Try these first

1. 1.

   What is redistribution in soil?

   Hint

   Think about how water behaves after it rains.

2. 2.

   What role does capillarity play in soil?

   Hint

   Consider how water moves in a sponge.

3. 3.

   What happens to water after it infiltrates the soil?

   • It stays in the same place.
   • It redistributes through the soil.

   Hint

   Think of how water goes up a straw.

   Hint

   Consider the characteristics of sandy soil.

6. 6.

   Evaluate the role of soil compaction in affecting water redistribution and suggest a solution for improving water infiltration.

   Hint
