Explanation:

Question 4

An electrical current in a classroom is typically carried by wires (conductors) connected to electrical outlets, which are part of the building's electrical system, allowing devices like lights, computers, etc., to receive electricity.

Sandstone arches in the Colorado desert are formed by the process of erosion, specifically wind erosion (and sometimes water erosion) that wears away the sandstone, leaving behind arch - like structures as softer rock is eroded more quickly than harder layers.

Water is a force that is both constructive and destructive to Earth’s surface features. Constructively, it deposits sediments (e.g., forming deltas), and destructively, it erodes land (e.g., forming canyons). Wind is also a valid answer (constructive: deposits sand dunes; destructive: erodes rock). Ice can also be considered (constructive: deposits glacial till; destructive: erodes via glaciation).

Answer:

Through electrical wires (connected to power sources like outlets, carrying current to devices like lights, computers in the classroom).
