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
At extreme latitudes, the midnight sun is usually referred to as polar day. That is in Winter.

In divergent boundaries, plates move away from one another, often causing volcanic activity. The cooled magma is able to form islands such as the ones on the Aleutian archipelago.
*I don't think any of these are actual types of mountains. <em>Arc contient </em>and <em>Andean</em> aren't even real things.
As for your second question:
There are two main types of rocks in the Earth's crust.
Granite is less dense and rises higher, usually above land in continental crust.
Basalt is denser and so it will sink lower and form oceanic crust.
However, there is a layer of sediment on top of that crust. (sand, gravel, etc.)
