69/5/52+ question 29 The main greenhouse gases in the atmosphere of the terrestrial planets are Aozone and carbon monoxide carbon dioxide and water vapor hydrogen and heliu oxygen and nitrogern methane and ammonia Question 30 The shape of Earth's magnetosphere is modified by AEarth's own gravity nasymmetries in the shape of Earth's core c the solar wind D Earth's elliptical orbit the Moon's tidal foece Question 31 Given the thickness and chemical composition of Venus's atmosphere, by how much would you expect its average surface temperature to change between day and night? The answer depends on where Venus is in its orbit around the Sun nBy tens of degrees K (like Earth) By hundreds of degrees K (like Mercury) D There should be almost no change in temperature Question 32 What is the habitable sone? A the zone around a star where liquid can exist the zone around a star where liquid water can exist the zone around a star where planets have oxygen in the atmosphere D the location on the sky where planets can be found Question 33 What is a secoedary atmosphere? the atmcsphere that escapes the gas closest to the planet surface the atmosphere that remains after the planet has formed the gas captured during the planet's formation the gas farthest from the surface Question 34 Albodo measures the amount of sunlight reflected by a planet False as According to the conservation of angular monsent um, if an ice-skater who is spinning with her arms out wid slowly palls them close to her body, this will cause her to..... A spin faster D fall dow maintain a constant rate of spitn D spin slower

Explanation / Answer

29)

B - Carbon dioxide and the water vapour = proportion of the water vapour in the green house gases is the 95 % and the proportion of the CO2 in the greenhouse gases is the 3.2% only and all other gases are below these concentrations.

30)

C = The solar wind. Planets having active magnetospheres, like the Earth, are capable of mitigating or blocking the effects of solar radiation or cosmic radiation. and these magnetospheres saves the many creatures or the humans in the earth and because these are solar radiations which generally overlapped the magnetospheres like the blanket causes to modify the shape of the magnetosphere

31)

D - There should be almost no change in the temperature= The venus surface temperature is conastant at about 460 degree C and it reamins constant for day and night and for equator or poles because it has very thick atmospheric cloud which has a large volume of greeanhouse gases which trapped the heat thats why it is hot

32)

B- the zone around the star where liquid water can exists = The habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.
