In the context of Newton's Law of Gravity, what is tidal heating?
A
The increase in temperature of a planet's surface due to solar radiation.
B
The warming of a planet's atmosphere caused by greenhouse gases.
C
The process by which a planet's rotation slows down due to gravitational interactions with its moon.
D
The heating of a planet or moon's interior due to the gravitational forces exerted by another nearby celestial body.
Verified step by step guidance1
Tidal heating is a process that occurs due to the gravitational forces exerted by a nearby celestial body, such as a moon or another planet.
These gravitational forces create tidal bulges on the planet or moon, which are distortions in its shape.
As the celestial body orbits, these tidal bulges move, causing friction within the planet or moon's interior.
This friction generates heat, which can increase the temperature of the planet or moon's interior.
Tidal heating is significant in celestial bodies with eccentric orbits or those that are in close proximity to a massive body, as the gravitational forces are stronger and more variable.
