The two process that are most often responsible for the breakdown of rock into soil particles are choose the two that apply (1. accretion (2. weathering (.3 deposition (4. erosion

(2. weathering

(4. erosion

Explanation:

Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material.

The three types of weathering, physical, chemical and biological.

Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location.

Answer: the two processes that are most often responsible for the breakdown of rock are:

-Weathering

-Erosion

Explanation:

Weathering is defined as the breakdown of rock into smaller particles by the action of rain, high temperature and some biological factors. The three classification of Weathering are physical, chemical and biological. Physical Weathering is the breakdown of rocks through the action of direct contact with some atmospheric conditions like heat, water etc. Chemical weathering involves the use of atmospheric chemicals.

Erosion deals with the washing away of the outermost region of the earth surface from one region to the other. Erosion breakdown rock gradually into soil particles through the action of wind and water flow. Erosion involves movement while Weathering do not involve movement. Erosion destroys soil structure and fertility.
