Seas

Seas are large bodies of saltwater that are smaller than oceans and are partially enclosed by land.

Formation of Seas

Seas are formed through a variety of processes, including the sinking of land due to tectonic plate movements, volcanic activity, and the rise in sea level due to melting glaciers.

Characteristics of Seas

• Seas are interconnected with the ocean and are often located where the land and ocean meet.
• They are shallower than oceans and may have varying salinity levels due to freshwater input from rivers.
• Seas support a diverse range of marine life and are important for fishing and transportation.

Types of Seas

There are different types of seas, including marginal seas, mediterranean seas, and enclosed or semi-enclosed seas. Each type has its unique characteristics and significance.

Human Impact on Seas

Human activities such as pollution, overfishing, and coastal development have significantly impacted the health of seas and their ecosystems. It's important to understand the importance of conservation and sustainable practices to protect these vital bodies of water.
