Formation of sedimentary rocks
1- Sediments are mixed + mud + remains of plants and animals at
the bottom of (ocean, lakes / deserts) forming layers.
2- Over the time, more and more layers press down forming
sedimentary rocks.
Glaciers are rivers of ice / snow move slowly.
It can help in erosion as they carry large rocks.
The evidence left by erosion can
be seen after 100 / 1000 / 1000,000
years from its occurrence.
