Hydrosphere Ocean Currents Quiz

Ocean Features and Movements

• The most important feature of the ocean is its ability to regulate the Earth's climate and provide half of the oxygen we breathe.

Ocean Water Movements

• Deep water moves towards the equatorial region as an undercurrent.

Earth's Surface Coverage

• About 71% of the Earth's surface is occupied by seas, oceans, lakes, and rivers.

Ocean Currents

• The vertical movement of ocean water is known as upwelling.
• The main feature of ocean currents is that they are driven by winds, tides, and thermohaline circulation.
• Warm and light ocean water moving towards the polar region characterizes the surface currents.

Ocean Coverage

• About 97% of the Earth's surface water is occupied by oceans.

Ocean Currents and Movements

• The horizontal movement of ocean water in a definite direction and regular pattern is called a current.
• Deep water moves towards the equatorial region as an undercurrent.
• Ocean water movements can be classified into surface currents and undercurrents based on their direction and type.
