The density and temperature increase with depth, and the atmosphere gradually liquefies at a depth of a few thousand kilometers. Below a depth of 20,000 km, the hydrogen behaves like a liquid metal. At the center of the planet lies a large rocky core, somewhat terrestrial in composition.
1 Ιαν 2020 · Below the tropopause, temperatures increase with increasing depth as the most efficient means of energy transport is convection and the atmospheric temperature profile is roughly adiabatic. This portion of the atmosphere is heated from below.
11 Απρ 2022 · Describe the cloud formation and atmospheric structure of the gas giants. Characterize the giant planets’ wind and weather patterns. Understand the scale and longevity of storms on the giant planets. The atmospheres of the jovian planets are the parts we can observe or measure directly.
Why do the jovian planets have rings? • They formed from dust created in impacts on moons orbiting those planets. © 2017 Pearson Education, Inc. How do we know?
The order in which they condense with increasing depth varies from planet to planet. The altitude at which these condense will increase with increasing saturation vapor pressure, decrease with increasing abundance, and increase with increasing temperature.
All the jovian planets have ring systems. Rings are made of many tiny orbiting particles, rocks, and ice balls. Most rings are inside the Roche limit of the host planet. Rings flatten and spread due to collisions, but embedded moonlets and larger exterior moons can keep ring segments in place.
1 Σεπ 2010 · Its main ring is located at 1.71R J ≤ r ≤ 1.81R J (the planet's radius R J ≃ 71,398 km) with an optical depth τ ≃ 10 −5. The main ring consists of ‘large bodies’ in the centimeter to meter size range [Showalter et al., 2007] and also a large population of small dust particles in the 0.1 ≤ a ≤ 100 μm size range. The small ...
