Convection Currents (Ocean and Wind)

Where does the sun heat up the Earths surface the most.

• The Equator

• The Atlantic Ocean

• The North Pole

• On Land

Answer explanation

The sun Heats up the Earth one the Equator because the radiation waves have less distance to travel through the atmosphere and it impacts a smaller section of the earths surface.

How does the Wind receive its Heat

• Through conduction from the Sun

• Through Conduction from the Earths surface

• Through Radiation from the Sun

• Through Radiation from the Earths surface

Answer explanation

The Sun heats up the Earths Surface through Radiation then the Earths surface heats up the the Wind through Conduction

What factors form Deep Currents?

• Salinity and Temperatures

• Wind and Surface Currents

• The Sun and the rotation of the Earth

• Conduction and Convection

Answer explanation

Salinity and Temperatures effect the formation of Deep Currents. The more Salt and Cooler waters the deeper the current.

Which water is more Dense?

• Hot Salt Water

• Room Temperature Water

• Cold Salt Water

• Warm Water

Answer explanation

The Colder or Saltier the water the more Dense it is because the particles are grouped together and sink.

Hot water is ____ Dense than Cold water

What is Continental Deflection?

• When Surface Currents get close to land the begin to bend around it.

• When Surface Currents bounce off of land.

• When the rotation or the Earth causes Surface Currents to Spin.

Answer explanation

Continental Deflection is when currents get too close to land that the bend to find another way around. Almost like they have a mind of their own!

The rotation of the Earth causes the winds to move from a straight line into a curved line, what is the Phenomena referred to as?

• The Coriolis effect

• The Axis effect

• The Cyclone effect

• The Rotation effect

Answer explanation

Just like a child spinning on a merry-go-round, when they throw the ball it travels in a curved path from their perspective.

Global Winds are formed within Convection Cells. These three Convection Cells originate from the equator and move towards the poles. These Convection cells change ever (blank) degrees?

• 20 degrees

• 30 degrees

• 40 degrees

• 50 degrees

Answer explanation

The Equator marks 0 degrees and the Poles mark 90 degrees. So you have Convection Cells change every 30 degrees. at 0, 30, and 60 degrees in the northern and southern hemisphere.

Global Winds are rising from (Blank) and sinking at (Blank)?

• Pacific Ocean / Atlantic Ocean

• Poles / Equator

• Equator / Poles

• Atlantic Ocean / Pacific Ocean

Answer explanation

Due to the Suns unequal heating of the Earth. The global winds rise at the Equator and Sink at the Poles.

High Pressure winds rise and Low Pressure winds sink

• True

• False

Answer explanation

High pressure winds are more dense because of the amount of particles grouped together, so they sink.

Low pressure winds are less dense because the particles are spread out so much, so they rise.
