Ocean Currents 1
How does salt affect the density of water
it makes water more dense
What happens when air is heated?
it rises
What is a surface current?
Currents driven by changes in wind
What part of the Earth receives the most direct sunlight?
Do objects in saltwater sink of float?
What happens to cool air/water when mixed with warmer air/water?
it sinks
What is a density current?
Currents driven by changes in density
the poles
What two things affect the density of water?
temperature and salinity
How does temperature change the density of water?
density decreases as temperature increases
density increases as temperature decreases
What are ocean currents?
How does the uneven heating of Earth affect weather patterns?
it helps to create wind and ocean currents
What is the driving force for ocean currents?
what is the terms for the direction of water flowing to the right in the Northern Hemisphere and to the left in the Southern Hemisphere?
The Coriolis Effect
The uneven heating of Earth causes what two things to occur?
wind
ocean currents
What causes the uneven heating of Earth's surface?
the tilt of the Earth's axis
How does the uneven heating of Earth's surface contribute to the formation of wind?
it creates a temperature difference that leads to the movement of air masses
