      False
    • Match the season with its corresponding key event:
      Spring ↔️ Spring Equinox
      Summer ↔️ Summer Solstice
      Autumn ↔️ Autumn Equinox
      Winter ↔️ Winter Solstice
    • The solar constant, denoted by S, quantifies the intensity of solar radiation.
    • Which type of solar radiation has the lowest energy level?
      Infrared radiation
    • Infrared radiation warms the Earth's surface and atmosphere.
    • Why does solar radiation vary at different latitudes?
      Angle of incidence
    • Match the latitude region with its angle of incidence:
      Equatorial ↔️ Direct
      Polar ↔️ Shallow
      Mid-Latitudes ↔️ Moderate
    • Earth's axial tilt is the angle of 23.5° between its rotational axis and its orbital plane.
    • What happens to solar radiation when the Northern Hemisphere is tilted towards the Sun?
      Summer
    • What is the angle of Earth's axial tilt?
      23.5°23.5°
    • When the Northern Hemisphere is tilted towards the Sun, it receives high levels of solar radiation
    • Match the hemisphere with its season when tilted towards the Sun:
      Northern Hemisphere ↔️ Summer
      Southern Hemisphere ↔️ Winter
    • Order the seasons in the Northern Hemisphere based on Earth's orbit around the Sun:
      1️⃣ Spring
      2️⃣ Summer
      3️⃣ Autumn
      4️⃣ Winter
    • The Spring Equinox occurs on March
    • What occurs during the Summer Solstice in the Northern Hemisphere?
      Longest day
    • Match the event with its description:
      Solstice ↔️ Maximal tilt towards Sun
      Equinox ↔️ Sun crosses celestial equator
    • The Winter Solstice marks the shortest day of the year in the Southern Hemisphere.
      False
    • What are the three components of solar radiation?
      Visible light, infrared, UV
    • Visible light has a wavelength range of 380750380 - 750 nm and drives photosynthesis
    • Infrared radiation warms the Earth's surface and atmosphere.
    • Match the type of solar radiation with its key impact:
      Visible light ↔️ Enables vision
      Infrared radiation ↔️ Heats Earth
      Ultraviolet (UV) radiation ↔️ Causes sunburns
    • Why does solar radiation vary at different latitudes?
      Angle of incidence
    • At the equator, sunlight strikes at a direct angle, resulting in higher temperatures
    • Earth's seasons are primarily affected by its axial tilt and revolution around the Sun.
    • Order the seasons in the Northern Hemisphere from warmest to coldest:
      1️⃣ Summer
      2️⃣ Spring
      3️⃣ Autumn
      4️⃣ Winter
    • What is the approximate inclination of Earth's axial tilt?
      23.5°23.5°
    • Earth completes one orbit around the Sun every 365.25 days.
    • The Northern Hemisphere experiences spring when tilted towards the Sun.
    • Match the hemisphere with its key seasonal event:
      Northern Hemisphere ↔️ Summer Solstice
      Southern Hemisphere ↔️ Winter Solstice
    • What type of path does the Earth follow in its orbit around the Sun?
      Elliptical path
    • The Earth completes one revolution around the Sun approximately every 365.25 days.
    • When the Northern Hemisphere is tilted towards the Sun, it experiences spring and summer.
    • What seasons does the Southern Hemisphere experience when the Northern Hemisphere has spring and summer?
      Autumn and winter
    • Solstices and equinoxes are astronomical events marking the change of seasons.
