<span>The three properties of components of the universe are frequency,wavelength and Intensity can be determined using electromagnetic radiation.Frequency is defined as the number of cycles per second, and it's unit is Hertz (Hz).Formula is E=hν. Wavelength is the distance of one full cycle of the oscillation.The wavelength related to frequency formula is c=λν.Amplitude is the distance from the maximum vertical displacement of the wave to the middle of the wave. Then amplitude tells about the brightness of the wave.</span>

Answer:
The result of loss of topsoil are loss in fertility of soil, loss of water, crop production and hardened soil surface. Therefore, the correct answer to the above question is option A, B, C and D.
Explanation:
When there is a loss of top layer of soil from the earth by any means, natural or artificial, it is known as soil erosion. The soil from one place gets detached and is transported to another area. Planting more and more trees is the one of the way to stop soil erosion as the roots of the plants hold the soil.
When the soil from area is removed there is a loss of production in crop due to various reasons. The most fertile part of the soil occurs in the uppermost part. Therefore, its removal has negative impact.
the answer could be breath oxygen or respond to stimuli. Hope this helps!
