The majority of sediments from continents settle in the oceans, especially in areas close to the Coastlines where rivers deposit large amounts of sediment. These sediments can accumulate in continental shelves, deep sea trenches, and submarine canyons.
Approximately 15-20% of sediments eroded from the continents reach beyond coastal regions to the continental shelf and slope. The majority of eroded sediments tend to accumulate and deposit near the coast due to factors such as wave action and currents.
The top 3 continents with the most population are Asia, Africa, and Europe.
No, continents are large landmasses that contain multiple countries within them. Countries are distinct political entities with defined borders and governments, whereas continents are physical geographic divisions of the Earth's surface.
The three continents with the most water per capita are South America, North America, and Asia. These continents have a higher availability of freshwater resources compared to other regions.
Continents are mainly composed of various types of rocks, minerals, and sediments. They consist of a crust layer made of solid rock called lithosphere, which is divided into tectonic plates. Beneath the crust is the mantle layer, which is semi-solid and flows over geologic timescales. The continents also contain landforms such as mountains, valleys, and plains shaped by tectonic activity and erosion.

Sediments settle in layers at the bottom of bodies of water, such as lakes, rivers, and oceans. Over time, as more sediments accumulate, they become compacted and cemented together to form sedimentary rock.
These materials are sediments.
Marine sediments are typically terrigenous in nature, which means they came from the land. Sediments that originate from the continents are called terrigenous.

sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
They settle out as deposited sediments.
Sediments will settle in a horizontal layer. Sediments or sedimentary rock which appears otherwise has been moved by Earth forces.
The sediments that settle out during water treatment are typically removed through a process called sedimentation. In this process, water is allowed to stand still in a tank or basin, causing the heavier particles to settle to the bottom. These settled sediments, often referred to as sludge or floc, are then removed from the water through a scraping or draining mechanism.
