Respuesta :

1. There is a greater chance of chemical weathering occurring in urban areas. The reason behind this phenomenon is that a humid and hot climate is the best suitable condition for chemical weathering to occur. This type of climate is found in urban cities and pollution can be considered a major contributor to this.

2. Four ways in which construction activities by humans contribute towards weathering are

Rocks and dirt are often dumped into rivers, altering the ecosystem of rivers and leading to weathering.

It leads to an increase in the temperature nearby, providing suitable conditions for chemical weathering to take place.

It pollutes the air, causing acid rain, which further contributes to weathering.

Changing the rock structure for usage in construction may lead to weathering.

3. The term used to describe the starting point of a river is headwater. The headwater may originate from mountain snowmelt or rainfall, it can also come from the earth's groundwater or form a lake or large pond's edge.
