both silt and rotting leaves are a component of topsoil.
If you have a really close look at a handful of the soil under the top layer (called humus and composed mainly of fallen leaves) you'll see that there are lots of fragments of everything that is above you. Sticks, leaves, flowers, seeds, seed cases, branches, bits of animals and insects...
Then if you have a look at the "dirt" itself, you'll see that it consists of a whole myriad of particle sizes, from rather large stones down to the smallest particles which are found in clay. Clay is made up of bits which are about 2 / 1000ths of a millimetre in diametre. Between the stones and clay are a whole lot of others, including silt.
Silt is simply a soil particle which is smaller than sand but bigger than clay. It's usually associated with waterways because it's easy to see and is deposited in large amounts on the banks of rivers and streams. Silt deposits happen in different places to similar deposits of clay and sand due to the dynamics of the watercourse: the strength of the flow, the season, the shape of it's course and the amount of water entering from the surrounding lands.
Hope this clears things up!

silt is from rivers it does end up in the soil with changing river courses ,but is limited to location,
rotten leaves is what soil is made up of everywhere
trees make there own soil in their life time ,with the leaves it discards,that is what top soil is ,and this is what plant growth needs
even the soils we use for agriculture is on lands where used to be forrests before,
desserts have little plant growth and plants that can live in sand because there is no soil

rotting leaves are.
i don't think silt is, because that has to do with sand, i think.
but rotting leaves are because they are decomposing.
definately.

Soil is composed of decaying organic material. Orgainic material is anything that is/once was alive.
