it was too close to the sun, this dried up all the water.
No. Venus is far too hot for water to exist on its surface.
yes meteors hit Venus surface the craters that were once on the surface disappear
Radar has been used to map the surface of Venus
It would need to be a lot cooler have a rocky surface with water and oxygen
Venus has the highest surface temperature of all the planets.
If the water table drops the water may no longer be able to surface as a spring so water will disappear from the surface of the desert and the oasis will disappear.
No. Venus is far too hot for water to exist on its surface.
the surface feature of Venus are craters, meteorites and mostly acid water
yes meteors hit Venus surface the craters that were once on the surface disappear
There is no known evidence of liquid water every having existed on Venus, but it is quite possible that surface conditions were once very different from what they are now. Note that the surface of Venus has not been studied as extensivley as the surface of Mars.
No, there is no rainfall on Venus, even if there was, the water would evaporate before it even touched the surface as it is about 400 °C.
Because on Mars it is too cold so any water on the surface is frozen, while on Venus its too hot.

The "topography" of Venus is the three dimensional shape of the surface of Venus.
The atmosphere on the surface of Venus is cloudy.
Mercury, Venus, Mars, Pluto have rock as surface Earth has water and rock as surface Uranus and Neptune have ice as surface(under the ice there's water) Jupiter and Saturn have no surface at all
