Why do Milankovitch cycles influence Earth’s climate?, They change Earth’s atmosphere, They alter the amount and distribution of solar energy received by Earth, They increase volcanic eruptions, They affect ocean salinity, The 100,000-year eccentricity cycle mainly affects:, Earth’s rotation speed, The shape of Earth’s orbit around the Sun, The tilt of Earth’s axis, The number of sunspots, Which statement best explains the link between orbital changes and ice ages?, Orbital changes affect solar radiation, influencing long-term climate patterns, Orbital changes directly create glaciers and ice caps, Orbital changes trigger volcanic eruptions, Orbital changes increase greenhouse gases, Why does increased sunspot activity lead to higher temperatures on Earth?, Sunspots block cold air and increases the temperature, The Earth moves closer to the Sun, The Sun emits more energy during periods of high sunspot activity, Solar flare exploded and emits radiation, What is the main role of sulphuric acid droplets in the atmosphere after a volcanic eruption?, They trap heat in the atmosphere, They absorb ocean water , They reflect incoming solar radiation, They increase oxygen levels, Why is volcanic cooling usually temporary?, Ash quickly settles out of the atmosphere, The Sun becomes hotter, Oceans absorb all heat, Earth’s orbit changes, Which combination would most likely result in global cooling?, High sunspot activity + low volcanic activity, Low sunspot activity + major volcanic eruption, High solar output + increased greenhouse gases, Stable orbit + high solar radiation.
