contains more than 30,000 kg of carbon per hectare.

END OF TEST
On your worksheet
1. The soil is a four letter word, truly but is not rubbish so the statement is .. (True)
2. A soil with 25 cm depth , bulk density 1450 kg/m3, and area of 1 ha = 10,000m2
Has volume of area x depth = 0.25 m x 10000m2 = 2500m3
Mass of soil per ha= density x volume = 2500 m3 x 1450 kg/m3=3,625,000 kg/ha
2% organic carbon = 2/ 100 * 3625,000kg/ha
= 75,500 kg /ha
75,500 kg/ha is greater than 30, 000 kg . The statement is therefore True.
3. Lava is the term given to magma when it reaches the surface of the earth. Plutonic rocks form
below the surface of the earth. Therefore plutonic rocks cannot form from lava. Therefore the
statement is False
4. Kaolinite has a CEC that ranges from 3 to 15 cmol/kg. The statement is
5. This is statement is true because I wrote it ( joke ) (True)
With the above result what you will enter on the answer booklet is as follows:
