Why does Earth experience day and night?, Earth rotates on its axis., Which type of light is mostly absorbed by the ozone layer?, Ultraviolet (UV) light., How does the Sun make life possible?, It provides energy for photosynthesis, What happens when the Sun, Moon, and Earth align?, Higher high tides and lower low tides (spring tid, Where do new solar systems form?, In clouds of gas and dust called nebulae, Which sequence describes solar system formation?, Rotating cloud collapses → Flattened →Fusion-> planets form from accretion, What is the main source of electromagnetic energy on Earth?, The Sun, How do terrestrial and Jovian planets differ?, Terrestrial: rocky, dense, few moons, inner system. Jovian: gas/ice, low density, many moons, outer system, What changes from winter to summer?, Sunlight becomes more intense in summer, How does photosynthesis affect Earth’s energy budget?, It converts solar energy into chemical energy, What causes winds and ocean currents?, Uneven heating from incoming solar radiation, Which type of light is mostly absorbed by the ozone layer?, Ultraviolet (UV) light, How does the Sun release energy into space?, Fusion in the core produces electromagnetic radiation, How does wavelength relate to energy?, Shorter wavelengths carry more energy, Where does nuclear fusion occur in the Sun?, In the core, How does the Sun produce energy?, Hydrogen atoms fuse into helium, releasing energy, Arrange EM waves from lowest to highest energy:, Radio → Microwave → Infrared → Visible → UV → X‑ray → Gamma, Order the Sun’s layers from innermost to outermost:, Core → Radiative Zone → Convective Zone, What process formed the Sun?, The solar nebula collapsed into a dense, hot core, How did the solar system form according to the nebular theory?, A collapsing, spinning cloud flattened into a disk with the Sun forming at the center, What do equal shaded areas in a planet’s orbit represent?, Equal time intervals — planets sweep equal areas in equal times, How does Earth’s tilt create seasons?, It changes the angle and intensity of sunlight each hemisphere receives, How do moon phases influence tides?, New and full moons create spring tides; quarter moons create neap tides, How does the Earth–Moon barycenter affect Earth’s motion?, Earth wobbles slightly because the barycenter is inside Earth but not at its center, Why do different latitudes receive different amounts of daylight?, The equator gets consistent sunlight; the poles experience extreme seasonal changes
