Draw arrows and label the different horizons in the picture.

In the box, rank these components of soil according to the size of the particles, from largest to smallest:

Sand
Clay
gravel
silt

A sample of soil is taken in a funnel lined with filter paper. The funnel is placed over a measuring cylinder. At $2:00 \mathrm{pm}$, Parveen starts to pour $200 \mathrm{ml}$ of water slowly on the soil. She finishes pouring all the water at $2:10 \mathrm{pm}$. Given here are the readings of water levels in the measuring cylinder at different times. Look at the table and answer the question.

How much water (in $\mathrm{ml}$) was absorbed by the soil?
