Sentence under Planetary Science webinar Part 4

Planetary Science 2014 – Part 4 The Tiger Stripes in the southern region of Enceladus are produced by the gravity from Saturn. The resulting tidal forces cause large areas of the surface to push together or pull apart or slide along each other. This causes the material beneath the surface to heat due to the tidal stresses, and the resulting flexing on the moon allows geysers to form and eject materials from beneath the surface of Enceladus. The orbital position graph shows the resulting change in elevation due to the faultparallel and vertical displacements. Look at different types of diagrams and graphs and charts that result in the movement of water. Do not study.

Just one or two types of charts or illustrations as several different types may be used in the interpretive tasks. Iapetus is the third largest satellite of Saturn and has both dark areas and bright areas. It is locked in synchronous rotation with Saturn and orbits very slowly. It is surrounded by other moons of Saturn. It is thought that the dust and debris from the other moons settle onto the surface of Iapetus in the equatorial regions. When radiation reaches this part of the surface, the ice sublimates leaving behind the dust. The ices then condense towards the polar regions. The dark regions keep getting darker as more and more dust accumulates, and the light regions.

Keep getting brighter as more and more ices condense in those area. Iapetus also has a bizarre ridge that circles the moon which I will talk about on the next slide. This is part of the transitional zone between the bright ice regions and the dark dusty regions. Study this zone to understand where materials are sublimating and where they are condensing. This is the ridge that circles Iapetus – called The Wall. Iapetus used to rotate faster and had a more oblate shape with the diameter wider in the equatorial region, similar to the shape of Earth. One possibility is that The Wall is the result of surface material forming as the moon rotated slower and slower.

One other possibility is that Iapetus used to have its own ring and the ring material collapsed onto the surface of the moon. Titan is the largest moon of Saturn and is known for being the only moon in the Solar System with a thick atmosphere. The atmosphere is composed of hydrocarbons. This graphic illustrates the possible underlying structure of Titan, showing a global subsurface hydrocarbon ocean sandwiched between a decoupled icy shell and high pressure ice above a hydrous silicate core. This is an artist illustration of the surface and atmosphere of Titan. It is thought that on the surface methane exists at its triple point. On Earth water exists at its triple.

Point – all three phases of liquid, gas, and solid. On Titan methane displays the same property, so Titan has methane clouds, methane rain, methane lakes, and methane ice and oceans. We know what the surface of Titan actually looks like as the Cassini mission deployed the Huygens probe into the atmosphere and captured images until it stopped functioning. This is an actual raw image of the Titan surface taken by the Huygens probe and it shows the remnants of channel edges and drainage channels and patterns. These images show that large amounts of liquids have moved across the surface of Titan in the past. This is an elevation map of Titan assembled from several images captured by the probe.

It shows the topography and elevation of the moon. Make sure to research and put together images similar to this for all of the features and objects that are listed in the event description. An archive of different types of graphs, charts and data are important resources for this event.
