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.

A rock is the hard, solid part of the Earth that is not soil or metal. Rocks can be different colors. Some rocks are smooth. Other rocks are very rough.

The cycle has no beginning and no end. Rocks deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them. Several processes can turn one type of rock into another type of rock.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
