The map illustrates the recorded salinity, which refers to the salt content in the ocean's surface water. What is the most accurate explanation for the salinity levels in the highlighted area?(1 point) Responses The weathering of rocks causes large amounts of salt to enter the ocean in this region. The weathering of rocks causes large amounts of salt to enter the ocean in this region. The flow of a major river enters the ocean in this region and increases the amount of freshwater. The flow of a major river enters the ocean in this region and increases the amount of freshwater. The highlighted regions represent the deepest trenches of Earth's oceans because salt makes the water dense. The highlighted regions represent the deepest trenches of Earth's oceans because salt makes the water dense. The highlighted regions receive more direct sunlight resulting in higher temperatures and evaporation leaving salt behind.
