learn and observe air resistance by throwing objects from considerable height a; tissue paper b: plastic spoon c: stainless steel spoon take a record of your findings and observations and jot them down.

Speed: Tissue fell slowest(lowest mass and large surface area acts as parachute)

Plastic spoon fell pretty quick

And the stainless steel spoon fell the fastest because of the weight and small mass

The tissue is the only item out of the 3 that makes 0 noise when it hits a surface.

a physical change is being made.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
