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

When a maritime tropical air mass is cooled by a colder ground surface the weather is often A: stays nearly the same but the sur
Kitty [74]

B: becomes foggy or rainy because cool air holds less water vapor.

Explanation:

The maritime tropical air masses are warm and humid, while the air masses forming over the land tend to be dry, in some parts are cold and in some parts hot. When these two collide, the weather rapidly changes. If the maritime tropical air masses moves toward the colder ground surface, then the weather will become foggy or rainy.

The reason for this is that the water vapor in the maritime tropical air mass will start to condensate because of the lower temperatures, so precipitation will form. The precipitation is usually manifested through rainfall, while in the mornings it tends to be foggy.
