GEOL 101 Chapter 7: Sedimentary Rocks. STUDY. PLAY. Sedimentary Rocks. Products of mechanical and chemical weathering Types: Detrital ... Ice expanding in a crack in the road, creating a pothole Tree roots extending and cracking a sidewalk. ... You find a sedimentary rock that has all its flat particles aligned in a parallel. From this you ...

Key Concept Rock is broken down into smaller pieces by mechanical and chemical weathering. • Ice, water, wind, gravity, plants, and animals can cause mechanical weathering by breaking rock into pieces. • Water, acids, and air can cause chemical weathering of rocks.

Use a crowbar and put another rock under it so that sections of it are unsupported. Now whack it with the sledgehammer a few times. If you get lucky, it will have a crack in it and you can break it into pieces.

When chemical reactions dissolve the minerals in rocks or change them into different minerals.

But let's see how the explosion leads to the rock breakage. The explosion is a chemical reaction that produces a shock wave and a large amount of gas that has high temperature and high pressure. ... the shock wave creates and expands the micro fractures in the rock mass and initiates the breaking process. Then the gas, expanding the drill ...

Bri star. It offers many benefits to concrete or rock demolition projects over that of traditional demolition methods. Worksites are often located in areas where disruptions must be kept to a minimum, and safety, noise and environmental constraints limit the use of jackhammers, explosives or heavy machinery.

New rock, concrete breaking solution eliminates noise, gases, flying rock and vibration shockwaves. The cartridge contains a nondetonating chemical compound, which, when ignited, reacts instantaneously to produce high volumes of harmless gas, mainly consisting of nitrogen, carbon dioxide and water vapour.

Weathering Clay Minerals: ... causing expansion of the fracture. Growth of plants can break rock look at the sidewalks of New Orleans for example. Animals burrowing or moving through cracks can break rock. ... Thus, the smectites are expanding clays. The most common smectite is Montmorillinite, with a general chemical formula : (½Ca,Na)(Al ...

FreezeThaw Weathering. When the water in the cracks freezes, it expands by 9 to 10 percent, exerting pressure on the rock, according to BBC Bitesize. This action can widen the cracks in the rock, and when the temperature rises above freezing, the ice thaws, allowing the water to seep further into the cracks.

That's where the CO2 in the soda comes into play. The soda, a carbonated liquid to begin with, contains lots of pressurized CO2. When the Pop Rocks are dropped into the soda, some of the gas in the soda collects in gazillions of bubbles on microscopic nucleation sites .

Nonexplosive demolition agents. To use nonexplosive demolition agents in demolition or quarrying, holes are drilled in the base rock as they would be for use with conventional explosives. A slurry mixture of the nonexplosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands,...

When that water expands, the rock is crunched between two expanding pieces of ice instead of being forced apart into separate pieces. Another type of mechanical weathering is called salt wedging. When it rains and water flows everywhere, it usually has ions and salts dissolved inside.

The device works on the principle of breaking rock (or like structural materials) in tension through rapidly expanding gas pressure. As such, the technology is much more efficient than slowly expanding cements and chemicals.

Chemical weathering is the alteration of the rock into new minerals. Both pathways constitute weathering, but one process may dominate over the other. .

Chemical weathering is a rockrotting process. It changes rock minerals when acidic water dissolves carbonate rocks or iron minerals are exposed to oxygen and form rust. In biological weathering, living organisms speed up the process of rock breakdown.

SCDAs are powdery materials that will expand considerably when mixed with water. This expansion, when occurring under confinement, generates significant expansive pressures. These pressures are sufficient to break up rock and concrete when the SCDA is .

Lichen break down rock as they grow, they trap moisture and organic compounds underneath, and seeps into the cracks into the rocks. On cold days, the water expands; eg. ice an.d fragments the rock. I'm not too sure but maybe also the lichen's waste but that's a guess..
