The given substance combusts following the reaction:
C2H2 + (5/2)O2 -> 2CO2 + H2O
Assume C2H2 is an ideal gas. At STP, 1 mol of an ideal gas
occupies 22.4 L. Given 100.50 mL of C2H2, this means that there is 4.4866 x
10^(-3) mol. Combusting 1 mol of C2H2 consumes (5/2) mol of O2, then combusting
the given amount of C2H2 consumes 0.01121 mol of O2. At STP, this amount of O2
occupies 251.25 mL.

I am not sure why your teacher isn't asking for the layers, but here is the list of layers;
A -(topsoil) Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.
E - (eluviated) - Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.
B - (subsoil) Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.
C - (parent material) The deposit at Earth’s surface from which the soil developed.
R - (bedrock) A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.
Is similar to 3 an you nedd múltiple by 5 and you get 15 for the result
The five main branches of chemistry are organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry and biochemistry. Chemistry can be further divided into many sub-branches that may fall under more than one of the main branches.
The answer to your question would be:: the wind because it carries the sand until it runs into an obstacle
