Because of the amount of iron in the soil. When iron oxidizes, it becomes red, like rust on a bicycle left outside for too long. So since the iron in Mars' soil has oxidized, the soil is red.
No, it is a red-orange color due to the deposition of iron (or, due to the high iron content of the soil), hence the name "The Red Planet"
i think mars
The red colour is caused by iron compounds in the soil. Iron is bonded to oxygen, not mixed with it.
The reddish color is appropiate for some tree's and plants the soil is their main resource given by nature Australia has very little water and to much heat ANSWER The soil is red because it contains a high proportion of iron oxides.
Iron oxides account for the red tint to soil .
Iron oxide colors soil red.
Generally red soil is a sign that it contains iron oxides.

The red comes from high iron deposit in the soil.
Laterite soil is red in colour due to the presence of oxides of iron.
bcause the red soil has iron in it & the black soil is formed frm d rock basaltic which is black !
Iron bearing minerals which oxidise to red/brown Iron Oxides (rusts).
Laterite soil is red in colour due to the presence of oxides of iron.
The soil in the Australian outback is high in iron. When iron comes into contact with air it rusts causing the soil to turn red...
