Q: What are some factors that will affect the future of the Earth?
A: Many things will affect the future of the Earth including increases in the brightness of the Sun, loss of heat energy from the Earth's core, and changes in the planet's orbit caused by other things in the Solar System.
Q: What is the Milankovitch theory?
A: The Milankovitch theory says that the Earth will continue to go into glaciation cycles because of the planet's difference in orbit from a perfect circle, the axis of the planet tilting, and pushing of the Earth's orbit.
Q: How might plate tectonics affect the future of the Earth?
A: Plate tectonics may create a supercontinent within 250 million–350 million years as part of the supercontinent cycle.
Q: What might happen to the Earth's axis in the future?
A: Some time in the next 1.5 billion–4.5 billion years, the axis's tilt may begin to change into bad versions, with changes in the axis's tilt of up to 90°.
Q: How might the Sun affect the future of the Earth?
A: One billion to two billion years in the future, the increase in solar radiation caused by the helium build-up at the core of the Sun will result in the loss of the oceans and the cessation of continental drift. Four billion years from now, the increase in the Earth's surface temperature will cause a bad greenhouse effect.
Q: What is the most likely fate of the planet?
A: The most likely fate of the planet is being destroyed by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded to cross the planet's orbit.
Q: Will there be any life left on the Earth in 4 billion years?
A: By that point, most if not all the life on the Earth will be gone.
