Question

activity a: mountain rivers get the gizmo ready: - check that mountain river and short - term erosion are selected. - if necessary, click outside the circle to close the zoomed - in view. introduction: erosion occurs when sediments and other materials are moved from one place to another. along with weathering, which is the breakdown of large rocks into smaller sediments, erosion can have a profound impact on the landscape. question: how does river erosion affect landscapes in the mountains? 1. label: first, get to know some of the different parts of a mountain river. turn on show labels. label the image to the right, then fill in the word that goes with each description. a small stream that flows into a larger river: ____ a place along a river where water drops straight down: __ a letter that describes the shape of a typical mountain valley: __ the side of a river: __ the bottom of a river: ____

Explanation:

1. A small stream that flows into a larger river is a "tributary" (by definition of river systems, tributaries feed into main rivers).
2. A place along a river where water drops straight down is a "waterfall" (matches the description of vertical water flow in a river).
3. A typical mountain valley has a "V - shape" (geographically, mountain valleys formed by erosion often have this shape, represented by the letter 'V').
4. The side of a river is the "bank" (standard term for the lateral edge of a river).
5. The bottom of a river is the "bed" (standard term for the river's lower surface).

Answer:

A small stream that flows into a larger river: tributary
A place along a river where water drops straight down: waterfall
A letter that describes the shape of a typical mountain valley: V
The side of a river: bank
The bottom of a river: bed
