. Rocks (minerals) that have a high concentration of Fe, Mg and Ca, tend to be darker colored than those that are rich in Al, Si, and K. So, the volcanic rocks like rhyolite are light in color due to their composition. However, there are many volcanic rocks, like andesites, that are a bit darker, and those form from explosive volcanoes like the Cascade volcanoes of western North America.
Dark because the volcano explosian is very dark color of lava thats also formed with heat .
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Extrusive, Igneous rocks possibly lavas or ignimbrites.
extrusive ingeneous rocks
it demonstrates ash, cinders and bombs
extrusive igneous rock
The type of rock that you would expect to form as the result of an explosive eruption is Pumice.
What you would expect after an explosive eruption is darkened skies. You should also expect warmer temperatures.
You would expect to find lava solidifying into basalt on the flanks of a volcano, most likely a shield volcano.
A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface. So expect explosions and a lot of noise.
you would find igneous rocks with small crystals at the bottom of the volcano, this is because when the rocks crack. It brakes apart into igneous rocks
The volcano drains the lava by erupting. There is no internal drainage network.
Lava slowly flowing out of a fracture in the Earth's surface :)
Quick cooling on Earth's surface
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.
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.
Yes because there is a volcano there that is still active?
