Whether Earth is an exception of any of the properties discussed in the table or not.
Answer to Problem 1CC
Solution:
Earth is not an exception of any of the properties discussed in the mentioned table.
Explanation of Solution
Introduction:
There are two classes of planets in our solar system namely terrestrial planets, which formed closer to Sun and Jovian planets, which formed away from the Sun.
Explanation:
The first and third properties discuss the size and composition of the terrestrial planets and their distance from the Sun compared to those of Jovian planets respectively. Earth is a terrestrial planet that formed close to the Sun. Thus, its core is made up of rocky materials, primarily of iron and nickel. Also, since at the distance of Earth’s orbit the hydrogen compounds couldn’t solidify, these compounds did not contribute in the formation of the core. Due to this reason, Earth has a comparatively smaller size than the other planets in the solar system and a rocky core.
The second property discusses the direction and orientation of the orbits of the planets. All the planets including Earth orbit the Sun in the same direction, and almost all the planets of our solar system lie in same plane. This is due to fact that they formed from the same protoplanaetary disk.
Conclusion:
Thus, Earth is not an exception of any of the properties discussed in the table.

- 4b) the average density of the earth is 5.5 g/cm^3. Which has the greater density 1g of uranium of planet earth 4c) which has the greater density -5kg of lead or 10kg of gold? 4d) which has the greater density-5kg of osmium of 10kg is steel? ANSWER ALL PLZ!!arrow_forwardLook at Figure 21-11. Which molecule(s) can escape from Earths gravity? From Mars? From Venus? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies. The lines represent the typical highest velocities of molecules of various masses. The Jovian planets have high escape velocities and can hold onto even the lowest-mass molecules. Mars can hold only the more massive molecules, and the Moon has such a low escape velocity that even massive molecules can escape.arrow_forwardExamine Table 18-2.

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_forward
- We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals. a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ? b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Eartharrow_forwardIf the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars?
