Why do we need to use radar to image the surface topography of Venus?
It is covered by a thick layer of ice
It is too far away for VL to travel back to Earth
Its surface is so dark it absorbs almost all VL
It is covered by a dense atmosphere that doesn't transmit VL
5
Which of these statements about Mercury are true?
it is composed of the element, mercury
it is consistently hot because of its proximity to the Sun
