These are all T/F Questions
Stochastic resonance is an explanation for rapid climate change, which states that a stable long term climate mode can be rapidly forced into a short term mode of instability by a random variation(s) in Earth systems.
On Venus, global atmospheric circulation travels at a speed estimated to be 60 times the rotation speed of the planet. Planetary scientists refer to this atmospheric condition as "super rotation."
One reason scientists think that a meteorite or large body of rock hit the Yucatan peninsula area 65 million years ago is the presence of shocked quartz.
Phoenix detected the highest concentrations of water in soil (dielectric) on Mars during the day (local solar time).
Phoenix detected and imaged falling snow on Mars.
The Mars rovers confirmed ripple marks, sedimentary structures, salt compounds , and dust devils on Mars.
Weathering of silicate rocks takes CO2 out of the atmosphere and Volcanoes inject CO2 back in atmosphere.
When a Russian ice shelf region was above sea level, tundra vegetation pulled carbon dioxide from the air as plants grew. That organic material, much of which didnt decompose in the frigid Arctic, accumulated in the soil and is the source of modern methane.
El Capitan, in Yosemite National Park, was formed primarily by the flow of water over tens of thousands of years.
Jupiter's moon, Europa, is a potential model for investigating the Snowball Earth hypothesis.
A professor at CU successfully demonstrated that water beneath Greenland's ice sheet was the cause of the ice sheet's increased movement. (from class video)
About 15,000 years ago, an ice dam holding back Glacial Lake Missoula broke and caused massive flooding. This flooding caused the formation of the Great Lakes in over a period of just several months.
The decay of radioactive material in the Earths crust and mantel does not account for the lack of solar flux from the relatively "faint sun" in past climates.
In a volcanic eruption cloud, there are small particles of volcanic material colliding with one another at high speeds, and these collisions can result in separation of charges in the volcanic cloud that result in lightning.
Explanation / Answer
True: Stochastic resonance is a phenomenon when there is increase in quality of signal rather than decrease when there is increase in the level of random noise. This is used by physcists, biologists, geologist etc. So the stochastic resonance is an explanation for rapid climate change which states that a stable long term climate change can be rapidly forced into a short term mode of instability by a random variations in the earth systems
True: Venus rotates rotates in 243 earth days to complete its one rotation but its atmosphere is rotating at speed of 200 meters per second or takes about 4 earth days to travel the same distance and hence the wind in the Venus moves faster at a rate of about 400 km/hr. This phenomenon in which the global atmospheric circulation is 60 times faster than the planet itself known as super rotation
True: beneath the Yucantan Peninsula,Chicxulab crater was found in Mexico. This crater coincides with the K-T boundary. The evidence of impact crater was the discovery of shocked quartz, tektites and a gravity anomaly in that area.
True
True
true: Now there is confimed that aeolian landforms like ripple marks, sedimentary structures, salt compounds and dustdevils occur in Mars
True: weathering of silicate rocks consume CO2 as used primarily in chemical weathering whereas the volcanoes eject CO2 back into the atmopshere.
True
False: El Capitan, Yosemite National Park is made of granitic rock which is formed at considerable depth within the earth by solidification of the molten rock and their subsequent erosion of the overlying rock
True: Europa one of the moon of Jupiter has a frozen icy surface and beneath its surface there is possiblity of existence of an ocean and this can led to understand the other planets in the solar system . The Europa model can be used for investigating the snowball earth hypothesis.
True: Water beneath Greenland ice sheet cause of increase ice movement because water acts a lubricant and reduces the friction and hence accelerate the speed of ice movement
False: The Great lakes were formed in an average period of about 55 years and the floods occured many times between 15,000-13,000 years ago.
True : The decay of radioactive material and mantle is not associated with the solar flux
True: the volcanic lightning is due to collision of charged particles from either the material that is ejected from the volcanic cloud or the formation of charged particle within the ash clouds which move through the atmosphere
