Properties of Water (Earth Systems)

Front

What is the main property of water that helps regulate Earth's temperature?

Back

Water has a high specific heat capacity, meaning it can absorb and store large amounts of heat without a significant change in temperature.

Front

What is the process by which warm water travels towards the poles?

Back

Warm water travels towards the poles through ocean currents, helping to redistribute heat across the planet.

Front

What is the average sea surface salinity?

Back

The average sea surface salinity is approximately 35 parts per thousand (ppt).

Front

What is sonar and how is it used in oceanography?

Back

Sonar (Sound Navigation and Ranging) uses acoustic signals and echoes to locate objects underwater and map the ocean floor.

Front

Which ocean is the largest on Earth?

Back

The Pacific Ocean is the largest ocean on Earth.

Front

How does the ocean help redistribute heat from the equator?

Back

The ocean carries thermal energy trapped in warm water to the poles, helping to balance global temperatures.

Front

What is downwelling in ocean currents?

Back

Downwelling is the process where surface water sinks due to increased density, often carrying oxygen-rich water to deeper layers.

Front

What role do ocean currents play in climate regulation?

Back

Ocean currents help transport warm and cold water around the globe, influencing climate patterns and weather.

Front

What is the significance of the equator in terms of solar radiation?

Back

The equator receives the most direct sunlight, leading to higher temperatures and influencing ocean currents.

Front

What is the difference between ocean and sea?

Back

An ocean is a larger body of saltwater that covers significant portions of the Earth's surface, while a sea is a smaller body of saltwater partially enclosed by land.
