Lithosphere and hydrosphere: oxygen
Radium is a highly radioactive alkali earth metal, and it can be found in trace amounts in some water sources and in some soil or rock samples. That means this stuff isn't found in the atmosphere. (It may be in some dust, but not likely.) But it will be found in some places in the lithosphere (the ground or the earth) or the hydrosphere (the water). Radium is associated with the radioactive decay of uranium, so where traces or deposits of uranium ore are found, this stuff will be around. A link to the Wikipedia article on radium is provided.
It can be harmful in large amounts, but is relatively safe in low amounts.
There is normally no life that breathes in the stratosphere. In the troposphere, both plants and animals suffer when significant amounts of ozone are present.
Yes but in relatively low amounts
The atmospheric layer containing water is troposphere. It contains water vapor.
It is a system of agriculture in which relatively small amounts of capital or labour investment are applied to relatively large areas
Relatively small amounts of energy are released or absorbed.
Yes it is. The hydrosphere(mostly ocean water) is made up of H2O and other chemicals such as NaCl(salt), and smaller amounts of Mg, S, Ca, and other elements as ions. (Magnesium, Sulfur, Calcium etc.)
Relatively large amounts of the kidneys have shrunk.
"Trace gasses" are elements which are present in a sample, but in relatively very small amounts.
Calcium, phosphorus, sodium, chloride, potassium, magnesium, and sulfur.
It's the troposphere because :The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing most of its weight into this lowest layer.
"Trace elements" are elements which are present in a sample, but in relatively very small amounts. "Trace gasses" probably means gasses which are present in a sample, but in relatively very small amounts. the gases in earths atmosphere that take up less than 1% volume.
It's a corrosive
