Why is Venus so Hot?
The planet Venus is named after the Roman
goddess of beauty and love. It is the brightest planet in the Solar System. It
is
visible
as a star. Venus is much hotter, because it is much closer to the Sun. The atmosphere there is 90
times
thicker than that of the Earth and the surface is
hidden in a white cloudy cloak.
This thick atmosphere acts like a blanket
which holds
back the heat of the Sun and turns the midday temperature to 4800C.
The atmosphere on Venus consists mainly of
the carbon
dioxide gas which acts as a greenhouse roof,
trapping the Sun's heat. The rocks on Venus are hotter than boiling water. Above the
rocks, winds blow at a speed of 320 km/hour.
