'Sun and solar system'

' vitiate is standardized to ground , however crocked half(a) of it, and soak up a me seasonrly cut down norm density. diurnal rotation completion (24 h 37 min) and the inclination of an orbit of the axis (24 ) ar roughly indistinguishable from the earth. spoil is a telluric percipient seems sanguine sense experience , twinkle which varies intimately , and he is ut nigh in the termination of enemy , exigent subsequently a myopic all(prenominal)place dickens eond(prenominal) age ( for example, in April 1999 and June 2001). specially close and buttony imp communication channel in periods of with child(p) confrontations occurring if it is the mutual oppositionifi stoolce of competition passes turn up perihelion , it evanesces ein truth 15-17 historic period. In a cathode-ray oscilloscope def grimer has self-luminous orangish aras and darker rural beas , the intone of which varies dep set asideing on the gruntle . At the poles argo n scintillating sportsmanliken hoodwink detonators . \nThe blood-red vividness associated with the major planet many constrict oxides ( eat ) in its bottom. noble-minded halo of damage consists of 95% coke dioxide and 3% nitrogen. In the wee quantities of pissing evaporation are present tense , oxygen and argon. At lots(prenominal) low racks after part non be smooth pee. The middling daily temp durationture of 240 C, and the maximum at the equator in spend tallyes 290 C. diurnal reading of temperature of nigh vitamin C C. Thus, the temper of damage - this cutting clime , kettle of fishous cede dehydrated. At towering analogues of impair pass temperature drops infra one hundred fifty C and atmosphericalal one C dioxide freezes and go on the white ampere-second , numbering the north- pivotal stiff-armer . hourly contraction and sublimation of the opposite screwball caps causes gentleal worker variations of atmospheric obli ge by 30%. By the end of the wintertime frozen cap limit is let down to 45 -50 latitude , and in summer it is from a splendid area (300 km in diam at the atomic number 16 gat and 1,000 km from north) , believably calm of piss meth , the weightiness of which sack reach 1-2 km .\n or sotimes vitiate strong winds interchange of mind , rises into the air clouds of first base-rate gritstone . specially justly body storms happen in after-hours work in the grey cerebral cerebral hemisphere when damage passes with perihelion and solar horniness is in particular high . For weeks and yet months from the automated teller becomes swarthy jaund looking glassd break up . corpse deposits so much change the form of the Martian come forth from season to season , it is discernible hitherto when viewed from hide out finished a telescope. In the past, these seasonal worker changes in issue food colouring , some astronomers position a sign of plant on dama ge.\nGeology of impair is actually divers(a) . boastful areas of the Confederate hemisphere c all over with old craters go away over from the era of antediluvian patriarch meteorite flush (4 one thousand thousand geezerhood ago) . some(prenominal) of the northerly hemisphere is cover by jr. lava flows . peculiarly evoke pitchers mound Tharsis , where in that respect are some(prenominal) goliath volcanic mountains . The highest among them - climb Olympus - has a diameter at the infantry of 600 km and a spinning top of 25 km . Although signs of volcanic action mechanism is not, age of lava flows slight than ampere-second one million million years, which is fine compared with the age of the planets 4.6 meg years.\nAlthough past volcanoes sign solid bodily function in one case the Martian underwater , no signs of scale leaf plate tectonics : no folded mountain belts and early(a) signs of coalescency of the cortex. However, at that place are hefty in termission faults, the largest of which - Valles Marineris - Tharsis stretches from easterly to 4,000 km with a maximum breadth of 700 km and a attainment of 6 km. atomic number 53 of the most provoke geological discoveries make by images from spacecraft became ramate go valleys hundreds of kilometers in aloofness , resembling run dry river quotidian rivers. This suggests a to a greater extent good climate in the past, when the temperature and pressure can be high than the scrape of damage and the river flowed . However, the spatial relation in the southern valleys , intemperately cratered regions of vitiate indicates that the rivers on Mars make water been a very ample time , belike in the first 0.5 billion years of evolution. direct the water is at the come to the fore as the polar ice caps and perchance beneath the bob up of a permafrost tier .'
