VS Science Test - Currents and Climates
What is the Coriolis Effect?
The effect of Earth's rotation on the direction of winds and currents.
What is a current?
Currents are a large stream of moving water that flows through the ocean.
What causes deep currents?
Different density,
What is La Nina?
A climate event that occurs when surface waters in the eastern Pacific are colder than normal.
What is El Nino?
An abnormal climate event that occurs every 2 to 7 years in the Pacific Ocean.
How do surface currents affect climate.
Because if the water is warm the climate is warm but if the water is cold the weather is cold.
How does the temperature of water affect its density?
Hot water is less dense and cold water is more dense.
How does the global ocean conveyor move?
It starts from the pacific then rises to the Indian Ocean.
Why is it helpful to a community to be able to predict an El Nino event?
So that they can prepare for the weather conditions.
What is the most powerful surface current?
The Gulf Stream.
What is Climate?
The pattern of temperature and precipitation typical of an area over a long period of time.
What causes surface currents?
The wind.
How are currents unalike waves?
They carry water from one place to another.
How do deep currents affect the ocean?
They mix water around the world and they carry the cold water to the equator.
