Class 8 Science Chapter 1 Extra Questions

What do you understand by levelling?

After ploughing the soil is still in large clumps. The large clumps of the soil are broken and the soil is pressed to make it even. This is called levelling.

Why should we not sow seed too deep?

If the seeds are sown too deep, they will not get enough air for respiration. Germination will be adversely affected, because the shoots will have to struggle hard through the layers of soil to reach sunlight and fresh air.

What is meant by transplanting?

Seeds of rice and many vegetables such as tomatoes, chillies and onions are not sown directly in the soil. Instead, they are first sown in a nursery and allowed to grow into small plants called seedlings. Healthy seedlings are then picked out and transferred to the field. This is called transplanting.

What is irrigation?

Irrigation is the most important activity in crop production. Water is necessary for the survival and proper development of crop plants. The supply of water to crops at different intervals is called irrigation.
