The faults in which the hanging wall moves down relative to the footwall is called normal fault.
Explanation:
There are several types of faults based on their characteristics. One of them is the normal fault, or normal dip-slip fault. The main characteristic of this fault is that its hanging wall moves down relative to the footwall, while the footwall tends to move up relative to the hanging wall. The force that creates this type of faults is the vertical compression as the crust of Earth is lengthening.
- These faults can be found all over the world, and they are actually the most common type of faults.
- The normal dip-slip faults are bounding big portion of the mountains, as well as rift valleys.
- As these faults progress with their formation, with the footwall going up, and the hanging wall going down, the footwall becomes a hill or a mountain, while the hanging wall becomes a valley.
- The normal dip-slip faults can be found at all types of tectonic plate boundaries.

The Forestry Department is using a <u>chemical</u> control method. This involves using a <u>foliar spray </u>method, in which department personnel will spray pesticide directly on the trees’ leaves.
Explanation:
The chemical control method of pesticide control involves spraying chemical pesticides directly on leaves, shoots or roots of the plants. These chemicals are toxic to the pests only and the pests get retracted from the plants because of the pesticides applied.
A selective pesticide application is done to limit application to a target harmful pest which kills only that and does not harm the other useful or harmless species which thrives on the plants.
White pine blister causes rust of the branches and leaves of the pine trees. Hence, a foliar spray of the pesticide is done to control its spread.
