Science Convection Winds Ocean Currents

____________ occurs when heat is transferred into an object through motion or movement; an example would be boiling water.

• conduction
• convection
• radiation

The cycle that powers the ocean currents, weather, and tectonic plates it called

• conduction current
• radiation
• condition current
• convection current

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere
• the heat inside the earth heats the ocean and the ocean heats the air
• the sun cannot heat both the air and water, so one must heat the other
• the sun heats air and water more at the equator because it receives more direct sunlight

What is the Coriolis Effect and how does it effect global winds?

• Curving of winds due to rotation of earth curves wind counterclockwise in Northern Hemisphere and clockwise in the Southern Hemisphere
• Movement of ocean currents caused by earth rotation' counterclockwise in Northern Hemisphere and clockwise in Southern Hemisphere
• curve of global winds caused by global rotation clockwise in Northern Hemisphere and counterclockwise in Southern Hemisphere

As a result of the Coriolis effect in the northern hemisphere, winds are deflected:

• At a 45° angle from the original direction.
• At a 90° angle from the original direction.
• To the right of the original direction.
• To the left of the original direction.

• it is heavier
• it is more dense
• it contains Helium
