Scoria is a type of volcanic rock that forms from the rapid cooling of lava rich in gas. Here's a detailed explanation:

Formation: Scoria is typically formed during volcanic eruptions when dissolved gases in the magma come out of solution as the pressure decreases, creating bubbles in the lava. When this gas-charged lava is ejected and cools quickly, it solidifies with these bubbles trapped inside, resulting in a porous texture.
Characteristics:
Texture: Scoria has a vesicular texture, meaning it is full of small cavities or vesicles, which are the remnants of gas bubbles. These vesicles can give scoria a lightweight, pumice-like appearance, though scoria is generally denser than pumice.
Color: It is usually dark in color, ranging from black to dark brown or reddish-brown, due to its high iron and magnesium content.
Composition: Scoria is primarily basaltic or andesitic in composition, containing minerals like plagioclase, pyroxene, and olivine.
Uses: Scoria is used in construction for lightweight concrete,
