what process breaks down rocks into smaller pieces without changing their chemical composition

Explanation:

• For the first question, cultural diffusion is the spread of cultural elements from one place to another. Sushi is a cultural - food element from Japan spreading to the US, which is an example of cultural diffusion. The other options are natural - geological or astronomical phenomena.
• For the second question, polar regions are characterized by cold temperatures with long winters and short summers due to their high latitudes and low solar radiation.
• For the third question, physical weathering breaks down rocks into smaller pieces without changing their chemical composition. Chemical weathering changes the chemical makeup, erosion is the movement of weathered material, and deposition is the laying down of eroded material.

Answer:

1. C. The spread of sushi from Japan to the United States
2. C. Cold with long winters and short summers
3. Physical weathering (not given as an option in the visible part of question 3, but the correct answer conceptually)
