Please help ill mark brainlist (no bots or links ill report u) what happens when two continental plates of similar densities collide?

A ) They are both pushed back down into the mantle.
B ) They buckle upward and form mountains.
C ) They remain level since densities in both places are equal.
D ) One plate rides over the other and forms a trench.

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
