As sediments approach a continent, they typically change character due to various geological and environmental processes. Near the shore, sediments are often coarser and more angular due to wave action and stronger currents that can transport larger particles. In contrast, as sediments are carried further out to sea, they tend to become finer and more rounded, as they are subjected to prolonged erosion and sorting by water movement. Additionally, biological activity and chemical processes in shallow waters can further alter sediment composition, leading to distinctive features like clay-rich deposits near continental margins.
As one approaches a continent from the ocean, sediments change primarily due to the transition from marine to terrestrial environments. In deeper ocean areas, sediments are often fine-grained and composed of organic materials and planktonic organisms. However, as you near the coast, sediments become coarser and are influenced by riverine inputs, erosion, and coastal processes, resulting in a mixture of sand, silt, and clay. Additionally, factors like wave action and tidal currents further shape sediment composition and distribution along the continental shelf.

The two processes that can change sediments into rocks are compaction and cementation. Compaction occurs when sediments are compressed by the weight of overlying sediments, reducing the pore space between particles. Cementation happens when minerals precipitate in the pore spaces, binding the particles together into a solid rock.
Sediments can change into sedimentary rocks through processes like compaction and cementation. They can also be eroded and transported to new locations by forces like wind and water.
During transport, the physical characteristics of sediments change due to processes like abrasion, sorting, and compaction. As sediments are moved by water, wind, or ice, they tend to become smaller and rounder as edges are worn down. Sorting occurs as sediments are separated by size and weight, often leading to a more uniform grain size in the deposit. Additionally, compaction can increase density and alter the arrangement of particles as sediments settle in new environments.

No country can change the continent it is on. Therefore Greece was and is on the European/Eurasian continent.
The get compacted with burial and dewater. The grains from which they are made become cemented together and the sediments become sedimentary rocks.

Erosion
Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.
Yes. Any rock can be weathered into sediment.
