What is a geological theory where the cooler surface of earth moves slowly over the hotter layer underneath?
The geological theory describing the movement of the cooler surface of the Earth over the hotter layer beneath is known as plate tectonics. This theory posits that the Earth's lithosphere is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below. The movement of these plates is driven by convection currents in the mantle caused by heat from the Earth's core. This process leads to various geological phenomena, including earthquakes, volcanic activity, and the formation of mountains.

True or false in the mantle hot material sink while cooler materials rise?
True. In the mantle, hotter, less dense material rises toward the Earth's surface, while cooler, denser material sinks. This process is part of mantle convection, which drives plate tectonics and influences geological activity. The continuous movement helps distribute heat from the Earth's interior to its surface.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
What is hotter surface of sun or core of earth?
Surface of the sun is hotter.
What luminosity of a star is related to its?
The luminosity of a star is related to its surface temperature and size. Hotter stars with larger surface areas tend to have higher luminosities, while cooler stars with smaller surface areas have lower luminosities.
Which layer is hotter then the surface of the sun?
The inner core is hotter then the sun's surface.
Is the sounthern cooler or hotter?
hotter
Are sun spots hotter or colder then the rest of the sun?
They are cooler than the average surface temperature of the Sun.

Why will the sun get hotter and hotter?
It wont, as the sun expands over time, the sun will become cooler and cooler.
Is the Sun cooler then Rigel?
No, Rigel is hotter than the Sun. Rigel is a blue supergiant star with a surface temperature that is much hotter than the Sun.
What color and surface temperature?
Stars come in various colors depending on their surface temperature. Hotter stars, like blue ones, have higher surface temperatures, while cooler stars, like red ones, have lower surface temperatures. The color and surface temperature of a star are generally related, with blue stars being hotter (around 10,000 K) and red stars being cooler (around 3,000 K).
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
Heat is transferred from?
