The correct answer is true
The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides. The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth's oceans to form a tidal bulge.
Salutations!
The Earth is closer to the sun during summer in the Northern Hemisphere than it is during winter. True or False?
True. The Earth is closer to the sun because during the summer, the sun rays are directly hitting towards the Northern Hemisphere which makes it hot. During the winter, the sun rays are not directly hitting, thus, its cooler in winter than in the summer.
Hope I helped :D
No, because that is out of our range of sight and tools to search space.
