What occurs when rock exposed to oxygen elements in the air?
oxidation
How does oxygen in the atmosphere differ from oxygen in rock and minerals?
Atmospheric oxygen tends to be elemental oxygen (O2). Oxygen in rocks and minerals is chemically combined with other elements to form compounds called oxides.
When is a rock considered an ore?
An ore is a rock that bears minerals containing valuable elements. Most rock can be considered to be an ore although the classification is usually reserved for rock that has sufficient concentrations of elements to make it worth mining and separating.
Is chalk an element?
If you mean the sedimentary white rock, then that is Calcium Carbonate which has the elements Calcium, Carbon and Oxygen. If you mean blackboard chalk, then that is Calcium Sulphate which has the elements Calcium, Sulphur and Oxygen.
What is sentence with the word elements?
"Fire, wind, water, and rock are all elements of the Earth."
What occurs when rock exposed to oxygen elements in the air?
oxidation
Are oxygen and silicon the most common rock forming elements?
Yes.
What rocks are elements?
The major rock forming elements are oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Many other metallic and non-metallic elements are also found in rocks. Depends on the rock.
What two elements can be processed from material on the moon.?
Both hydrogen and oxygen can be processed from Moon rock
How does oxygen in the atmosphere differ from oxygen in rock and minerals?
Atmospheric oxygen tends to be elemental oxygen (O2). Oxygen in rocks and minerals is chemically combined with other elements to form compounds called oxides.
Why are most rock-forming minerals silicates?
Most rock forming minerals are silicates because of the preponderance of the elements silicon and oxygen in the crust and mantle.
What happens to the rate at which a rock will weather when it is broken up and why?
The rate of decomposition of the rock will increase when it is broken up because there is more surface area exposed to the elements weather) that can erode the surfaces.
What does chemical and physical weathering have in common?
Physical weathering physically breaks down the rock, whereas chemical weathering breaks down the rock through chemical changes. For example, physical weathering could break down rock through ice wedging, which occurs when water seeps through the cracks in the rock, freezes, and expands, causing the rock to crack. Chemical weathering could be when oxidation (rusting) occurs, when metal is exposed to water and oxygen. Either way they both break down rock.
What does Jack say about the uppermost rock in the pile?
Jack says that the uppermost rock in the pile is the most exposed to the elements and experiences the most wear and tear.
What rock has erosion?
Any rock that is exposed to it.
Which relative concentrations of elements are found in felsic rock?
A high concentration of aluminum, and a low concentration on iron.
When is a rock considered an ore?
An ore is a rock that bears minerals containing valuable elements. Most rock can be considered to be an ore although the classification is usually reserved for rock that has sufficient concentrations of elements to make it worth mining and separating.
