SMBC Physics - Why are Stones Round feat. Zach Weiner

The video explores the formation of spherical and flat stones, highlighting how spherical stones lack a preferred orientation due to constant movement, while flat stones develop a preferred orientation due to gravity. The analogy of dumplings and biscuits illustrates this concept. The video also covers sedimentary rock formation and how gravity influences the structure of buildings, contrasting it with a hypothetical scenario in outer space.

Why do spherical stones appear the same from all sides?

• They are painted uniformly.

• They have no preferred orientation.

• They are formed in a mold.

• They are polished by humans.

What causes flat stones to have a preferred orientation?

• The type of minerals they contain.

• The direction of gravity.

• The way they are cut.

• Their color pattern.

How does gravity affect the shape of a biscuit compared to a dumpling?

• It has no effect on either.

• It makes the biscuit rounder.

• It flattens the biscuit.

• It makes the dumpling flat.

What happens to stones that are too heavy to roll in a river?

• They dissolve in water.

• They become spherical.

• They are worn down to be flat.

• They are carried away by the current.

Why do buildings have a layered structure with a basement, floors, and a roof?

• To follow traditional architectural styles.

• To make them look aesthetically pleasing.

• To save on construction materials.

• To align with the gravitational pull.
