Study Notes
Ocean Basins
- A low spot on Earth's surface, surrounded by high land, that fills with water over millions of years.
- Five major oceans (largest to smallest): Pacific, Atlantic, Indian, Southern, Arctic.
Formation of Oceans
- Volcanic Action: Water vapor released from volcanic materials cooled, condensed, and flowed into ocean basins.
- Plate Tectonics: Pangea, a supercontinent, broke apart, separating continents and forming the oceans we have today.
- Erosion: The breakdown and movement of rock material constantly shapes ocean basins.
- Glaciation: Glaciers erode land, contributing to drainage systems and shaping landscapes during ice ages.
Ocean Floor Features
- Continental Shelf: The submerged part of a continent close to the shore, gradually sloping away. The Grand Banks off Newfoundland is a notable example.
- Continental Slope: Steeply sloping area at the edge of the continental shelf, leading to the abyssal plain.
- Abyssal Plain: Flat areas on the deep ocean floor.
- Ocean Ridges: Long undersea mountain ranges formed by magma rising from Earth's core. The Mid-Atlantic Ridge is the largest.
- Ocean Trench: Deep depressions in the ocean floor formed when tectonic plates collide. The Mariana Trench is the deepest.
Exploring the Ocean Floor
- Sonar: Uses sound waves to map the ocean floor and determine depth.
- Satellites: Survey large areas of the ocean quickly, gathering data in all types of weather.
- Core Sampling: Taking samples of the ocean floor to study its layers and composition.
- Underwater Photography/Videography: Using cameras to capture pictures and videos of the deep ocean.
- Deep Sea Submersibles: Small, strong vehicles that explore the deepest parts of the ocean providing detailed information.
- Diving: Physically going into the water to explore, with limited depth due to pressure.
Ocean Currents
- Current: Large amounts of ocean water moving in a specific direction. Influenced by wind (surface currents) and temperature/density (deep water currents).
- Local Currents:
- Labrador Current: Cold water current.
- Gulf Stream: Warm water current affecting Newfoundland's climate due to interaction with Labrador current.
Ocean Waves
- Waves: Large ripples in the ocean caused by wind.
- Types:
- Swell: Smooth waves in calm weather.
- Breaker: Waves that collapse near the shore.
- Tsunami: Large waves caused by earthquakes, landslides, or volcanic eruptions.
Wave Interactions with Shorelines
- Wave Erosion: Rocks are worn down.
- Sediment Deposition: Material is carried and dropped.
- Tides: Affect shorelines by interacting with wave energy and currents.
- Shoreline Features: Rocky beaches, sandy beaches, headlands, and bays created and shaped by waves.
Ocean Tides
- Tides: Daily rise and fall of ocean water.
- Tidal Range: Difference in water level between high and low tides.
- Spring Tides: High tide/low tide range due to Sun, Earth, and Moon aligning.
- Neap Tides: Smaller tidal range due to Sun and Moon being at right angles.
