where does the salt in oceans come from?
glaciers contain salt and melt into the ocean.
pollution from trucks adds salt into the ocean.
minerals from the land are washed into the ocean.
decomposing fish and plants in the ocean increase salinity.

Explanation:

• Glaciers are made of freshwater ice and do not contain salt.
• Pollution from trucks is not a significant source of ocean salt.
• Minerals from the land, such as sodium and chloride, are washed into the ocean by rivers and other runoff over time, contributing to the salt content.
• Decomposing fish and plants in the ocean do not significantly increase salinity compared to the input of minerals from land.

Answer:

Minerals from the land are washed into the ocean.
