Answer:
The A horizon will be relative large with a high content of sand.
Explanation:
A desert, as it is, is covered with very fine sediments in most cases, ranging from medium and small rocks to fine sand. If the climate conditions were to change where there is a desert and the climate became more temperate, the soil will change as well relatively quickly. What is actually now the surface of the deserts will become the new soil's A horizon while on top of it a 0 horizon will form.
The A horizon in a former desert will become very fertile and it will be able to support lush vegetation. This will be the case because it will have a very high content of sand, thus it will be very airy and soft. The newly formed O horizon made out of biomass on top of it will wash away to the A horizon, increasing its fertility further by adding a big amount of decomposed biomass to it.

Explanation:
Electromagntic wave, such as an X-ray.
Explanation:
- Electromagnetic wave does not require any medium to travel. These waves propagate outwards from the source.
- They can travel even through the vacuum of outer space.
- The major source is the sun which emits radiation in the form of the Electromagnetic spectrum.
- These waves travel through oscillating electrical and magnetic fields generated by the oscillating charged particles.
- These waves oscillate in the perpendicular direction of planes concerning each other and are in form.
- Electromagnetic waves travel at speed of light.
