Question

describing the composition of ocean water
where does the salt in oceans come from?
○ rocks and minerals on land
○ rainfall and snowfall
○ dead plants and animals
○ energy from the sun

Explanation:

When rain falls on land, it erodes rocks and minerals. These eroded substances are carried by rivers and streams into the oceans. Over time, this continuous process leads to the accumulation of salt in the oceans. Rainfall and snowfall (\(H_2O\)) themselves are not sources of salt. Dead plants and animals decompose and contribute organic matter but not the main source of salt. Energy from the Sun is involved in processes like evaporation but does not directly add salt.

Answer:

rocks and minerals on land
