2.5.1 The Solar System

• What are the two main groups of planets in the Solar System?

  Terrestrial and gas giant
• Jupiter is the largest planet in the Solar System and has a giant storm called the Great Red Spot
• Comets are icy bodies with highly elliptical orbits
• What are the two main categories of planets based on their composition?

  Terrestrial and gas giants
• Match the component of the Solar System with its description:

  Sun ↔️ Central star providing light and heat

  Planets ↔️ Large bodies orbiting the Sun

  Asteroids ↔️ Rocky fragments in the asteroid belt

  Comets ↔️ Icy bodies with elliptical orbits
• Which planets are classified as gas giants?

  Jupiter, Saturn, Uranus, Neptune
• Arrange the terrestrial planets in order of their distance from the Sun.

  1️⃣ Mercury

  2️⃣ Venus

  3️⃣ Earth

  4️⃣ Mars
• Asteroids are rocky fragments orbiting mainly between Mars and Jupiter, forming the asteroid belt
• Without the Sun's gravity, the Solar System would fall apart, and objects would drift into space
• What is Earth's only natural satellite?

  The Moon
• What is the hottest layer of the Sun where nuclear fusion occurs?

  Core
• What are the two main groups of planets in the Solar System?

  Terrestrial and Gas Giant
• What are terrestrial planets made of?

  Rock and metal
• Earth is the only known planet to support life
• Jupiter has a giant storm called the Great Red Spot.


  True
• Neptune is the farthest planet from the Sun.

  True
• Arrange the gas giant planets in order of their distance from the Sun.

  1️⃣ Jupiter

  2️⃣ Saturn

  3️⃣ Uranus

  4️⃣ Neptune
• Where is the asteroid belt located?

  Mars and Jupiter
• What maintains the structure and arrangement of the Solar System?

  Gravity
• The Solar System is held together by the Sun's gravity
• The hottest part of the Sun, where nuclear fusion occurs, is the core
• Sunspots are found on the photosphere.


  True
• Which planet is known for its bluish-green color and unique tilt?

  Uranus
• What is a dwarf planet?

  A celestial body with spherical shape, but has not cleared its orbit
• What fundamental force holds the Solar System together?

  Gravity
• Gravity is the force that keeps all objects within the Solar System bound together.


  True
• Match the Sun's layer with its description:

  Core ↔️ Hottest part where nuclear fusion occurs

  Radiative Zone ↔️ Transfers energy from the core

  Convective Zone ↔️ Circulates energy through convection
• Match the planet with its description:

  Mars ↔️ Reddish color, evidence of past water

  Saturn ↔️ Prominent ring system, low density

  Neptune ↔️ Coldest planet, dark blue color
• Why is Venus so hot?

  Dense atmosphere
• Uranus is known for its bluish-green color and being tilted on its side
• Arrange the terrestrial planets in order of their distance from the Sun.

  1️⃣ Mercury

  2️⃣ Venus

  3️⃣ Earth

  4️⃣ Mars
• Why are terrestrial planets small and rocky?

  Sun's gravity
• Comets have highly elliptical orbits and release gas and dust to form a visible tail
• Saturn's moon Titan is the second-largest moon in the Solar System.


  True
• What is the Solar System defined as?

  A gravitationally bound system
• What force keeps the components of the Solar System bound together?

  Gravity
• Mercury is the closest planet to the Sun and has a heavily cratered surface.


  True
• What is the Great Red Spot on Jupiter?

  A giant storm
• Which planet is known for its prominent ring system?

  Saturn
• The coldest planet in the Solar System is Neptune
