Topic 4.7: Solar Radiation and Earth’s Seasons
Learning Objective: ENG-2.A
Explain how the sun’s energy affects the Earth’s surface.
Essential Knowledge: ENG-2.A.1
Incoming solar radiation (insolation) is the Earth’s main source of energy and is dependent on season and latitude.
Essential Knowledge: ENG-2.A.2
The angle of the sun’s rays determines the intensity of the solar radiation. Due to the shape of the Earth, the latitude that is directly horizontal to the solar radiation receives the most intensity.
Essential Knowledge: ENG-2.A.3
The highest solar radiation per unit area is received at the equator and decreases toward the poles.
Essential Knowledge: ENG-2.A.4
The solar radiation received at a location on the Earth’s surface varies seasonally, with the most radiation received during the location’s longest summer day and the least on the shortest winter day.
Essential Knowledge: ENG-2.A.5
The tilt of Earth’s axis of rotation causes the Earth’s seasons and the number of hours of daylight in a particular location on the Earth’s surface.
