How does the position of the sun change during the day and year?

When is the sun at the highest altitude in the sky during the day? Solar noon- highest point in the sky during the day usually occurring around 12pm.

How does your shadow change throughout the day? The longest shadows occur when the sun is at its lowest angles [sunrise and sunset]. The shortest shadow occurs at solar noon. All shadows north of 23 1/2 north are pointing North because the sun is always in the south sky.

When is the sun at the highest altitude in the sky during the year? In the N.H. June 21 st and the lowest altitude on Dec 21 st. In the S.H. Dec 21 st and the lowest altitude on June 21 st.

How does your shadow change at solar noon during the year? Your shadow is the shortest on June 21 st and the longest on December 21 st. Your shadow always points northward.

At which latitude would the duration of insolation be greatest on December 21? 23½º South 0º 10º North 23½º North

Letter A through D in the diagram represent four processes that can occur when water changes phase. Which process requires the addition of 2260 joules per gram? A B C D

Which conclusion is best supported by the diagram? All types of electromagnetic energy reach Earth’s surface. Gamma rays and x rays make up the greatest amount of electromagnetic energy reaching Earth’s surface. Visible light makes up the greatest amount of electromagnetic energy reaching Earth’s surface. Ultraviolet and infrared radiation make up the greatest amount of electromagnetic energy reaching Earth’s surface.

Which part of the Sun’s electromagnetic spectrum has the longest wavelength? radio wave radiation infrared radiation visible light radiation x-ray radiation

Which graph best represents the relationship between the angle of insolation and the intensity of insolation?

Tropical rain forests remove carbon dioxide gas from Earth's atmosphere. The destruction of the rainforests could affect Earth's overall average temperature because: more of Earth's reradiation would be absorbed by the atmosphere more sunlight would be reflected back to space by Earth's atmosphere more visible light would be absorbed by Earth's atmosphere more ultraviolet light would be transmitted through Earth's atmosphere

Which graph below best represents the intensity of insolation and the surface temperature for a location at the Equator?

Which gases in the Earth's atmosphere are the best absorbers of infrared radiation? carbon dioxide and water vapor carbon dioxide and oxygen nitrogen and oxygen nitrogen and water vapor

Most of the energy in the Earth’s atmosphere comes from: the rotation and revolution of the Earth the rotation of the Earth and wind from the Earth radioactive decay of elements and radiation from the Earth radiation from the Earth and insolation from the Sun

At which location is the angle of insolation greatest at solar noon?
