Convection currents are formed due to the density difference between layers of fluid. The heated layers rise up because their density is less than that of the colder layers. Hope this helps!
Answer:
9. The Sun's Gravity
10. The core is the densest layer
The Earth orbits the sun constantly, continuously, and all the time. " 24/7/365 "
From the sun's point of view, it takes the Earth roughly 365 and 1/4 days
to make the complete trip, all the way around one time. That's the length
of time that we call "one year".
When you talk about orbiting in one month, you're thinking of the moon
orbiting the Earth. THAT length of time is about 27.32 days.
