Properties of Ocean Water

1. Properties of Ocean Water

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.

Ocean Circulation: Patterns & Effect on Climate

2. Ocean Circulation: Patterns & Effect on Climate

The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.

Characteristics of Shorelines & Beaches

3. Characteristics of Shorelines & Beaches

Shorelines and beaches are constantly changing due to forces, such as waves, winds and currents. Learn about characteristics of shorelines, including headlands, bays, beach berms, sand dunes, spits, tombolos, barrier islands and lagoons.

Waves: Types, Features & Effect on Erosion

4. Waves: Types, Features & Effect on Erosion

There are different types of ocean waves, including wind waves, tsunamis and tidal waves. Learn the features of waves and how their erosive effect creates the unique features found on the shoreline.

Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

5. Contributing Factors of Longshore Transport: Beach Drift & Longshore Current

The longshore transport is the process responsible for the movement of sand and sediment along the coastline. Sand and other particles are transported with the help of the longshore current and beach drift. Learn how these factors shape shorelines.

What Are Tides? - Causes & Effects

6. What Are Tides? - Causes & Effects

Tides rise and fall under the influence of the gravitational pull of the moon and sun. Learn about different tides, why they are predictable and their effects on coastal regions of the world.

The Causes & Effects of a Tsunami

7. The Causes & Effects of a Tsunami

A tsunami is a powerful series of waves that result due to an abrupt disturbance, such as an earthquake. Learn how tsunamis form and grow and discover the devastating effects they can have on people and the environment.
