How does the Earth lose its heat? NASA explained that Earth’s hot core heats the mantle, which then conducts the heat to the lithosphere, the outermost solid layer of rock. The heat is subsequently released into space, cooling the top of the curtain. This circulation of the mantle, called mantle convection, is responsible for driving tectonic processes at the surface and keeping the plates in motion. But the mechanism of Venus’ heat flow has been a mystery until now. The absence of tectonic plates on Venus has resulted in persistent questions in planetary science about how the planet loses its heat and what processes shape its surface.
A recent study analyzed the archive. NASA The data also suggest that Venus may be releasing heat due to geological activity in regions known as coronae, similar to early tectonic activity on Earth. The research uses three decades of data from NASA’s Magellan mission with a new perspective. Here’s what the study says about Venus.
How Venus’s Heat Transfer Mechanism Works
Using observations made by the Magellan spacecraft in the early 1990s, geologic features surrounding the corona Zahrathe researchers found that “the corona occurs where the planet’s lithosphere is thinnest and most active.”
Until now, scientists believed that the lithosphere Zahra is solid and thick. NASA further explained that just as a thin mantle radiates more body heat than a thick mantle, a thin lithosphere would allow more heat to escape from the planet’s interior through buoyant plumes of molten rock. Is. In general, elevated heat flow results in increased subsurface volcanic activity. Therefore, the corona potentially exposes areas where active geology is currently affecting the surface of Venus.
According to the new research, the lithosphere surrounding each corona is on average about 7 miles (11 km) thick, much thinner than previously estimated. These regions exhibit higher projected heat fluxes than regions. Earthwhich indicates that the corona is actively experiencing geological processes.
Also, NASA said in a blog that “the youthful appearance of Venus’ surface is due to volcanic activity, which is resurging regionally today.” Additionally, this recent discovery of enhanced heat flow in coronal regions supports the idea that Earth’s lithosphere may have exhibited a comparable state in the past, NASA said.
