Based on the analysis of the diagram and the provided table, here is the solution to matching the parts of the river with their correct labels.
The diagram illustrates a river from its source in the mountains to its mouth at the ocean, divided into three main sections: Upper Course, Middle Course, and Lower Course. Each section has distinct geographical features.
Here is the completed matching:
1. Upper Course (Leftmost Section):
This section is characterized by steep gradients and mountainous terrain.
- The red line pointing to the origin of the river corresponds to the
River source.
- The red line pointing to the steep drop in the riverbed corresponds to the
Waterfall.
2. Middle Course (Middle Section):
This section shows a river with a gentler slope, forming curves and bends.
- The red line pointing to the winding path of the river corresponds to the
Meander.
- The red line pointing to the smaller stream joining the main river corresponds to the
Tributary.
- The red line pointing to the flat land adjacent to the river corresponds to the
Flood Plain.
3. Lower Course (Rightmost Section):
This section depicts the river as it nears the sea, becoming wider and slower.
- The red line pointing to the curved lake that was once part of the river channel corresponds to the
Oxbow lake.
- The red line pointing to the wide, brackish area where the river meets the sea corresponds to the
Estuary.
- The red line pointing to the fan-shaped deposit of sediment at the river's end corresponds to the
Delta.
- The red line pointing to the large body of saltwater corresponds to the
Ocean.
Therefore, the correct matches for the worksheet are:
-
Upper Course: River source, Waterfall
-
Middle Course: Meander, Tributary, Flood Plain
-
Lower Course: Oxbow lake, Estuary, Delta, Ocean
The terms "River mouth" and "UPPER COURSE" (as a heading) are also present in the table but are not explicitly pointed to by a red line in the diagram for matching. The "River mouth" is the general area where the river enters the ocean, which is encompassed by the "Estuary" and "Delta" features. The term "UPPER COURSE" is a category label, similar to "MIDDLE COURSE" and "LOWER COURSE," rather than a specific feature to be matched to a single red line.
Parent Tip: Review the logic above to help your child master the concept of parts of a river worksheet.
