Soil is a natural body consisting of layers (soil horizons) of primarily mineral constituents of variable thicknesses, which differ from the parent materials in their morphological, physical, chemical, and mineralogical characteristics. In engineering, soil is referred to as regolith, or loose rock material. Strictly speaking, soil is the depth of regolith that influences and has been influenced by plant roots.
Soil is composed of particles of broken rock that have been altered by chemical and mechanical processes that include weathering and erosion. Soil differs from its parent rock due to interactions between the lithosphere, hydrosphere, atmosphere, and the biosphere.It is a mixture of mineral and organic constituents that are in solid, gaseous and aqueous states. Soil is commonly referred to as earth or dirt; technically, the term dirt should be restricted to displaced soil.Soil forms a structure that is filled with pore spaces, and can be thought of as a mixture of solids, water and air (gas). Accordingly, soils are often treated as a three state system. Most soils have a density between 1 and 2 g/cm³.Little of the soil composition of planet Earth is older than the Tertiary and most no older than the Pleistocene.
Topography is an important factor for soil formation
Do you mean the importance of soil formation? This seems like a strange question. Can you rephrase it?When you realize that just about every bit of food you've ever eaten or will ever eat originated in soil, you might consider soil formation important.
Climate is the most influential control of soil formation. source: Tarbuck Lutgens TASA Earth Science Twelfth Edition. page94
it is responsible because it helps the soil to get the amount of nutrients needed, so that if a plant is place there it can take some of the water from the soil in order to survive.

Water is important for soil so that the soil can be health and grow plants!
water usually does that
