Which phenomenon results when the geostrophic balance is disrupted near coastlines?

💡 Explanation

Coastal upwelling increases as the coriolis effect deflects surface currents offshore, and Ekman transport moves surface water away; this removal draws deeper, nutrient-rich water to the surface. The geostrophic balance changes locally because coastal boundaries exert new forces, therefore favoring upwelling rather than broad currents.
