yes
Magnetic force does not break down rocks in nature. Rocks are typically broken down by mechanical weathering (e.g. frost wedging, root growth) and chemical weathering (e.g. oxidation, dissolution).
Two processes that can break down rocks are weathering, which is the breakdown of rocks into smaller pieces by natural elements like sunlight, water, and wind, and erosion, which is the transport of these smaller rock fragments by forces like water, ice, or wind.
the process is called weathering when the rocks break down
Some common tools that nature uses to erode rocks include wind, water (rivers, waves, precipitation), ice (glaciers), and vegetation (roots breaking down rocks). Over time, these forces can break down rocks into smaller particles through processes like abrasion, dissolution, and weathering.
soil
Water can erode rocks. This is particularly true if it moves down a steeply inclined area and there is a lot of it. Also consider ocean waves that break ashore. It can also get into cracks and crevices in rock and freeze, forcing the rock to crack apart.
Weathering
none
Yes
Erosion is the main force that acts on rocks to break them down into sand. Water getting into cracks, freezing and expanding also helps to break down rocks.
