The most common blue/bluish minerals of this type include azurite, chalcanthite, chrysocolla, linarite, opal, smithsonite, turquoise, and vivianite. Most people will not find these in the field, but any decent rock shop will have them all.
Green and greenish rocks get their color from minerals that contain iron or chromium and sometimes manganese. By studying a material’s grain, color, and texture, you can easily identify the presence of one of the minerals below.
Hot volcano lava would instantly burn away your taste buds so the taste would not be discernible.

A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. By this definition, a sufficient amount ice can usually be considered to be a rock.
A café in the Westfjords offers edible pieces of lava. In addition to regular menu items like café latte, cakes and sandwiches you can order edible lava at Bræðraborg Café in the town of Ísafjörður in the Westfjords.
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.
The igneous rock layer is younger than the sedimentary layers under it and older than the sedimentary layers that form on top of it. Why is igneous rock always younger than any rock it cuts through? Fossils contained within sedimentary rock can offer clues about the age of the rock.
It’s firm and hard like other rock, but it’s actually flowing very slowly, about as slowly as your fingernails grow. The outer core is a liquid layer, made mostly of iron and nickel, that moves around the inner core. This motion causes Earth to act like a giant magnet.
Rocks never die, they just change form. So they don’t have a lifespan. Rocks are always changing form, but too slowly to notice with you’re eyes. In fact; rocks aren’t even classified as living things.
