Why did you need to calculate leaf surface area to determine the rates) of transpiration?

Rate of transpiration is dependent on leaf surface area

Explanation:

Leaf has openings called stomata, which is the structure that allows for transpiration to occur, and they are found in the lower epidermis of leaves. Water escapes through stomata. Smaller leaves tend to have large surface area as they have higher number of stomata compared to larger leaves. Large surface area in smaller leaves would result in relative high rates of transpiration when compared to larger leaves having small surface area.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
