Water makes up more than half of our body weight and is essential for life. Our bodies need water to regulate temperature and remove waste. Water is also necessary for plants, animals, and ecosystems to survive.

Question: How is freshwater different from salt water? Clues: • Freshwater has less salt and other dissolved solids. • Salt water has a higher density than freshwater. • Salt water has a higher boiling point than freshwater. In pairs: Select and solve one of the tasks: A. Draw a Vinn diagram comparing and contrasting freshwater and salt water. B. Create a poster to explain the differences between freshwater and salt water.

Ocean currents are large, ongoing movements of water in the ocean. These currents are caused by forces like wind, temperature, and the salinity of the water. Ocean currents transport energy, heat, and nutrients around the planet.

Waves are created by wind moving over the surface of the ocean, which causes the water to move in a circular motion. Currents are horizontal movements of seawater caused by differences in density, temperature, and salinity. Tides are the rise and fall of the sea level caused by the gravitational pull of the moon and sun.

Waves: A wave is a disturbance that travels through space and matter, transferring energy from one place to another. Currents: Currents are the horizontal movement of water in the ocean, caused by the wind, temperature, and salinity gradients. Tides: Tides are the rise and fall of sea level caused by the gravitational pull of the Moon and the Sun on the oceans.

Tides are the periodic rise and fall of sea level caused by the gravitational pull of the moon and the sun. Waves are generated by wind, while currents are generated by the tides. Tides can be predicted up to seven days in advance using the moon's orbital period.
