Chemical and mechanical weathering causes the decay and some discoloration. Elements leached from other rocks could contribute to staining.

What is a material that formed from the decay of ancient organisms and is used today as a source of energy?
That would be fossil fuels.
When an unstable Bromine nucleus undergoes alpha decay the nucleus formed is that of?
If a bromine atom underwent alpha decay, the result would be an arsenic atom with a mass number four lower than the original bromine atom. I did a little research on this, however, and it appears that there are no bromine isotopes that undergo alpha decay. I have provided a link to the interactive table of nuclides.
What is the source of heat in the Earth's interior?
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
Why does decomposition occur?
Decomposition occurs because of oxygen and bacteria. Without decomposition the earth would become dry and lifeless. It a series of things that happen. Like the food chain if one fails they all.
What is the type of radioactive decay in which positive particles are given off?
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
When are potatoes not good?
When a potato begins to decay is is time to discard it. Signs of decay include mold, discoloration, rotting etc.
Is another word for decay.?
Rot and decomposition are words for decay. Another word for tooth decay is cavity. Cavities happen as a result of the production of acid by bacterial fermentation of food debris accumulated on the tooth surface.
Why does mixing a compost pile speed the process of decay?
The decay process needs oxygen for it to happen. The surface of the compost heap will decay faster than the material 'buried' deeper in the pile. Regular mixing of the compost ensures air gets right into the heap - speeding up the decay process.
Why do fungi and bacteria decay materials?
Fungi and bacteria eat things. Decay is caused by the growth and reproduction of these decay organisms, which are eating the material which is decaying. You don't see individual bacteria at work because they are microscopic, and you don't clearly see fungi at work, because most of what they are doing is hidden, but you see the result, in the form of decay.
What role does the decay of radioactive elements deep within Earth play in the formation of a volcano?
The internal heat of the Earth is thought to be about 20% residual heat from planetary accretion and about 80% from radioactive decay. The internal heat provides heat to liquefy magma and send plumes of the hot material upward, through the mantle, to the surface. This material comes out from the surface in various forms, such as lava, and thus forms volcanoes.
What is chilling injury in food?
It's when crops are damaged by low temperatures. The tissues weaken in plants that are sensitive to low‐temperature exposure, causing surface pitting, or discoloration, internal breakdown, failure to ripen, growth inhibition, wilting, loss of flavor, and/or decay.
What does the half life of a radioisotope correspond to?
The length of time required for half of a sample of radioactive material to decay
How are the types of decay different?
The types of decay are different because every material has its own nucleus unstability
Does alpha decay naturally?
Yes, alpha decay occurs naturally, that is why radioactive material is dangerous, because we can't simply "turn off" the radioactive decay.
Is eating sand bad for you?
Eating sand can greatly erode tooth enamel, causing decay, cavities, sensitivity, discoloration, and pain. This is because of the abrasiveness of the sand.
In the description of the exterior of the house of usher which word suggest the presence of decay in the structure?
The word that suggests the presence of decay in the structure of the house of Usher is "discoloration." This term implies a change in color due to age or damage, hinting at the deterioration of the house.
What counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.
