Understanding Water in Soil

What is one of the key roles of water in soil?

• It acts as a fertilizer.

• It regulates soil temperature.

• It repels plant roots.

• It prevents organic matter decay.

How do nutrients primarily reach plant roots?

• Through soil particles.

• Through air currents.

• Via direct contact with roots.

• By moving through water.

What makes the water molecule dipolar?

• It has no charge.

• It is a single atom.

• It has a positive and a negative side.

• It has two oxygen atoms.

What is the process called when water molecules stick to each other?

• Condensation

• Evaporation

• Cohesion

• Adhesion

What happens when water molecules adhere to soil?

• They lose their dipolar nature.

• They absorb negative charges on the soil.

• They form a solid layer.

• They evaporate quickly.
