Answer:
The three sand are similar in composition, since all are formed 90% by quartz. They are also similar in roundness, as they all have large particles that allow a very sandy soil with low water retention.
Explanation:
The desert area of the river and the beach have a very similar composition, since 90% of these sands are composed of quartz. however, the similarity does not mean that these sands are the same, as they are not, since the sands of the beach and the river may have a little more material, such as animal remains, making these sands also have carbon in composition, something that desert sand has in less quantity.
In addition, both sands have large particles that promote strong aeration in the soil, but a very rapid loss of organic matter.
The length is 88 cm, multiply the width by two and subtract it from the whole perimeter. Then divide the whole perimeter again by two to find the length of one side.
Answer:
Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.
