Which of the following statements is incorrect?

• A. All living things require air to breathe
• B. We can feel air but we cannot see it
• C. Moving air makes it possible to fly a kite.
• D. Air is present everywhere but not in soil.

Answer 1

The correct option is D

Air is present everywhere but not in soil.

The correct option is D.

Explanation of the correct option:

1. Air is everywhere.
2. Soil absorbs water due to its water holding capacity.
3. The empty spaces of soil are filled with water.
4. This makes the soil moist and fertile for crops.
5. Hence, there would be no air in the soil.

Explanation of the incorrect option:

Option A:

1. All living organisms need air for breathing.
2. Oxygen is also important for cellular respiration.
3. Hence, in the absence of air life can't exist.

Option B:

1. The air contains dust particles that carry the light waves.
2. They absorb small spectra of light.
3. As no light wave is reflected, air has no colour.
4. Therefore, we can feel it but can't see it.

Option C:

1. The upward force that propels a kite into the air is referred to as a lift.
2. Lift is produced by differences in air pressure.
3. The kite is designed and angled in such a way that air makes it fly.

Final answer: Air is present everywhere but not in the soil is the incorrect statement.
