Reason For the Seasons

winter The Northern Hemisphere of Earth is tilted away from the Sun. summer The Northern Hemisphere of the Earth is tilted in toward the Sun. autumn (fall) Earth is not tilted toward or away from the Sun. Starts on September 21st. spring Earth is not tilted toward or away from the Sun. Starts on March 21st. season short period of climate change in an area caused by the tilt of Earth's axis as Earth revolves around the sun. (winter, summer, autumn, spring) equinox when the sun's direct light is closest to the equator causing 12 hour of daylight in both hemispheres Draw a picture of one of the seasons in terms of the Sun - Earth System. Don't forget to include which season you have drawn, the axial tilt, and the Equator. As the length of the daylight period decreases, the heating effect on the Earth _?_. increases decreases remains the same As the Sun's angle of incoming solar radiation decreases, the heating effect on the Earth _?_. increases decreases remains the same Which diagram best represents the tilt of Earth’s axis in relation to the Sun in December in the Southern Hemisphere? 1 2 3 4 Which diagram best represents the tilt of Earth’s axis in relation to the Sun in December in the Northern Hemisphere? 1 2 3 4 Which diagram best represents the tilt of Earth’s axis in relation to the Sun in during an equinox? 1 2 3 4 On which date does North America usually experience the longest period of daylight? March 21st June 21st September 21st December 21st The seasons are caused by _?_. the changing distance between the Earth and Sun the changing distance between the Moon and Sun the 23.5 degree tilt in the rotation axis of the Earth the changing temperature of the Sun throughout the year What happens at an equinox? The Moon rotates on its axis in the same time it takes to revolve around Earth. The Sun is directly above Earth's equator; daylight hours equal nighttime hours. The Sun is at its greatest distance north or south of the equator. Earth's orbit reverses. Describe how the length of daylight changes from the Equator to the North Pole on the day shown. decreases increases remains the same What season came before this one in the Northern Hemisphere? winter spring summer autumn (fall) Near which of the 5 major lines of latitude is the Sun’s most direct rays on the day shown. the Equator Tropic of Cancer Tropic of Capricorn the Antarctic Circle the Artic Circle What season is going to occur next in the Southern Hemisphere in the diagram? winter spring summer autumn (fall)
