Answer:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms. Weathering occurs in situ (i.e., on site, without displacement), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.

Earths lithospere is solid and sits on top of the softer asthenosphere.
Yes, plants are absolutely alive. They may not be conscious, sentiment beings, but they still perform cellular respiration, make waste products, and generate biomass (get bigger).
Hope this helps.
