gravity can change the motion of an object because of magic
Yes. As acceleration due to gravity increases so does the object's weight. The reverse is true when gravity decreases. Mass, however, does NOT change with gravity.
Air has no effect on gravity. But the presence of air can change the response of an object to the force of gravity alone.
Yes. What you weigh depends on the gravity of the planet you are on.
Einstein said gravity acted by curving space in response to matter.
You can not change a paper size to landscape, landscape is an orientation, not a size.
Landscape
It changes the landscape by blowing over or on the landscape
No
because you are an idiot
Humans have changed the Australian landscape by introducing non-native species, clearing land for agriculture and urban development, constructing dams for water management, and altering fire regimes. These changes have led to habitat loss, fragmentation, and degradation, impacting native flora and fauna. Efforts are being made to restore and conserve the natural environment in Australia.

Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
