Weathering and run-off
Rain slowly dissolves minerals from rocks – a process called weathering. These minerals eventually get washed into the sea, where some minerals, such as calcium carbonate, add to sediments at the bottom of the ocean. A lot of organic matter from the soil also gets carried to sea by rivers.
