      Rivers from Land, add minerals to sea water. Discuss how?

    Answer:

      The soil is made up of rocks (which are aggregation of minerals). Due to heavy rains and hoods the unprotected top soil gets washed into the streams and rivers. Feat moving water removes the top soil of the fields and near the river banks and carries it away with it. Almost all the rivers along with the eroded soil and mineral particles fall into oceans and seas thus adding mineral content to them.
