What's the difference between stalactites and stalagmites? What exactly is the difference between stalactites and stalagmites? Which one hangs above and which one stands up from the ground? Stalactites and stalagmites are what are known as speleothems, deposits of minerals that form into cave structures and line the insides of a cave. Stalactites are the formations that hang from the ceilings of caves like icicles, while stalagmites look like they're emerging from the ground and stand up like a traffic cone. Some may take thousands of years to form, while others can grow quite rapidly.

What's the difference between stalactites and stalagmites? Soon enough, a stalagmite will form in a conelike shape. This is why you usually find stalactites and stalagmites in pairs, and sometimes they'll even grow together to form one big column.

Meteorite (Redirected from NWA meteorites) A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the Earth's atmosphere and impact with the Earth's surface or that of another planet.

Sty A sty is a bump that forms on or in the eyelid as the result of a blocked gland. The word sty can also be spelled stye. There are two distinct types of styes: hordeolum and chalazion.Each has different causes and treatments. A hordeolum is a blockage of one of the sweat glands or oil glands found in the skin of the eyelid, while a chalazion is a blockage of a meibomian gland, which is a special oil gland unique to the eyelids.here are two distinct types of styes: hordeolum and chalazion.

- Stalagmite. Stalagmites are corresponding formations on the floor of caves to stalactites. Stalagmites rise from the floor in a build-up of calcium carbonate over time, from mineral-bearing water dropped from the roof of the cave.The term stalagmite comes from the Greek word, stalagma, to “drop”.talagmites are corresponding formations on the floor of caves to stalactites. Stalagmites rise from the floor in a build-up of calcium carbonate over time, from mineral-bearing water dropped from the roof of the cave.

What is a Stalagmite? A stalagmite is a type of rock formation which appears in caves. It is considered a type of speleothem, or cave deposit: you may also be familiar with stalactites, another type of speleothem. Stalagmites grow very slowly over hundreds of years, and they can take on fantastical dimensions and shapes as they develop.

Human Physiology/Print Version A kidney stone, also known as a renal calculus or nephrolith, is a solid piece of material which is formed in the kidneys from minerals in urine. Kidney stones typically leave the body in the urine stream, and a small stone may pass without causing symptoms.alcium and oxalate in the diet play a part but are not the only factors that affect the formation of calcium oxalate stones. Dietary oxalate is an organic molecule found in many vegetables, fruits, and nuts. Calcium from bone may also play a role in kidney stone formation.

What's the difference between stalactites and stalagmites? Ca (HCO 3) 2 is known as calcium bicarbonate, and the water carries the substance, basically dissolved calcite, through the cracks of the roof of a cave. Once water comes into contact with the air inside the cave, however, some of the calcium bicarbonate is transformed back into calcium carbonate, and calcite starts to form around the crack. As water continues to drip, the length and thickness of the calcite grows, and eventually a stalactite forms on the ceiling.

Stalactite and stalagmite Stalactite and stalagmite. Stalactites and stalagmites are two types of rock formations typically found in caves. Stalactites hang from the ceiling, much like icicles. Stalagmites grow from the floor. Both are formed when minerals like calcium carbonate precipitate out of dropping water. The timeframe for formation of stalactites and stalagmites is a subject of dispute.

Meteoroid A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. Meteorites are sometimes, but not always, found in association with hypervelocity impact craters; during energetic collisions, the entire impactor may be vaporized, leaving no meteorites.

Igneous Rocks: How Are They Formed? Hypabyssal (Subvolcanic) Igneous Rock: Hypabyssal rock is a form of intrusive igneous rock that solidifies at medium to shallow depths within the crust, usually in fissures as dikes and intrusive sills. These rocks typically have an intermediate grain size and texture between that of intrusive and extrusive rock.

STONE METEORITES Visible inside most stone meteorites are tiny, glassy, spheres known as chondrules. Forged at the very dawn of the Solar System, these chondrules are far older than our own planet. Some stone meteorites, known as carbonaceous chondrites, have been found to contain water, salt, and even amino acids. In the distant past, these meteorites may have carried the very building blocks of life to Earth.

Halite Halite. Halite is a mineral commonly known as table salt, rock salt or simply salt. Halite is composed of sodium and chlorine in equal proportions (NaCl). Rock salt and halite are not exactly synonymous terms.Halite is a mineral, rock salt is a type of rock that is predominantly composed of halite.alite crystals demonstrating perfect cubic cleavage. Halite crystals demonstrating perfect cubic cleavage. Halite crystals covering a quay on the Atlantic coast in Morocco. These salt crystals formed when seawater evaporated. Pure halite is a transparent mineral.

- Stalagmites are rock formations found in caves. Along with stalactites, stalagmites are speleothems, or cave deposits that form slowly over hundreds of years. People should not touch stalagmites, else they could disrupt the deposition of mineral and halting their growth. Stalactites and stalagmites are found inside most caves.

Talc A block of talc. Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water.This is known as talc carbonation or steatization and produces a suite of rocks known as talc carbonates.alc is a common metamorphic mineral in metamorphic belts which contain ultramafic rocks, such as soapstone (a high-talc rock), and within whiteschist and blueschist metamorphic terranes.

Pluton In geology, a pluton is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the surface of the Earth. Plutons include batholiths, stocks, dikes, sills, laccoliths, lopoliths, and other igneous bodies. In practice, pluton usually refers to a distinctive mass of igneous rock, typically several kilometers in dimension, without a tabular shape like those of dikes and sills. Batholiths commonly are aggregations of plutons.

- Oxalates are naturally-occurring substances found in plants, animals, and in humans. In chemical terms, oxalates belong to a group of molecules called organic acids, and are routinely made by plants, animals, and humans. Our bodies always contain oxalates, and our cells routinely convert other substances into oxalates.n chemical terms, oxalates belong to a group of molecules called organic acids, and are routinely made by plants, animals, and humans.

Stalactite and stalagmite 1 Stalactites hanging from the ceilings of caverns commonly exhibit a central tube or the trace of a former tube whose diameter is that of a drop of water hanging by surface tension. A drop on the tip of a growing stalactite leaves a deposit only around its rim.
