Solar System Models
Which model places the Sun at the center with planets orbiting it?
👉 Heliocentric model
What causes Earth’s seasons?
👉 The tilt of Earth’s axis
What did Hubble’s telescope prove about the universe?
👉 There are galaxies beyond the Milky Way
What causes changes in daylight hours in places like Atlanta and Anchorage?
👉
Earth’s tilt on its axis
Which scientist improved the telescope and observed Jupiter’s moons?
👉 Galileo
Which scientist proposed the heliocentric model of the solar system?
👉 Copernicus
If Earth’s axis were not tilted, how would the seasons change?
👉 There would be no seasons—both hemispheres would get the same sunlight year-round
What does the Big Bang Theory state?
👉 Was the universe small, exploded and is still growing
Which city has the greatest increase in daylight hours from winter to spring?
a. Boston
b. Anchorage
c. Tampa
👉
Anchorage
Who discovered that galaxies are moving apart, supporting the Big Bang?
👉 Edwin Hubble
What change must be made to a model of the solar system to make it heliocentric?
👉 Place the Sun at the center
Why is North America in summer on June 21st?
👉 Earth’s axis is tilted toward the Sun
Where is the Sun located in the Milky Way Galaxy?
👉 A medium-sized star, closer to the edge than the center
What happens to daylight hours in the Northern Hemisphere from winter to summer?
👉 They increase
Which scientist proposed the geocentric model with Earth at the center?
👉 Ptolemy
Who explained that planets orbit the Sun in elliptical paths?
👉 Kepler
How does Earth’s tilt affect sunlight at the equator?
👉 The tilt has little effect; daylight and temperature stay nearly the same all year
How is our solar system related to the universe?
👉
One of many systems in the Milky Way, which is one of millions of galaxies
What pattern do daylight hours in Atlanta show through the year?
👉 Longer in summer, shorter in winter
👉 Ptolemy
Who discovered cosmic background radiation, also supporting the Big Bang?
👉 Arno Penzias
Which is the correct order from smallest to largest: planet, solar system, galaxy, universe?
👉 Planet → Solar System → Galaxy → Universe
Which direction does Atlanta face during summer vs. winter?
👉 Toward the Sun in summer, away from the Sun in winter
Which order correctly shows our location in the universe of the following: galaxy, universe, solar system
👉
Solar System → Milky Way Galaxy → Universe
When does Anchorage get the least daylight?
👉 Winter
Which three scientists helped shape the modern solar system model?
👉 Copernicus, Kepler, and Galileo
