Oceanography: Exploring the Oceans

The Wonders of the Ocean

Oceanography is the study of Earth's oceans—their chemistry, movement, creatures, and impact on the planet. Oceans cover more than 70% of Earth's surface and are essential for life.

Ocean Layers

  • Surface Zone: Warm and well-lit.
  • Thermocline: Rapid temperature changes.
  • Deep Zone: Cold and dark.

Ocean Currents

Oceans are always moving! Currents carry warm and cold water around the globe, affecting weather and climate.

Why Oceans Matter

Oceans provide food, regulate climate, and support millions of species. They also play a role in the water cycle and carbon storage.

Examples

  • Studying coral reefs to learn about marine biodiversity.

  • Tracking ocean currents that influence weather patterns.

In a Nutshell

Oceanography explores the physical, chemical, and biological features of Earth's oceans.

Key Terms

Current
A continuous movement of seawater.
Thermocline
A layer in the ocean where temperature changes quickly with depth.
Marine
Related to the ocean.
