4.7-4.8 Flashcards
4.7-4.8
Total Solar intensity
Max amount of energy delivered to earth from the sun
4.7-4.8
Insolation
The amount of solar radiation reaching a specific area
4.7-4.8
Solar intensity depends on
Angle and Atmosphere
how directly rays strike earth’s surface
The amount of ________ sun’s rays pass through
4.7-4.8
Tilt of earth causes variations in
Angle of Insolation (which changes intensity)
Length of day
Season
4.7-4.8
What are the Equinoxs
- in Fall and Spring
- When there are 12 hrs in day
Normally in March and September
4.7-4.8
What are Solstice
One hemisphere is tilted more to the sun
Normally in June and December
4.7-4.8
What is the Albedo Effect
the proportion of light that is reflected by a surface
High albedo is in whiter regions (Artic)
Low albedo is in darker regions (cities)
4.7-4.8
What is Insolation based on?
Earth’s shape, tilt, & angle of rays.
What does rotation cause?
Day and Night
4.7-4.8
What does a revolution cause
Season
4.7-4.8
How does Climate and Geography effect insolation
Climate: Latitude reviece less insolation + (30 degrees least presures)
Geography: Mountain disrupt air low + produce rain shadow effect
Oceans: Moderate temp + add moisture to air
