If the climate in an area has very little rainfall, what would be the characteristics of the soil in the area?

The answer is thin, with very little organic material. The reason the soils are thin is that weathering of rocks in such regions is slow due to lack of rainfall. Water is a significant factor in weathering. Additionally, due to the dryness, little vegetation and organisms will thrive. Therefore, chemical weathering of the rocks will be reduced and the humus (organic material) in the soil will be less abundant.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
