Model Answer
Two features of arid soils:
- Sandy and saline: Arid soils are generally sandy in texture and saline in nature. Due to high temperature and rapid evaporation, they lack humus and moisture.
- Kankar layer: The lower horizons are occupied by Kankar (calcium deposits) which restricts infiltration of water into the soil.

Explanation
- The question asks for any two features, so two clearly distinct points are enough — don't write more.
- Examiners expect specific textbook terms: sandy texture, saline, Kankar layer, lacks humus/moisture. Using these exact terms scores full marks.
- Colour (red to brown) can also be mentioned as a feature if needed as a substitute point.
