Neptune an 1. Sun Mercury Jupiter Uranus In approvimately Sbillion years, the Sun will start to do. As it starts to die.the Sun will expand becoming much larger. The diagram shows the predicted changes in the habitable some of the Sun as it changes. Why will the Earth no longer be in the habitable zone of the Sun? Select TWO correct answers Gravity will become stronger and water will become too heavy. The tides will become too large for organisms to survive. The four inner planets will become too hot to support life. The Sun's gravity will move Saturn's rings into the Earth's orbit. Water will no longer exist in liquid form on Earth.

Answer 1

The four inner planets will become too hot to support life, Water will no longer exist in liquid form on Earth.

Answer 2

The habitable zone of a star is defined as the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. As the Sun ages and expands, it will become hotter and more luminous, which will affect the habitable zone. Option (1) is incorrect because gravity does not directly affect the state of water on a planet. The weight of water is determined by the planet's gravity, not the Sun's. Option (2) is also incorrect. While it's true that the Sun's gravity affects tides on Earth, the Sun becoming a red giant will not directly cause tides to become too large for organisms to survive. Option (3) is correct. As the Sun expands and becomes hotter, it will indeed make the four inner planets, including Earth, too hot to support life as we know it. Option (4) is incorrect. The Sun's gravity will not move Saturn's rings into Earth's orbit. The changes in the Sun's gravity as it expands will not be significant enough to cause such a drastic shift in the solar system's structure. Option (5) is correct. As the Sun expands and heats up, the increased heat will cause water on Earth to evaporate and eventually escape into space, making it impossible for liquid water to exist on the surface. #
