Question
In the slides we saw evidence of past liquid water on Mars' surface, including (a) evaporate minerals and hematite nodules ("blueberries"), (b) ancient valley networks and outflow channels, (c) ripple-marked sedimentary rocks, (d) b and c, (e) all of these Small circular volcanic features on Venus with very steep sides, probably formed from sticky (viscous) lava, are called: (a) pancake domes, (b) splash craters, (c) shield volcanoes, (d) sinuous rilles (lava channels), (e) terraces Folded mountains occur over some areas of Venus. These appear to be due to crumpling of the crust, in response to: (a) upwelling mantle plumes (hot spots), (b) subsiding mantle plumes (cool or cold spots), (e) shield volcano formation, (d) planetary expansion, (e) a and d It is hypothesized that Venus has been resurfaced within the last 500 million years, probably through massive lava flows. What evidence suggests this? (a) a uniform distribution of impact, craters, (b) mountains on Venus, (c) Venus has no impact craters, (d) sedimentary rocks, (e) c and d Which spacecraft landed on Mars' surface? (a) Viking and Magellan, (b) Apollo and Gemini, (c) Messenger and Mercuris, (d) Viking and Curiosity, (e) Magellan and Venera Olympus Mons is: (a) a large shield volcano on Mars, (b) a large shield volcano on Venus, (c) a large impact basin on Mars, (d) the name of an outflow channel on Mars, (e) a feature on Mars' moon phobos Which processes below are examples of weathering? (a) landslides, (b) frost wedging, (c) movement of dust during dust storms, (d) oxidation (rusting of rocks with iron-rich minerals), (e) b and d A huge and long canyon on Mars, containing grabens and multiple grabens is: (a) the Valles Marineris, Olympus Mons, (c) the Tharsis rise, (d) Alpha Regio, (e) Aphrodite TerraExplanation / Answer
4. e) All the above .
Mars spherules are also known as blueberries,this is due to their blue hue in false color images.These are the abundant spherical hematite inclusions discovered on the Mars.
Ripple marks are very commonly preserved in sedimentary rock here on Mars surface.
Valley networks are basically found only on the ancient cratered terrains on Mars surface.
5.a) pancake domes
Venus’ surface has circular features called volcanic domes. These are 65 kilometers in diameter. Sometimes these are referred to as "pancake" domes, they basically represent a unique category of volcanic extrusions on Venus surface formed from viscous (sticky) lava.
6) e) Folded mountains occur over some areas of Venus,these appear because of upwelling mantle plumes(hot spot) and mantle plumes(cold spot)
