It doesn't, necessarily. If it's made of a kind of mineral that is grey, then it will.
Lava isn't inherently red... it's red because it's red hot. When it cools, the resulting rock will be whatever its normal color is.
A volcanic eruption can lead to a lot of death to everything and once hit it is a very sudden death and the lava with eventually turn to rock and you will be a statue after a while because you are preserved under the hard lava...
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
The eruption of the boiling hot lava sent the small town into panic.
No. A lava flow usually indicates an eruption that is not explosive.
A river of lava is called a lava flow. It is a mass of flowing molten rock that moves downhill from a volcano during an eruption.
Lava is not weather, it is the result of a volcano eruption. The eruption itself can cause weather issues such as falling ash and clouds, but lava is not considered "weather".
quiet eruption flows easeir cause it has a low viscosity and lava flows easier but explosive eruption has a high viscosity and lava flows slower
magma turns into lava.
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
