Answer:
a) process
- saltation,
- rolling and traction
- suspension.
b) High flow velocities
Explanation:
The process by which sediments are moved by streams are
- saltation,
- rolling and traction
- suspension.
The flow velocities that can erode sediments from the bed and keep them suspended in water have to be extremely high to be able to carry the sediments after agitating them from the River Bed. and this is dependent on the volume and capacity of the water body

Meandering caused the two oxbow lakes to be formed.
Explanation:
There are multiple different types of lakes, and the type of a lake is determined by the manner in which it has been formed. One of the lake types is the oxbow lake. This type of lake form from the preexisting meanders of the rivers, and they are located right next to a river, usually being separated by the river by only few meters.
When a river is meandering, which happens in flat terrain where the river is slow, it gradually takes up a snaky shape. This type of shape of the river can only go a certain point, till about 90 degrees angle of curvature. Once this angle is reached, the water starts to erode the sediment as it finds it hard to curl. Over time, the sediment is totally eroded, and the river continues in a straight line, cutting off the water to meandering parts, and separating itself from them. This results in the formation of oxbow lake, which is a bow-like, shallow lake.
Other types of lakes are:
- tectonic
- volcanic
- organic
- glacial

Answer:
Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. ... They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.
