Question

a stream table is a tool used to show how water causes erosion. water from the left side of the table is added to model a stream. suppose a block of wood is placed under the left edge of the table. which characteristic of the stream is changed? gradient of the stream sediment in the stream velocity of the stream volume of the stream

Explanation:

Placing a block under the left edge of the stream table changes the slope of the table. The gradient of a stream is related to the slope of its channel (or in this case, the stream table). Sediment, velocity, and volume aren't directly changed by altering the table's slope at the left edge; the slope change affects the gradient.

Answer:

A. gradient of the stream
