Air-Sea Interdependancy
_______________________ are an interconnected system.
A change in the atm. affects the ocean & vice versa.
_________________ = gains & loses in heat on Earth.
Earth needs to ___________ as much heat back to space as it
____________ from the sun or the Earth’s climate will change.
______________ is not distributed ___________ on Earth.
Solar radiation is most intense between
23 ½˚N latitude (______________________) and
23 ½˚S latitude (______________________).
It is the most intense at the ______________.
There are two reasons for that:
1. Light rays are ______________________ toward the middle
of the Earth, so sunlight is more concentrated in that area.
2. Light has a shorter _____________________ through the
atmosphere at lower latitudes.
Air Pressure is the ____________ movement of air in a
convection current. It is how hard the air is pushing down on
Earth.
