Answer 1

Do you want me to pick an answer for you, or would you like a quick refresher so you can decide confidently?

Quick refresher (1–2 minutes):
- What soil is: a mixture of mineral particles, organic matter, water, air and living organisms.
- Key things to describe: texture (sand/silt/clay), structure (granular/crumb/blocks), color (use Munsell if available), depth/thickness, horizons (O, A, E, B, C), drainage, pH, and organic content.
- How it forms: weathering of parent rock + added organic matter, modified by five main factors — Climate, Organisms, Relief (topography), Parent material, Time (mnemonic: CLORPT).
- Simple field checks: ribbon test for texture, color and structure observation, smell (organic/anaerobic), basic pH strips, squeeze/mud test for drainage.

If you read that and feel ready to answer the poll:
- Choose A (Very confident) if you could clearly describe soil texture, horizons and the CLORPT factors.
- Choose B (Somewhat confident) if you understand the basics but aren’t comfortable with field ID tests or horizon terminology.
- Choose C (Not confident) if you’d like more explanation or practice.
