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.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
