Which features on mars point to the possibility of liquid water on the planet? impact craters with sharp rims volcanic cones with craters gullies and stream-like channels mountain ranges with faults

gullies and stream-likke channels

gullies and stream-like channels  

Explanation:

Water on Mars exists in the form of ice in polar ice caps and in the form of vapor in a very small quantity in its atmosphere. It is considered that billion of years ago, Mars must have denser atmosphere and its surface would have large amount of liquid water.

NASA mission-Curiosity rover on planet Mars sent back images of its surface providing direct evidence of liquid water on the planet in 2012. The images showed the gullies and stream-like channels where once the liquid water flowed vigorously.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

they should be similar or the same
