Practice and Revision - The Properties of Sea Water

Core concept

Salinity refers to the amount of dissolved salts in seawater, typically around 35 parts per thousand, though it varies by location.

How it works

Sea water temperature varies with depth and latitude, generally warmer near the surface and equator, colder in depths and polar regions.

Why it matters

Density of seawater is affected by both salinity and temperature - colder, saltier water is denser and sinks below warmer, less salty water.

Key detail

These properties influence ocean currents, marine ecosystems, and climate patterns, making them important for understanding ocean geography.
