marine science vocabulary quiz

📚 Quick Study Guide

• 🌊 Salinity: The measure of the amount of dissolved salts in water. Measured in parts per thousand (ppt).
• 🌡️ Thermocline: A layer in the ocean where the temperature changes rapidly with depth.
• 💧 Density: Mass per unit volume; crucial in ocean currents and layering. Influenced by temperature and salinity.
• 🌀 Coriolis Effect: The apparent deflection of moving objects (like water currents and wind) when viewed from a rotating reference frame (like Earth).
• 📈 Tides: The periodic rise and fall of sea level, primarily caused by the gravitational forces of the Moon and the Sun.
• 🐠 Nekton: Aquatic animals that can swim and move independently of currents. Examples include fish, marine mammals, and squid.
• 🌱 Plankton: Microscopic organisms that drift in water currents. Includes phytoplankton (plants) and zooplankton (animals).
