Siberia covers the majority of Russia
The frequency and speed of the wind
The energy of the waves hitting the shore
The hardness of the rock that makes up the shoreline
All of these will determine the shape and how fast a cliff is formed, such as the speed of the wind and water, as well as how hard a rock is, will shape how the rock looks like.
For example, if the wind and waves are traveling extremely quickly, and the rock is made of sand, the rock will break much quickly.
Hope this helps
The answer is; plankton
The major group of plankton that contribute to earth’ crude oil are phytoplanktons because of their great numbers – even though they are microscopic. They are the base of the food chains in the oceans because they are the main primary producers. Examples of phytoplankton are the dinoflagellates, cyanobacteria, diatoms and blue-green algae.
