Question 1.
What is gravitational potential?
Show hintHide hint
Think about how water at different heights behaves.
Question 2.
Define matric potential.
Show hintHide hint
Consider what happens when water sticks to soil.
3Question 3.
What is the main characteristic of gravitational potential?
- It is always negative
- It is related to position above a reference point
- It has no effect on water movement
Show hintHide hint
Consider how elevation influences potential energy.
4Question 4.
Matric potential is typically represented by which type of value?
- True
- False
Show hintHide hint
Think about how water interacts with soil grains.
Question 5.
A field has water at different depths. If the gravitational potential at the surface is 0, calculate the gravitational potential at 10 meters depth.
Show hintHide hint
Think about how depth influences gravitational effects.
Question 6.
Discuss how increasing salinity in soil affects the osmotic potential and relate that to agricultural practices in arid regions.
Show hintHide hint
Consider how plants struggle in saline environments.
