An object rests on an inclined surface. If the surface is made steeper, what does the normal force on the object do?
Increase
Decrease (i think this is right, but just checking)
Stay the same
Normal Force is zero (pretty sure its not this)
cannot be determined (pretty sure its not this)

You are correct, it would decrease. Just think of the extreme case, if you tilt the surface to a 90 degree angle, the object would fall off, so the normal force on it would be zero.

This will be according to the inclination angle , so for a steeper surface , the normal force will increase the object , as long as it is rested

As a free-body diagram would show, the normal force would decrease, and the force pulling the object down the plane would increase. (These two forces are two perpendicular components of gravitational attraction).
