This document defines and differentiates between ocean features such as gulfs, bays, and bights. It states that a gulf is a large body of salt water enclosed by land, often formed by tectonic plate movement. A bay is a smaller coastal body of water connecting to a larger body, and the Bay of Bengal is the largest. A bight is a recess in the coastline, such as the Great Australian Bight. The document also notes how geological processes like erosion and subduction can form gulfs and bays.

1. OCEAN FEATURES
GULF, BAY AND BIGHT
BY: ANUSHAY ABRAR

2. •Define ocean features.
•Differentiate between GULF , BAY and BIGHT.
•Geological occurrence of these features.

3. GULF
A portion of the ocean that penetrates (makes a hole) the land is known as gulf.
The term Gulf is traditionally used for large, carved, navigable bodies of salt water which
are enclosed by the coastline.
Strait is a narrow passage of water that connects the gulf with the ocean.
Gulf of Mexico, largest gulf of the world.

4. ❖ The Earth's tectonic plates may rift, or
break apart, creating a gulf.
❖ Gulf may also be formed when one
plate folds under another, this process
called Subduction.

5. • A large bay is usually called a gulf, sea, sound, or bight.
• A bay is a recessed, coastal body of water that directly connects to a larger main body of
water, such as an ocean, a lake, or another bay.
• The bay of Bengal is the largest bay in the world.
• The bight is a recess in a shore line.
• The great Australian bight is one of the largest bight in the world.
BAY and BIGHT

6. •When a stretch of coastline
is formed from different types of
rock, headlands and bays can form.
•Bands of soft rock such as clay and
sand are weaker therefore they can
be eroded quickly.
•This process forms bays.

10. QUESTIONS
• Distinguish between Gulf and Bight.
• Mention one way in which gulf and bay are formed.
• Analyze the process of Subduction.
• Define strait and identify its function.
