A flat seafloor valley filled with sediment is typically referred to as a sedimentary basin or a sedimentary trough. These geological features form when sediments accumulate in low-lying areas of the ocean floor, often due to processes like erosion, river transport, and deposition. Over time, the accumulated sediments can lead to the formation of sedimentary rock layers, which may contain valuable resources such as fossil fuels or minerals. Such valleys play a crucial role in understanding Earth’s geological history and the evolution of marine environments.

The Qu'Appelle Valley was formed during the last Ice Age, primarily through glacial activity and the melting of ice sheets. As glaciers advanced and retreated, they carved out the landscape, creating deep valleys and depressions. The subsequent melting of the glaciers led to the accumulation of water, which filled these valleys, resulting in the present-day Qu'Appelle River system. Over time, erosion and sediment deposition further shaped the valley's features.
New seafloor is created at divergent boundaries, where tectonic plates move apart from each other. This process allows magma from the mantle to rise and solidify, forming new oceanic crust. An example of this is the Mid-Atlantic Ridge, where the Eurasian and North American plates are moving apart. As the plates separate, they create a gap that is filled by rising magma, resulting in the formation of new seafloor.
Often, it is hydrated mantle coming from the Earth's core
Plate movements can create or destroy valleys through processes such as uplift, subsidence, or erosion. For example, when tectonic plates collide, they can push up the Earth's crust, creating mountain ranges and valleys in between. Alternatively, plate movements can also cause valleys to be filled in by sediment deposits or be eroded away by rivers and glaciers.
HUMAN
The Valley and Ridge physiographic province in the eastern United States was formed through tectonic processes including the collision of tectonic plates, which caused the Appalachian Mountains to rise. As the mountains eroded, sediment filled in the valleys between the ridges, creating the characteristic alternating pattern of valleys and ridges that we see today.

a mold is an impression of an organism. a cast is a mold filled with sediment
Mold
Flooded glacial valleys are valleys carved out by glaciers during the last Ice Age which are now submerged under water. These valleys can form deep fjords, where seawater has filled in the glacially-carved depressions. Examples include the fjords of Norway and Alaska.
A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.

They are carbonate deposits formed by dripping water in air-filled cavities.
it was formed when the earth's crust expanded subsided and filled with sediment between the carboniferous and triassic
