# Arranging One Mesh Over Plane Mesh

I created a plane mesh (ground) and then another mesh (tree).

On right view, it seems like this:

However on top view, the tree doesn't seem there. I also tried boosting the z-value but it doesn't come on top of ground any how. (But for right view, it goes high if I change the z).

Also when I start tilting a little in the right view, It becomes like these:

And in render, it creates an unexpected shade on the tree which I believe the above problem is causing.
