A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur.
The "weak sphere" - is the soft layer of the mantle where pieces of the lithosphere move. Pieces of the lithosphere that move around on top of the asthenosphere. All the plates fit together like a jigsaw puzzle.
One of the most famous sets of spherical objects carved by an extinct civilization is found in Costa Rica, known as the stone spheres of the Diquís people. These spheres are made of gabbro, which is a volcanic rock that would not naturally form in such a perfect spherical shape.
"Crystal Balls" are usually created from clarified Quartz, meaning the quartz is crushed and heated, impurities removed, and then it is shaped into a sphere. Clarified crystal balls will be very clear, like glass.
Abrasion causes rocks to grind down and become rounder, but does the grinding reduce the size of rocks or is it that smaller rocks are simply more easily transported? First, abrasion makes a rock round. Then, only when the rock is smooth, does abrasion act to make it smaller in diameter.
Agate is an excellent stone for rebalancing and harmonising body, mind and spirit. It cleanses and stabilises the aura, eliminating and transforming negativity. Agate enhances mental function, improving concentration, perception and analytical abilities.
What is the Geosphere? The geosphere is the earth itself: the rocks, minerals, and landforms of the surface and interior. Below the crust - which varies in depth from about 5 km beneath the ocean floor to up to 70 km below the land surface, temperatures are high enough for deformation and a paste-like flow of elements.
Rocks can grow taller and larger
When children grow, they get taller, heavier and stronger each year. Rocks also grow bigger, heavier and stronger, but it takes a rock thousands or even millions of years to change. A rock called travertine grows at springs where water flows from underground onto the surface.A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur.
Egg rocks are smooth, naturally round stones approximately a 3/4" to 2 1/2" in size. Egg rock is a large variety of river rock that is eye catching due to its size and color. The pristine white shine of egg rock looks great on its own or accompanied by other kinds river rocks.
Moqui marbles are small, brownish-black balls composed of iron oxide and sandstone that formed underground when iron minerals precipitated from flowing groundwater. Geologists call them iron concretions.
The water would freeze and expand, causing the rocks to crack. This process is known as mechanical weathering. The downward slope of the region combined with the melting permafrost underneath resulted in the movement of the rocks downward, or mass wasting, to create Boulder Field.
A sphere (from Greek σφα?ρα—sphaira, "globe, ball") is a geometrical object in three-dimensional space that is the surface of a ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk").
The spheres are commonly attributed to the extinct Diquis culture, and they are sometimes referred to as the Diquís Spheres. They are the best-known stone sculptures of the Isthmo-Colombian area.
Dexpan is a cement with amazing 18,000 psi expansive strength when mixed with water. Poured into pre-drilled holes, Dexpan can break concrete and rocks safely and quietly, while providing silent cracking. It is safe, easy and cost effective. AKA Dexpan Expansive Demolition Grout, Rock Splitting Compound Chemical.
Wedges (Plugs) and Feathers
Use wedge and feathers as follows: Position the feathers in the hole so the flat sides of the wedge will be parallel to the line along which the break will occur. Drive the wedge into the slot between the feathers until the rock cracks, or until it sticks in the rock.Options in rocks include digging holes with a backhoe or chipping away the rock, if it's a formation that will chip and break; prying rocks out with a hand bar; or using a hammer drill.
