Question

how do soils form?
o plants cement mineral particles together to form soil.
o weathering breaks rocks into minerals, and plants die and decay.
o plants provide organic matter and minerals to make soil.
o erosion transports mineral particles, and plants die and decay.

Explanation:

Soil formation involves physical and chemical weathering of rocks into minerals, and the addition of organic matter from decaying plants. Erosion is mainly about the movement of soil - related materials rather than the core process of soil formation. Plants don't directly cement mineral particles or provide minerals to make soil in the primary sense of soil - formation.

Answer:

Weathering breaks rocks into minerals, and plants die and decay.
