Concepts of atmospheric pressure and wind formation — task. Chemistry CBSE Live product, Class 8 (2026-27).

Give the suitable answer:

1. A rubber sucker sticks tightly to a tiled wall when pressed because

higher atmospheric pressure outside presses the sucker against the wall
friction between rubber and wall is very high
glue inside the sucker holds it to the wall
the sucker produces a magnetic force

2. Winds are produced mainly because

clouds causes the wind by pushing the air
differences in air pressure cause it to move from high to low pressure regions
the moon's gravity pulls air
the earth's revolution pushes the air sideways
