When the depth of trench is large or when the sub - soil is loose, the sides of the trench may cave in. The problem can be solved by adopting a suitable method of timbering.
coninental trenches are trenches that go across countries...i think
Trenches are caused by plate movement.
Reserve trenches
In the Trenches was created on 2007-01-30.
Reserve trenches were used as supplies for the trenches out the front. In world war one, they had come up with a technique of hiding in trenches before they fight. To do this properly, they had made them zig-zags. The trenches on the front line were where the soldiers would fight from. Reserve trenches were used in case these people had anything happen to them and they needed to use more trenches and more men. Throughout the war, the conditions of the front line trenches became worse as the communication and reserve trenches improved. I hope that helped :)

William H. Storms has written: 'Methods of mine-timbering' -- subject(s): Mine timbering
Timbering is necessary to provide wood for various construction and manufacturing purposes, such as building houses, making furniture, and producing paper products. It also helps manage forests sustainably by controlling tree populations, promoting forest health, and reducing the risk of wildfires. Additionally, timbering provides economic opportunities for communities dependent on forestry and contributes to the overall economy.
