Chapter 19, Problem 4LTL
Look at Figure 19-9. Rising from Earth’s surface to the cloud layer shown, does the temperature increase, decrease, or stay the same? How about from the clouds to the ozone layer? At about what altitude does the temperature change most abruptly, almost 400°F in 30 km?

- Astronomers believe that the deposit of lava in the giant mare basins did not happen in one flow but in many different eruptions spanning some time. Indeed, in any one mare, we find a variety of rock ages, typically spanning about 100 million years. The individual lava flows as seen in Hadley Rille by the Apollo 15 astronauts were about 4mthick. Estimate the average time interval between the beginnings of successive lava flows if the total depth of the lava in the mare is 2 km.arrow_forwardAn image of the disk of the Sun shows a higher brightness at the centre compared to the edges. Explain with the aid of a sketch the reasons for this darkening at the limb of the solar disk. In images of the solar photosphere there are small regions of the solar disk, about 500 km across, which are about 2.5 times brighter that the surrounding photosphere. Assuming a temperature of 5800 K for the background photosphere, calculate the temperature of these photospheric bright points. One explanation for these bright points is that the density is lower in these regions. Explain briefly how that could produce the observed brightening.arrow_forwardDescribe how a convection current works. In a simple way.arrow_forward
- equattion : S/4 (1- a) = f*sigma*TS4 Solar Constant (W/m2) S = 1361 How sensitive is the temperature of the earth to changes in the atmospheric transmissivity (f)? The atmosphere is more transmissive (lets more radiation through) when CO2 and other greenhouse gases are lower. During the pre-industrial period, transmissivity (f) was probably around 62% (f = 0.62) and has been decreasing. Calculate how much the Earth's surface temperature would change if the transmissivity changes by ±0.01 (to 0.60 or to 0.62). ___ °C per 1% transmissivity change.arrow_forwardKnowing Earth’s rotational frequency W = 7.3 x 10-5 s-1 and the characteristic frequency 1/T=U/L of a particular oceanic motion based on its velocity (U), temporal (T) and spatial (L) scales, a) What is the non-dimensional Rossby Number and What does it mean if this parameter value is lower than one?arrow_forwardThe number density of air in a child's balloon is roughly the same as sea level air, 1019 particles/cm3. If the balloon is now 16 cm in diameter, to what diameter (in km) would it need to expand to make the gas inside have the same number density as the ISM, about 1 particle/cm3?arrow_forward
- In the graph from the class handout the inflow of energy from the sun is given as a constant 236 watts per meter squared. To get this figure we used L(1 – a) × 236 W/m², where L = 1350 W/m²is the solar constant, and a = 0.3 is the Earth's albedo (meaning that 30% of the Sun's energy is reflected back into space). The 1/4 comes from averaging the arriving solar energy over the whole Earth (the surface area of the Earth is 4 times the area of the "disk of energy" hitting the Earth.) Using these ideas estimate the inflow of energy to a planet if the solar constant is 647 watts per meter squared and the planet's albedo is 0.5. Round your answer to the near 10 watts per square meter.arrow_forwardUnder what conditions can the outer surface of a vertical cylinder be treated as a vertical plate in natural convection calculations?arrow_forwardHow does the Earth's magnetic field work, and what is its role in protecting us from the solar wind?arrow_forward
- In general what would be the most effective means for making the atmosphere more unstable? Warming the mid-levels (e.g., 500mb level) and cooling the surface. Cooling the mid-levels (e.g., 500mb level) and warming the surface. Warming both the mid-levels (e.g., 500mb level) and the surface. Cooling both the mid-levels (e.g., 500mb level) and the surface.arrow_forwardCO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.arrow_forwardWhy do small planets cool faster than large planets? Choose any two of the five Terrestrial worlds and calculate for each one the ratio of its surface area to its volume. Why is this ratio important? (Hint: Does this ratio have anything to do with the ability of a planet to lose internal heat?) (Note: The surface area of a sphere is 4r2, and the volume of a sphere is 43r3.)arrow_forward
