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 alters the slope (steepness) of the stream's path. Stream gradient refers to this slope. This change in gradient will indirectly affect velocity, but the direct characteristic modified by raising the left edge is the gradient itself; sediment and volume are not changed by this action.

Answer:

gradient of the stream
